Explanation:
According to Charles law : V/T=k (constant).
the volume temperature relationship will be
V/T = 117.5/25 = 4.7
hope this helps you.
Answer:
89.6 L.
Explanation:
- For the balanced reaction:
<em>CS₂ + 3O₂ → CO₂ + 2SO₂.</em>
- It is clear that <em>1.0 mole of CS₂</em> with 3.0 moles of O₂ to produce 1.0 mole of CO₂ and <em>2.0 moles of SO₂.</em>
<em></em>
<u><em>Using cross multiplication:</em></u>
1.0 mole of CS₂ produces → 2.0 moles of SO₂.
2.0 mole of CS₂ produces → ??? moles of SO₂.
∴ The no. of moles of SO₂ produced = (2.0 mol)(2.0 mol)/(1.0 mol) = 4.0 mol.
- It is known that 1.0 mole of any gas at STP occupies 22.4 L.
<em>∴ 4.0 moles of SO₂ occupy = (4.0)(22.4 L) = 89.6 L.</em>

Answer:
3 CO₃²⁻(aq) + 2 Cr³⁺(aq) ⇒ Cr₂(CO₃)₃(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of ammonium carbonate and chromium(III) nitrate are combined.
3 (NH₄)₂CO₃(aq) + 2 Cr(NO₃)₃(aq) ⇒ 6 NH₄NO₃(aq) + Cr₂(CO₃)₃(s)
The complete ionic equation includes all the ions and insoluble species.
6 NH₄⁺(aq) + 3 CO₃²⁻(aq) + 2 Cr³⁺(aq) + 6 NO₃⁻(aq) ⇒ 6 NH₄⁺(aq) + 6 NO₃⁻(aq) + Cr₂(CO₃)₃(s)
The net ionic equation includes only the ions that participate in the reaction and the insoluble species.
3 CO₃²⁻(aq) + 2 Cr³⁺(aq) ⇒ Cr₂(CO₃)₃(s)
