What weight of ice is melted at 0°C by the heat liberated by condensing 180 g of super heated steam at 150°C (b.p of water=100°C, heat of vaporization =540 cal g¹, heat of fusion of ice =80 cal g¹, specific heat od steam=1.6 cal g¹ degree ¹.
Answer: 1395 grams of ice can be melted
Explanation:
To find the weight of ice that is melted by the heat liberated by condensing 180 g of superheated steam at 150°C, we need to use the following information:
The boiling point of water is 100°C
The heat of vaporization of water is 540 cal/g
The heat of fusion of ice is 80 cal/g
The specific heat of steam is 1.6 cal/g°C
First, we need to calculate the total heat energy released by the condensation of the steam. This can be found by using the heat of vaporization and the amount of steam being condensed:
180 g x 540 cal/g = 97200 cal
Next, we need to calculate the heat energy absorbed by the steam as it cools down from 150°C to 100°C. This can be found using the specific heat of steam and the change in temperature:
180 g x 1.6 cal/g°C x (100 - 150) = -14400 cal
Now, we can subtract the heat absorbed by the steam from the total heat released by the condensation to find the heat energy available to melt the ice:
97200 cal - (-14400 cal) = 111600 cal
Finally, we can divide this heat energy by the heat of fusion of ice to find the weight of ice that can be melted:
111600 cal / 80 cal/g = 1395 g
Therefore, 1395 grams of ice can be melted
Why do you think acetic acid and isopropyl alcohol have different properties?
Acetic acid and isopropyl alcohol have different properties because they have different chemical structures.
Acetic acid, also known as ethanoic acid, is a carboxylic acid with the chemical formula CH3COOH. It contains a carboxyl group (-COOH) which gives it acidic properties, and it also has a methyl group (-CH3) attached to the carbon atom next to the carboxyl group.
Isopropyl alcohol, also known as isopropanol, has the chemical formula C3H8O. It is a simple alcohol, which means that it contains a hydroxyl group (-OH) attached to a carbon atom. This hydroxyl group gives it some of the characteristics of a polar solvent, but it does not have any acidic properties.
Due to these different structures, acetic acid is a stronger acid than isopropyl alcohol, and isopropyl alcohol is a better solvent for non-polar compounds. Additionally, Acetic acid is more viscous and has a higher boiling point than Isopropyl alcohol.

b) The limiting reactant is Al
c) The percent yeild is 95%
What is the reaction?We can say that a reaction has taken place when there is the combination of two or substances in such a way that what we get is a new product. In the case of this reaction the combination is between aluminum and hydrochloric acid.
Number of moles of Al = 700g/27 g/mol

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of 3.04 cm contains 35.3 g of heptane and 38.1 g of water. What is the combined height of the two liquid layers in the cylinder? The volume of a cylinder is π r2h, where r is the radius and h is the height.
Combined height of the two liquid layers in a cylinder is 11.65 cm.
What are the volumes and heights of liquids?In order to find the combined height of the two liquid layers in the cylinder, we need to find the individual heights of the heptane and water layers by using the density and mass of each liquid to find the volume, and then use the volume and radius of the cylinder to find the height.
To find the volume of the heptane layer:
mass of heptane / density of heptane = 35.3 g / 0.684 g/mL = 51.7 mL
To find the volume of the water layer:
mass of water / density of water = 38.1 g / 1.00 g/mL = 38.1 mL
The radius of the cylinder:
diameter of cylinder / 2 = 3.04 cm / 2 = 1.52 cm
Height of the heptane layer:
volume of heptane / πr^2 = 51.7 mL / (3.14 x (1.52 cm)^2) = 6.66 cm
Height of water layer:
volume of water / πr^2 = 38.1 mL / (3.14 x (1.52 cm)^2) = 4.99 cm
Combined height of the two liquid layers:
height of heptane layer + height of water layer = 6.66 cm + 4.99 cm = 11.65 cm

how do we know that we need osmosis  to make water splitting work efficiently?
Answer: hey sorry im late but i think this will help with ur answer
Osmosis is the diffusion of water molecules through a selectively permeable membrane, from an area of higher concentration to an area of lower concentration. In the context of water splitting, osmosis is needed to make the process more efficient because it helps to separate the hydrogen and oxygen ions that are produced during the process.
When the water is split into hydrogen and oxygen, the hydrogen ions and oxygen ions will tend to want to recombine because they have an electrostatic attraction towards each other. If they recombine, it would be difficult to separate them again. But by using osmosis, we can separate the hydrogen ions and oxygen ions by creating a selectively permeable membrane which only allows water molecules to pass through but not the hydrogen and oxygen ions. This way, we can keep the hydrogen and oxygen ions separate, and prevent them from recombining.
Additionally, water splitting process requires a high energy input to separate hydrogen and oxygen from water. Osmosis can be used to decrease the energy input required for water splitting by creating a concentration gradient. This is because the concentration gradient can be used to drive the water splitting reaction, allowing it to occur at lower energy inputs, making the process more efficient.
In summary, osmosis plays a crucial role in making water splitting work efficiently by providing a way to separate the hydrogen and oxygen ions produced during the process and by decreasing the energy input required for water splitting by creating a concentration gradient.

