In the reaction Cal2 (s) + Cl2 (g) CaCl2 (s) + I2 (s), what phases are the products in after the reaction? A. CaCl2 is a liquid, and l2 is a gas.
B. Cal2 is a solid, and CaCl2 is in aqueous solution.
C. Both products are liquids.
D. Both products are solids.

D. Both products are solids.

Explanation:

The equation for the reaction is given below:

Cal2(s) + Cl2(g) —> CaCl2(s) + I2(s)

A careful observation of the equation, shows that the products are in the following phase:

CaCl2 is in solid state.

I2 is in solid state.

From the above we can see clearly that both products are in solid state.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
