Use the following balanced equation to answer the questions below.
Blababa [14]

Answer:

A. 4.5 mol Mg(OH)₂

B. 6 mol NaOH

Explanation:

Let's consider the following balanced equation.

Mg(NO₃)₂ + 2 NaOH ⇒ Mg(OH)₂ + 2 NaNO₃

PART A

The molar ratio of NaOH to Mg(OH)₂ is 2:1. The moles of Mg(OH)₂ produced from 9 moles of NaOH are:

9 mol NaOH × 1 mol Mg(OH)₂/2 mol NaOH = 4.5 mol Mg(OH)₂

PART B

The molar ratio of NaOH to NaNO₃ is 2:2. The moles of NaOH needed to produce 6 moles of NaNO₃ are:

6 mol NaNO₃ × 2 mol NaOH/2 mol NaNO₃ = 6 mol NaOH

In an electric motor, the energy transformation that is involve is a move from from electrical energy to mechanical energy.

For every system, according to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".

  • An electric motor converts electrical energy to mechanical energy
  • The electrical energy passes through and electromagnet set up.
  • This then cause the motion to rotate.
  • Therefore, electrical energy is transformed to mechanical energy.
