First,let's assume ideal gas behavior for simplicity. This is a special case because the volumes of the two states are equal. At constant volume, we can use the Gay-Lussac equation:
P₁/T₁ = P₂/T₂
(0.8)/(127+273) = (P₂)/(27+273)
Solving for P₂,
P₂ = 0.6 atm
<em>Thus, the answer is 0.6 atm.</em>
The first step is always to figure out which formula you are going to use. Since you are given the moles, volume, temperature, and are asked for pressure, you will obviously be using the ideal gas law.
P = ?
V = 133 L
n = 1.7
R = 8.314
T = 393K
P = 41.76378496 kPa
Last step is to convert to mmHg
= 41.76378496 kPa x
= 313.2541482
= 3.1 x 10² mmHg
Answer:
(C) Decomposition reaction
Explanation:
A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more compounds or elements.
<u>in this example </u>
- 2KClO₃(s) ->2KCl (s) + 3O₂ (g)
Potassium chlorate (KClO₃) decomposed to two smaller compounds KCl and O₂ gas.
So, the right choice is (C) Decomposition reaction
Answer: the volume stays the same
