The Percent error for ice and salt water is 94.55%. The Percent error for ice water is 100.40%.

Absolute zero is the temperature whereby a system in its balanced state contains the lowest energy that corresponds to -273.15 °C.

Using the formula for Percent error, we have:

[tex]\mathbf{percent \ error = \dfrac{|experimental \ value| - |actual \ value| }{|actual \ value|} \times 100\%}[/tex]

For ice and salt water:

[tex]\mathbf{percent \ error = \dfrac{|-14.9 -(-273.15)| }{|-273.15|} \times 100\%}[/tex]

Percent error = 94.55%

For Ice water:

[tex]\mathbf{percent \ error = \dfrac{|1.1 -(-273.15)| }{|-273.15|} \times 100\%}[/tex]

2 : 1mol→100g

1 : }50g→1/2mol

Answer:

Solution Concentration: Molarity Moles of solute in one liter of solution Used because it describes how many molecules of solute are in each liter of solution Tro: Chemistry: A Molecular Approach, 2/e 6 amount of solute (in moles) Molarity, M = amount of solution (in L) moles of solute M = L of solution or simply 4

GOOD LUCK!!

A solution has a concentration of 0.8 M and contains 15 g AgBrO3.The volume of the solution is 0.08 L.

The term molarity is defined as the number of moles of solute per litre of solution. Molarity, M = amount of solution (in L) moles of solute M = L of solution.

It is also called as molar concentration. As the number of moles of solute is measure out in mol and the volume of solution will be in litre. Hence, the unit of molarity is mol L - 1.

Given:

Molarity = 0.8 M

Mass = 15 gram

The molar mass for AgBrO3 = 235.769 g/mol.

Then calculate the number of moles in the sample by dividing the given mass by the molar mass.

15g 235.769 g/mol = 0.064 moles

Molarity = Number of moles/volume

Volume = Number of moles/Molarity

Volume = 0.064/0.8 M

Volume = 0.08 L

Thus, the volume of the solution is 0.08 L.

The statement that can be made about the samples is that each balloon contains 1 mole of each gas.

Molar volume refers to the volume that is occupied by one mole of a gas. According to Avogadro, the volume occupied by one ole of  a gas is 22.4-L at STP.

Hence, if 22.4-L at STP is the volume of both the helium and argon filled balloons, then each balloon contains one mole of the gas.

Answer:

18.01528 gram using the molecular weight calculator and the molar mass of H2O.

Explanation:

Answer:

C

Explanation:

First we have to find the molar mass of NH3 which we can do by adding the atomic masses of all the constituents. 14+3(1) = 17g/mol. Then we convert the grams of ammonia to moles. 68/17=4 moles of ammonia produced. According to the equation, one mole of nitrogen gas corresponds to two moles of ammonia, so for our 4 moles of ammonia, 2 moles of nitrogen gas were there originally. Then we convert that figure into grams using the molar mass of nitrogen gas. 2(14) = 28g/mol and 28*2=56 grams of nitrogen gas.

Answer:

Earths heat and hydrological cycle

Explanation:

Combustion is the process in which CO₂ is react with reactant. Heat of combustion of ethane is 1560 kilo joule per mole.

Combustion is the process in which oxygen is react to form heat or energy. There are three types of combustion as follows

spontaneous combustion

rapid combustion

explosive combustion

Combustion is a chemical reaction between substances, mostly including oxygen and usually followed by the generation of heat and light in the form of flame.

Combustion is the other word for burning. In a combustion reaction, a fuel is heated and it reacts with oxygen and their is energy released.. The fire triangle require the three things for combustion - a fuel, heat and oxygen.

Thus, combustion of ethane gives 1560 kilo per joule energy.

Answer:

The functional group is called a amide so its, C.

Explanation:

Reaction

8SO₂ + 16H₂S → 3S₈ + 16H₂O

find limiting reactant

mol SO₂ = 64 : 64 g/mol =  1

mol H₂S = 61.2 : 34 g/mol = 1.8

ratio mol:coefficient

SO₂= 1 : 8= 0.125

H₂S=1.8 : 16 = 0.113

H₂S as a limiting reactant (smaller ratio)

mol S₈ will be based on limiting reactant (H₂S)

mol S₈ = 3/16 x 1.8 = 0.3375

mass S₈ = 0.3375 x 256 = 86.4 g

Glaciers scraped across the surface and altered landscapes and the course of rivers best describes the impact of glaciers upon the surface of the earth.

Glaciers are the huge big bodies which are formed by the compression of fallen snow on the land and converts into the ice.

Glaciers shows movement due to the gravitational force and this movement of glaciers will carry sediments, rocks and soil with it self. So, the glacier movement will affect the land by destroy the shape of land surface due to the transfer of land materials and sometimes block the path of rivers also.

The sample's decay constant for the given time of radioactive decay is 0.0058 days⁻¹. Thus, the half life of the sample is 119.48 days.

Heavy unstable radioactive nuclei undergo radioactive decay by the emission of charged particles. They stable isotopes or new atoms by radioactive decay.

It is given that the sample of 24 grams decays to 18.8 grams within 18 days. The decay constant k can be calculated as follows:

k = 1/t log (Ci/Ct)

Where Ci is the initial amount and Ct be the final amount.

k = 1/18 log (24 g /18.8 g)

  = 0.0058  days⁻¹

Now, the half life time of the sample can be calculated as:

t1/2  = 0.693 / k

      = 0.693/0.0058  days⁻¹

      = 119.4 days.

Therefore, the half life of the sample is 119.4 days.
