Electrons are emitted from the surface of a metal in photoelectric effect.

<h3>What is the photoelectric effect?</h3>

The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..

For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.

Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

Explanation:

The reaction given is;

TiCl4 + H2O --> TiO2 + HCl

The reaction is not balanced, upon balancing it is given as;

TiCl4 + 2H2O → TiO2 + 4HCl

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4?

From the reaction;

1 mol of TiCl4 requires 2 mol of H2O

6.50 mol of TiCl4 would require x mol of H2O

1 = 2

6.5 = x

x = 6.5 * 2 / 1 = 13.0 mol

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react?

From the equation of the reaction;

1 mol of TiCl4 reacts to form 4 mol of HCl

8.44 mol of TiCl4 reacts to form x mol of HCl

1 = 4

8.44 = x

x = 8.44 * 4 / 1 = 33.76 mol
