<h3>Answer:</h3>

Higher or lower pH affect the structure of the enzyme and reduces the enzyme activity.

<h3>Explanation:</h3>
  • Enzymes are biological molecules that speed up the rate of chemical reactions.
  • Enzyme activity is affected by several factors which include temperature, pH, and enzyme inhibitors.
  • Enzymes work on specific molecules known as substrates. They are substrate-specific.
  • Enzymes work best at optimum pH and temperature.
  • Higher or lower pH affects the structure and charges of an enzyme thus affecting enzyme activity.
  • Lower temperature deactivates the enzymes while higher temperatures denature the enzymes.

Which pair of substances would most likely result in the production of a gas when reacting with an acid?
vovangra [49]

Answer: metal and carbonate

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydrogen ions (H^+) in water.

An acid is represented as :

HX\rightarrow H^++X^-

1. When metal is treated with an acid such as HCl, if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.

M+xHCl(aq)\rightarrow MCl_x(aq)+xH_2(g)

2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.

MCO_3(aq)+xHCl(aq)\rightarrow MCl_x(aq)+xH_2O(l)+CO_2(g)
