Concept introduction:
The process in which the reactants combine to form a new product is called a chemical reaction. A chemical reaction can be represented using a chemical equation. A balanced equation is the one where the number of atoms of each element is equal on both sides of the equation.

(pKa HClO = 7.46) A. 7.31 B. 7.46 C. 7.61 D. 10.44arrow_forwardWhy is carbon dioxide CO2 able to be stored more effectively in ocean water vs. fresh water a. The pH of the ocean is very low and so the carbon dioxide is trapped as an acid because like dissolves like. b. Gases are more soluble in cold water than warm water and the oceans are colder than fresh water lakes so you can dissolve more CO2 in them. c. The pH of the ocean is pretty high and so the carbon dioxide is trapped in a neutralization reaction. d. The oceans are large and so you can dissolve more CO2 in them.arrow_forwardds # 3 80 16. What is buffer capacity? a. The maximum amount of H+ or OH- ions that a buffer can absorb without a significant change in pH. b. The reaction of an acid with a base to produce water and a salt. c.
