HELP MY TEST IS TIMED: A sample of methane gas is 22.8 L at 313 Kelvin and 4.00 atm. What will its pressure be at 341 K and constant volume?

3.7 atm

4.4 atm

2.4 atm

.15 atm

option B.

Explanation:

Given,

Volume,V₁ = 22.8 L

T₁ = 313 K

P₁ = 4 atm

T₂ = 341 K

P₂ = ?

Volume is constant.

Using ideal gas law

Pressure of the tank is equal to 4.36 atm.

Hence, the correct answer is option B.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
