Step 5: Calculate H1OH Ratios for More Extreme pH Solutions
In Step 5, you will calculate H/OH ratios for more
extreme pH solutions. Find the concentration of Htions
to OH-ions listed in Table B of your Student Guide for a
solution at a pH = 2. Then divide the H concentration by
the OH concentration. Record these concentrations and
ratio in Table C
What is the concentration of Htions at a pH = 2?
mol/L
What is the concentration of OH ions at a pH = 2?
mol/l
What is the ratio of Htions to OH-ions at a pH = 2?

answer; /// i believe the correct answer is (reactants);

voluntary muscles are controlled by the cerebellum.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
