<u>Answer:</u> The partial pressure of carbon dioxide at equilibrium is 0.0056 atm
<u>Explanation:</u>
The given chemical equation follows:

<u>Initial:</u> 4.00
<u>At eqllm:</u> 4.00-2x x x
The expression of
for above reaction follows:

The partial pressure of pure solids and liquids are taken as 1 in the equilibrium constant expression.
We are given:

Putting values in above expression, we get:

Neglecting the value of x = 718.28 because equilibrium pressure cannot be greater than initial pressure
Partial pressure of
= 0.0056 atm
Hence, the partial pressure of carbon dioxide at equilibrium is 0.0056 atm
Answer:
it is false Sodium acetate NEVER precipitates
Answer
A. molecules
Explanation
When atoms or elements combine, they are called molecules. When molecules combine they form compounds.