Because we obtain a significantly lower faradaic efficiency with saltwater, we are aware that it cannot be converted into hydrogen gas as effectively as pure water. Without osmosis, the Cl- in the saltwater produces side reactions that reduce the efficiency of water splitting.
What is Osmosis?
Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of higher concentration to one of lower concentration.
Any solvent, including gases and supercritical liquids, can go through the osmosis process.
Let's take a closer look at the various forms and consequences of osmosis.
Osmosis is the process by which solvents migrate from an area of lower solute concentration to one of higher solute concentration through a semi-permeable membrane. Instead, in diffusion, molecules migrate from an area of higher concentration to one of lower concentration without the need for a semi-permeable membrane.

What is impossible for a machine to do?
do a greater amount of work than the amount of work done on the machine
apply a force in a direction that is different than the direction of the force applied to the machine
move an object a greater distance than the distance that part of the machine was moved
apply a force that is less than the force that is applied to the machine
Doing a greater amount of work than the of work done on the machine is impossible for a machine to do. The energy given the system might loss some fraction and cannot be converted completely to output work.
What is work done ?Work done is a physical quantity that describes the result of a force or how effectively the force made a displacement. The force applied on a body if results in a displacement of the body, the force is said to be done work on the body.
Work done is a vector quantity, having both magnitude and direction. According to thermodynamic concept, then it is impossible to convert all the input energy into work done.
It is impossible to achieve a 100% of efficiency or more by a machine. Hence, doing greater amount of work than the input is impossible for a machine.

Please help with the following problem!
Both Kelvin and Fahrenheit are temperature scales.F = 1.8*(K-273) + 32 is the simplest formula for converting between Kelvin and Fahrenheit.
What is Temperature in Kelvin?In keeping with past centigrade scales, Kelvin prudently suggested that the temperature range between the ice point and the steam point initially be specified as 100 degrees. A temperature scale, which we use to determine temperature, is present on every thermometer
The Standard International (SI) unit of thermodynamic temperature is the kelvin (abbreviation K), often known less frequently as the degree Kelvin (symbol, o K). The formal definition of one kelvin is 1/273.16 (3.6609 x 10 -3) of the thermodynamic temperature of pure water's triple point (H 2 O).
Formula
This simple formula states that to find Kelvin temperature (K).
K = °C + 273The temperature is increased numerically by 273 to translate from the Celsius scale to the Kelvin scale. As a result, the kelvin scale and the Celsius scale have the following relationships.
T(K) = T(oC) + 273What is Temperature in Degrees Fahrenheit?The temperature scale known as the Fahrenheit scale was first proposed by physicist Daniel Gabriel Fahrenheit in 1724. (1686–1736). The unit is the degree Fahrenheit, represented by the symbol °F. There are a number of tales of how he initially created his scale, but the original publication states that the lower defining point, 0 °F, was set as the freezing temperature of a brine solution made from a combination of water, ice, and ammonium chloride (a salt). His best estimate of the average human body temperature, originally set at 90 °F and then 96 °F (about 2.6 °F less than the current figure due to a later revision of the scale), was the other limit established.
Fahrenheit to Celsius conversion
0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:
0 °F = -17.77778 °C
The temperature T in degrees Celsius (°C) is equal to the temperature T in degrees Fahrenheit (°F) minus 32, times 5/9:
T(°C) = (T(°F) - 32) × 5/9
Fahrenheit to Kelvin conversion
The temperature T in Kelvin (K) is equal to the temperature T in degrees Fahrenheit (°F) plus 459.67, times 5/9:
T(K) = (T(°F) + 459.67)× 5/9

how to calculate theoretical yield
Answer:
I'm not really sure how but here's the formula?
To calculate theoretical yield first check chemical equations are balanced. Calculate the mole ratios of the reactants and products, Find the theoretical yield of the reaction.
Percent Yield = Mass of Actual Yield / Mass of Theoretical Yield x 100 percent.
What is theoretical yield ?The theoretical yield is the quantity of product that stoichiometry predicts will be produced, whereas the actual yield is the amount that is actually produced.
The yield of a reaction is used to represent how much of a product is produced from that reaction.
Thus, Divide the ratio by the limiting reactant's molecular weight. The answer is the theoretical yield of the desired product in moles.

Explain the importance of two organelles present in plants cell
Answer:
Plant cells contain two organelles that are essential for their functioning. These are the chloroplasts and the vacuoles. The chloroplasts are the organelles responsible for photosynthesis, which involves converting light energy from the sun into chemical energy in the form of glucose. Without chloroplasts, plants would not be able to produce their own food. The vacuoles are large organelles filled with fluid that serve to store nutrients and other materials. Vacuoles also help to maintain the turgor pressure of the cell, which is the pressure that helps to keep the cell rigid and prevents it from collapsing. Without vacuoles, plant cells would not be able to remain rigid and would collapse, leading to the death of the plant.
