Answer:
0.047 %
Explanation:
Step 1: Given data
- Partial pressure of ozone (pO₃): 0.33 torr
- Total pressure of air (P): 695 torr
Step 2: Calculate the %v/v of ozone in the air
Air is a mixture of gases. We can find the %v/v of ozone (a component) in the air (mixture) using the following expression.
<em>%v/v = pO₃/P × 100%</em>
%v/v = 0.33 torr/695 torr × 100%
%v/v = 0.047 %
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
the energy required to raise one kilogram of the substance one degree
An endothermic reaction is when the energy is absorbed, while an exothermic reaction releases energy.
