Suppose you mix one mole of sulfuric acid (H2SO4) with 1 mole of sodium hydroxide(NaOH).
olasank [31]

Answer & Explanation:

  • The neutralization of H₂SO₄ with NaOH is occurred according to the balanced equation:

<em>H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O,</em>

It is clear that every 1.0 mol of H₂SO₄ needs 2 mol of NaOH to be neutralized completely.

<em>So, when you mix one mole of sulfuric acid with 1 mole of sodium hydroxide, there will be an excess of sulfuric acid.</em>

<em>Thus, the pH of the solution remain below 7.</em>

Answer:

Gas to Solid

Explanation:

A condensation reaction goes from gas to solid

Condensation is a physical change which alters the physical properties of matter particularly the form and state. In a condensation reaction, a gas goes from solid to liquid.

It is the inverse of the sublimation reaction.

  • It involves the loss in energy by a gas.
  • When gases lose energy, they become pulled together by attractive forces.
  • This changes their state to solid with enough loss in energy.
