The pH of a solution is calculated as pH = -log[H+], where [H+] is the concentration of H+ ions. Based on the given concentration in the problem,
pH = -log(1.87 x 10^-13 M) = 12.73
Therefore, the pH of the solution is 12.73, and this implies a strongly basic solution.

Most acid precipitation results from the combination of _____ with water in the atmosphere, forming strong acids that fall with
aleksley [76]

Answer:

             Most acid precipitation results from the combination of <u>Sulfur Oxides and Nitrogen Oxides</u> with water in the atmosphere, forming strong acids that fall with rain or snow.

Explanation:

                    Acid rain is said to be that rain which contains high concentration of H⁺ ions. The main source of acid rain is the elimination of NOₓ (Nitrogen Oxides) and SOₓ (Sulfur Oxides) from different means in industries and other combustion processes on earth.

Examples:

                                 SO₂  +  H₂O     →     H₂SO₄

                                 NO₂  +  OH°    →     HNO₃

From above examples it can be seen that the sulfur and nitrogen oxides when reacted with water forms strong acids. These acids come along with rain water and causes different problems to living organisms and non living objects like buildings.

How many atoms are in two water molecules? pls and thxxxxxxxxx
arlik [135]

Answer:

A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre. one mole of water contains 6.02 x 1023 MOLECULES of water But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.Feb 12, 2003

Why is steam distillation prefered over fractional distillation for the extraction of essencial oils?​
frez [133]

Answer:

Because , the advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds. Steam distillation is useful for the purification of organic compounds, although vacuum distillation is more common

What is the difference between a pure solvent and a solution? Do they have the same physical properties?
pychu [463]

Answer:

The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.
