boiling point is temperaturw of liquid
The answer is B) the solutions vapor pressure will be lower.
Because so objects are denser than water and some are less dense than water
Answer:
hey, it's B
Explanation:
1 mol= 6.022×10²³ ions
0.2 mol= 0.2 × 6.022 × 10²³ ions
Manganese alone cannot be a catalyst. However, its oxides can work as a catalyst. Manganes (II, III) oxide has found some applications in certain reactions as a catalyst. These reactions are the oxidation of methane, carbon monoxide, decomposition of NO and the catalytic combustion of organic compounds.
