Synthesize Information In a multistep process, cells can combine the reactants glucose (C6H12O6) and oxygen (O2) to form the pro

zloy xaker [14]

Answer:

Explanation:

In one of the process, energy is built up from scratch, in the other one, energy is liberated for use by an organism or body.

The first process deals with a metabolic reaction in which energy is liberated:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

In the above process, energy is liberated when glucose combines with oxygen. The waste products are carbon dioxide and water. This process liberates heat energy which can be used to do work.

In the reverse process:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This process stores energy in carbon chains as chemical energy. It is this energy that is released in the first process.

Therefore, we can see that the first process liberates energy and the reverse process stores energy.

Classify each of these soluble solutes as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. Solutes formula hydroch

matrenka [14]

Compounds which on dissolving in water gets completely dissociates into its ions are known as strong electrolytes whereas compounds which on dissolving in water gets partially dissociates into its ions are known as weak electrolytes.

Substances which gives solution on dissolving in water and do not dissociates into ions also does not conduct electric current are known as nonelectrolyte.

Hydrochloric acid, $HCl$

On adding $HCl$ (strong acid) in water, it will completely dissociates into ions ( $H^{+}$ and $Cl^{-}$ ) and thus, it is a strong electrolyte.

Sodium hydroxide, $NaOH$

On adding $NaOH$ (strong base) in water, it will completely dissociates into ions ( $Na^{+}$ and $OH^{-}$ ) and thus, it is a strong electrolyte.

Formic acid, $HCOOH$

On adding $HCOOH$ (weak acid) in water, it will partially dissociates into ions ( $H^{+}$ and $HCOO^{-}$ ) and thus, it is a weak electrolyte.

Methyl amine, $CH_3NH_2$

On adding $CH_3NH_2$ (weak base) in water, it will partially dissociates into ions ( $CH_3NH_3^{+}$ and $OH^{-}$ ) and thus, it is a weak electrolyte.

Potassium chloride, $KCl$

On adding $KCl$ in water, it will completely dissociates into ions ( $K^{+}$ and $Cl^{-}$ ) and thus, it is a strong electrolyte.

Ethanol, $C_2H_5OH$

On adding $C_2H_5OH$ in water, it will not dissociates into ions and thus, it is a nonelectrolyte.

Sucrose, $C_{12}H_{22}O_{11}$

On adding $C_{12}H_{22}O_{11}$ in water, it will not dissociates into ions and thus, it is a nonelectrolyte.
