Answer:
The earth rotates from West to east
Explanation:
- Every planet in our solar system rotates around their axis in West to east direction.
- Only Venus is the only planet which rotates from east to west
Answer:
Product side
Explanation:
When water vapor reacts reversibly with solid carbon to yield a mixture of hydrogen gas and carbon monoxide and we continually add more water vapor to the reaction the equilibrium of the reaction shifts to the product side.
Because gaseous water is reactant that appears in the reaction quotient expression.

When we add more water vapor to the reaction the product formation is increased. The reaction goes in forward direction affecting the equilibrium.

The law of conservation of mass states that in a closed system, the mass of the system cannot change over time. We can remember the law of conservation of mass with this simple statement: The mass of the reactants must equal the mass of the products
There are equal number of atoms on both sides.
