22.00 g of CO2 has a volume of 50.00 L and a pressure of 0.8210 atm. What must be the
creativ13 [48]

Answer:

T = 9.875K

Explanation:

The ideal gas Law is PV = nRT.

P = Pressure

V = Volume

n = amount of substance

R =  8.314 J/(K. mol)

T = Temperature in Kelvin

22g CO2

CO2 Molar Mass = 44g/mol

C = 12g/mol

O = 16g/mol

P = 0.8210atm

V = 50L

PV = nRT

0.8210 x 50 = 8.314 x 0.5 x T

41.05 =  4.157T

T = 41.05/4.157

T = 9.875K

The energy changes in chemical reactions occurs when atoms _____ to form new substances.
Zanzabum

A chemical reaction is marked by new substance formation. The energy changes in chemical reactions occur when atoms <u>rearrange</u> to form new substances.

<h3>What is a chemical reaction?</h3>

A chemical reaction is said to be the process that is characterized by the formation of new substances by the alteration of the chemical composition and the properties of the compound or the molecule.

The reaction results in a new product by the rearrangement of the atoms of the reactant molecule by breaking and creating chemical bonds. The bonds are altered by the change in energy.

Therefore, <u>rearrangement </u>is the correct blank.

A sample of a gas has a volume of 852 mL at 298 K. If the gas is cooled to 200K, what would the new volume be?
Colt1911 [192]

Answer:

571.81 mL

Explanation:

Assuming constant pressure, we can solve this problem by using <em>Charles' law</em>, which states that at constant pressure:

  • V₁T₂=V₂T₁

Where in this case:

  • V₁ = 852 mL
  • T₂ = 200 K
  • V₂ = ?
  • T₁ = 298 K

We <u>input the data</u>:

  • 852 mL * 200 K = V₂ * 298 K

And <u>solve for V₂</u>:

  • V₂ = 571.81 mL

The new volume would be 571.81 mL.
