The molecular mass of carbon monoxide (CO) is 28 g/mol
<u><em>calculation</em></u>
The molecular mass of CO = atomic mass of C + atomic mass of O
From periodic table the atomic mass of C = 12 g/mol and for O = 16 g/mol
Therefore the molecular mass of Co = 12 g/mol + 16 g/mol = 28 g/mol
To be honest it have to be c because it shows things
Silver is not a compound. It's a mixture
Answer:
This question is incomplete
Explanation:
This question is incomplete, however it can be concluded that this question is testing concepts about equilibrium within a chemical reaction.
It is a rule that:
If a reactant is added, the forward reaction will be favored.
If a product is added, the reverse reaction will be favored.
The same principle can be applied if a reactant/product is taken away. The reaction will try and produce more of what is not there, and this will shift the equilibrium.
Answer:
Option C = They must have same average kinetic energy.
Explanation:
According to the kinetic molecular theory,
1. The kinetic energy of gas molecules is only depend upon the temperature.
2. The gas molecules are randomly moves in any direction and thus colloid with each other and wall of container. This collision is elastic.
3. The volume of gas particles is negligible as compared to the volume of container.
4. The ideal gas does not exhibit attractive and repulsive forces.
The first postulate of kinetic molecular theory state that the average kinetic energy is depend upon the temperature so at the same temperature and pressure the two different gases have same kinetic energy.
