Charle's Law states: V/T = k
where k is a constant

We can get this from the ideal gas law when pressure, and number of moles are held constant.

We can also use this and say
V₁/T₁ = k = V₂/K₂

V₁/T₁ = V₂/K₂

38.8°C = 311.95 K
-39.9°C = 233.25 K

8.89L/311.95K = V₂/233.25K

V₂ = 6.65 L

The gas will have a volume of 6.65 L at -39.9°C.

Answer:

N=2

H=6

Explanation:

1.Balance a chemical equation in terms of moles.

2.Use the balanced equation to construct conversion factors in terms of moles.

3.Calculate moles of one substance from moles of another substance using a balanced chemical equation.

The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products.

(P.s it could also be where you have to solve it in which you have to simplify it first then solve it.) like adding them all up.

Hope this is the answer. :)
