Answer:
B. Gas formation
Explanation:
When you combine baking soda and vinegar - which I'm assuming happened to create this reaction - it forms carbon dioxide, a gas.

Answer:</h3>
78.75 K
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial pressure, P₁ = 500 torr
- Initial temperature,T₁ = 225 K
- Initial volume, V₁ = 3.3 L
- Final volume, V₂ = 2.75 L
- Final pressure, P₂ = 210 torr
We are required to calculate the new temperature, T₂
- To find the new temperature, T₂ we are going to use the combined gas law;
- According to the combined gas law;
P₁V₁/T₁ = P₂V₂/T₂
We can calculate the new temperature, T₂;
Rearranging the formula;
T₂ =(P₂V₂T₁) ÷ (P₁V₁)
= (210 torr × 2.75 L × 225 K) ÷ (500 torr × 3.3 L)
= 78.75 K
Therefore, the new volume of the sample is 78.75 K
It's very easy, it's depending mainly on converting a mathematical unit:
When 1 Cm = 0.0328084 Ft
So, we assume that:
in 1 year → it grows 3.38 Ft
So X(years)→ 0.0328084
∴X(years) = 0.0328084 * 3.38 = 0.0097 year
We have to convert this unit form years to days by:
1 year = 365 days
So, 0.0097 = X (days)
∴X(days)= 365 * 0.0097 = 3.5 days
So it will take 3.5 days to grow up
