A chemist uses 0.25 L of 2.00 M H2SO4 to completely neutralize a 2.00 L of solution of NaOH. The balanced chemical equation of t
Mrac [35]
The balanced equation of NaOH and H2SO4 would be:

2NaOH + H2SO4 = Na2SO4 + 2H2O

To determine the concentration of NaOH, we first find the moles of NaOH used in the reaction. We start with the the concentration and volume of H2SO4. We do as follows:

2.00 M H2SO4 ( 0.25 L ) = 0.5 mol H2SO4

0.5 mol H2SO4 ( 2 mol NaOH / 1 mol H2SO4) = 1 mol NaOH

Molarity = 1 mol NaOH / 2.00 L NaOH solution = 0.5 M NaOH solution

nikitadnepr [17]

Answer:

The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.
