Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.

Answer:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
Explanation:
Chemical equation:
BaCl₂ + Na₂SO₄ → BaSO₄ + NaCl
Balanced Chemical equation:
BaCl₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaCl(aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)+ 2Na⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
The Na⁺ (aq) and Cl⁻(aq) are spectator ions that's why these are not written in net ionic equation. The barium sulfate is present in solid form that's why can not be splitted into ions.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
Natural Gas
Explanation:
It is when fossil fuels like coal and other <em>natural gasses</em> are burned that greenhouse gas is emitted. Nuclear power does hold some danger if left unchecked, but does not contribute to greenhouse gasses in a significant way. Hydroelectric energy does not produce any greenhouse gasses as well. Geothermal energy is also something that does not produce greenhouse gasses and is renewable. The main reason why natural gasses are still used although they produce large numbers of dangerous gasses is because they cost much less than the other energy sources on this list.
Answer:
<h3>The answer is 3.97 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 33.7 g
volume = 8.49 mL
So we have
We have the final answer as
<h3>3.97 g/mL</h3>

Answer:
Explanation:
Assuming that the temperature does not change, you can use Boyle's law of ideal gases:
The data are:
- P₁ = 100atm
- V₁ = 5 ml
- P₂ = 1 atm
- V₂ = ?
Substitute, compute and find V₂:
