According to Boyle's law, what would happen to the pressure of a gas if the temperature were tripled as the number of moles and

raketka [301]

According to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple (option C).

<h3>What is Boyle's law?</h3>

Boyle's law is the observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.

However, when the temperature of a gas is increased, the pressure of the gas also increases provided the volume is constant.

According to this question, the temperature of a gas tripled as the number of moles and the volume were held constant.

Therefore, according to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple.

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
