What are the non-renewable energy sources of energy Mcq?

Answers

Answer 1

One category of non-renewable energy sources is natural gas.

The fact that we currently rely on these resources to meet the majority of our energy needs makes the fact that they cannot be replaced once they are depleted a serious issue for humanity. There are no renewable energy sources like natural gas. It takes millions of years for a fossil fuel to form. We can only produce more until a finite amount of it remains in the earth. Because it comes from sources that were created over millions of years by the action of heat and pressure on organic materials, the vast majority of natural gas in the United States is classified as a fossil fuel.

In aqueous solutions, which type of bond or force has similar bond strength as ionic bond interactions?

Answers

The strength of hydrogen forces or bonds in aqueous solutions is comparable to that of ionic bond interactions. More powerful than the covalent connections between atoms.

Attraction between molecules and compounds. There aren't many powerful intermolecular forces. Covalently bonded molecules are capable of dissociating from one another when less energy is applied. This makes these chemicals very volatile. These bonding pairs of electrons result in the formation of ionic bond, which are the smallest part of a compound that preserves its chemical identity. This kind of link is created when two atoms from the same or nearly related elements in the periodic table come together.

Answers

Answer:

To calculate the concentration of A in mol/dm3, we need to know the molar mass of hydrochloric acid. Since the molar mass of hydrochloric acid is 36.46 g/mol, we can calculate the concentration of A by dividing the mass of hydrochloric acid, 7.30g/dm3, by its molar mass, 36.46 g/mol. This gives us a concentration of 0.2 mol/dm3 for A.

To calculate the concentration of B in mol/dm3, we need to know the molar masses of the elements in X2CO3. Since the molar masses of hydrogen, chlorine, oxygen, and carbon are 1.00 g/mol, 35.5 g/mol, 16.00 g/mol, and 12.0 g/mol, respectively, we can calculate the molar mass of X2CO3 as (21.00) + (135.5) + (316.00) + (112.0) = 90.90 g/mol.

Answers

The maximum mass of titanium that can be obtained from 500 tonnes of titanium(IV) chloride in this reaction is 24,000 tonnes.

The maximum mass of titanium500 tonnes x (1000 kg/tonne) x (190 g/mole TiCl4) = 95 x 10^6 g TiCl495 x 10^6 g TiCl4 x (48 g Ti/190 g TiCl4) = 24.7 x 10^6 g Ti.Therefore, the maximum mass of titanium that can be obtained from 500 tonnes of titanium(IV) chloride is 24.7 x 10^6 g.This can be calculated using the stoichiometry of the equation. First, calculate the number of moles of titanium(IV) chloride present in 500 tonnes.This is done by dividing the mass by the relative formula mass of the compound, giving 26,316 moles of TiCl4. The equation of the reaction shows that for every 1 mole of titanium chloride, 4 moles of sodium are required to produce 1 mole of titanium.Therefore, there are 104,264 moles of sodium required for the reaction. Since the mass of sodium is the same as its molar quantity, the mass of sodium required is 104,264 tonnes. Since the ratio of titanium produced to titanium chloride used is 1:1, the mass of titanium produced is 26,316 tonnes.This is equal to 24,000 tonnes when converted to kilograms.

Ethanol has a density that is about 0. 8 g/mL. This means that a certain volume of ethanol will ________

Answers

Ethanol has a density of approximately 0.8 g/mL, which means that for a given volume of ethanol, the mass of the ethanol will be 0.8 times the volume.

For example, if you have 100 mL of ethanol, then the mass of the ethanol would be 80 g. This density is slightly lower than the density of water, which is 1 g/mL, so a volume of ethanol will be slightly lighter than an equal volume of water.

Ethanol is a relatively volatile substance, meaning that it evaporates easily. At normal temperatures and pressures, it will evaporate at a faster rate than water. This means that if you have a certain volume of ethanol, some of it will evaporate over time, reducing the total mass of ethanol. In addition, ethanol has a lower boiling point than water, so it will evaporate more quickly at higher temperatures.

Ethanol has many uses, such as in fuel, as a solvent, and as an ingredient in alcoholic beverages. It is important to be aware of its density when measuring and using ethanol so that you can accurately measure and use the correct amount of ethanol for the desired purpose.

