Balance the following chemical equation
ratelena [41]

Answer:

Explanation:

4). Ca(NO₃)₂ + Na₂SO₄ → CaSO₄ + 2Na(NO₃)₂

  This question is incorrect.

  Since, the final product by reacting Na⁺⁺ and NO₃⁻⁻ is NaNO₃

  Correct equation will be,

  Ca(NO₃)₂ + Na₂SO₄ → CaSO₄ + 2NaNO₃

  This equation is in the balanced form.

5). Ni(NO₃)₂ + KI → NiI + 2K(NO₃)₂

  Correct equation will be,

  Ni(NO₃)₂ + KI → NiI₂ + 2KNO₃

  [Since final product by reacting Ni⁺⁺ and I⁻ is NiI₂]

  Balanced form of this equation will be,

  Ni(NO₃)₂ + 2KI → NiI₂ + 2KNO₃

6). Ni(NO₃)₂ + KOH → NiOH + K(NO₃)₂

   Correct form of the equation will be

   Ni(NO₃)₂ + KOH → Ni(OH)₂ + KNO₃

   [Since reaction of Ni⁺⁺ and OH⁻ gives Ni(OH)₂ and the reaction of K⁺ and NO₃⁻ gives KNO₃]

   Now balancing this equation,

   Ni(NO₃)₂ + KOH → Ni(OH)₂ + 2KNO₃

                              ↓

  Ni(NO₃)₂ + 2KOH → Ni(OH)₂ + 2KNO₃

If a substance contains a hydrogen ion concentration of 1.0 x 10-5 M, which types of ions does it contain more of?
miss Akunina [59]

Since the pH of the substance is 5, the substance contains more of hydrogen ions.

<h3>What is pH of a solution?</h3>

The pH of a a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution.

pH = -log[H^{+}]

A neural solution has pH 7.

A solution with pH below 7 has more hydrogen ions while a solution with pH above 7 has more hydroxide ions.

The pH of a substance contains a hydrogen ion concentration of 1.0 x 10-5 M is 5.

Therefore, the substance contains more of hydrogen ions.
