A student enters the lab and performs Experiment 14 as written. In the procedure for "Experiment 1" on p. 230 of the lab manual, the student records the concentration of the stock solution of H2O2 to be 0.965 M. The student proceeds to prepare the reaction solution as stated in the lab manual: They add 10.0 mL of 0.10 M potassium iodide and 15.0 mL of distilled water to their flask. They then add 5.0 mL of the stock H2O2 solution and mix the solution to initiate the reaction. Calculate the molarity of H2O2 in the initial reaction solution. Do not include the units with your answer.

Molarity = 0.193

Explanation:

Molarity = Gram mole of solute ÷ liters of the solution

H2O2 is the solute

The mixture of Potassium iodide and water are the solution

STEP 1: FIND THE MOLE OF SOLUTE;

Concentration of solute = 0.965M

Volume of solute = 5.0mL= 0.005L

Concentration= mole ÷ volume

Therefore

Mole = concentration × volume

Mole = 0.965 × 0.005 = 0.004825mol

STEP2: FIND VOLUME OF SOLUTION;

10.0 mL of potassium iodide + 15.0 mL of distilled water

Therefore;

10mL + 15mL= 25mL = 0.025L

STEP 3: FIND THE MOLARITY;

Molarity = 0.004825 ÷ 0.025 = 0.193

Therefore the Molarity of H202 is

0.193

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