Answers

To determine the molarity of the acetic acid in the vinegar, we can use the information provided about the volume and concentration of the NaOH solution used to titrate it.

First, we need to calculate the number of moles of NaOH used in the titration:

moles of NaOH = concentration x volume

moles of NaOH = 0.48 M x 0.0186 L = 0.00884 moles

Since acetic acid (CH3COOH) and sodium hydroxide (NaOH) react in a 1:1 ratio, the number of moles of acetic acid in the vinegar is also 0.00884 moles.

To calculate the molarity of the acetic acid, we need to divide the number of moles by the volume of the vinegar solution:

Molarity = moles/volume

Molarity = 0.00884 moles / (unknown volume)

Answers

The molar solubility in water of Ag₂CrO₄ is ∛ 2x 10⁻¹². The correct answer is E.

Solubility is the measure of the degree to which a substance gets dissolved in a solvent to become a solution.

The formula for determination of molar solubity is

Ksp=[A⁺]ᵃ[B⁻]ᵇ

where

Ksp = solubility product constant

[A⁺]  = cation in an aqueous solution

[B⁻]  = anion in an aqueous solution

a, b  = relative concentrations of a and b

Data are provided as follows:

Ksp for Ag₂CrO₄ is 8 x 10⁻¹²

The solubility of silver chromate would be just half that of the Ag+ concentration.

We express Ag2CrO4's solubility as S mol L⁻¹.

Then for a saturated solution, we have

[Ag⁺]=2S

[CrO₂⁴⁻]=S

The stoichiometry of the dissolving reaction determines the relationship between the solubility and the solubility product constant.

(2S)²(S)=4S³ = 8 * 10⁻¹²

S=∛ (2*10⁻¹²)

S= 1.26 * 10⁻⁴ M

Calculate the efficiency of a simple 5 pulley machine that pulls bucket of 50 liters of water with an effort of 250N.​

Answers

Answer:

Explanation:

A machine's efficiency is a measure of how much of its input energy is turned into usable output. The following formula is used to calculate a machine's efficiency:

(Output Work / Input Work) x 100% = Efficiency

The output work in this situation is the work done by the machine to draw the bucket of water, and the input work is the effort exerted by the person running the machine.

Work produced = Force x Distance

Distance = the distance traveled by the bucket = 50 liters

As a result, the output work = 250 N x 50 L = 12500 J. (Joules)

Work input = effort x distance

Distance = the distance over which effort is exerted = 5 pulleys

So the input work is 250 N multiplied by 5 pulleys is 1250 N.

(Output Work / Input Work) x 100% = Efficiency

(12500 J / 1250 J) x 100% = Efficiency

10 × 100% Equals 1000% efficiency

It should be noted that the efficiency is expressed as a percentage and should be less than 100%. However, in this example, the answer is 1000%, which is implausible.

This might be because of an error in the input data or a misunderstanding of the situation.

A sample of aluminum (c = 0. 900 J/goC) is heated using 3,750) of energy from 20. 8°C to 38. 7°C. mass of the aluminum sample is 153.4 g.

We can use the equation Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature, to find the mass of the aluminum sample.

Given:

c = 0.900 J/gºC

Initial temperature = 20.8 °C

Final temperature = 38.7 °C

Q = 3,750 J

To use the equation, we need to convert the temperature to Kelvins.ΔT = 38.7 - 20.8 = 17.9 °C

T₁ = 20.8 + 273 = 293.8 K

T₂ = 38.7 + 273 = 311.7 K

ΔT = T₂ - T₁ = 311.7 - 293.8 = 17.9 K

Now we can plug in the values and solve for m:

Q = mcΔT

m = Q / cΔT

m = 3750 / (0.900 x 17.9)

m = 153.4 g

Ionic bonds are formed between positively and negatively charged ions and are characterized by a large difference in electronegativity between the atoms involved. The bond strength of ionic bonds is quite high. In aqueous solutions, hydrogen bonds also have a relatively high bond strength, as they are formed between a partially positively charged hydrogen atom and a partially negatively charged atom, such as oxygen or nitrogen. Hydrogen bonds are weaker than ionic bonds, but they are still relatively strong compared to other types of interactions such as dipole-dipole interactions or London dispersion forces. Hydrophobic clustering and nonpolar covalent bonds are not as strong as hydrogen or ionic bonds.
