The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants.
- +: plus sign.
- CuSO₄(aq), H₂O(l), CO₂(g): products.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.
<h3>What is a chemical equation?</h3>
It is a way to represent a chemical reaction.
Let's consider the following chemical equation.
CuCO₃(s) + H₂SO₄(aq) → CuSO₄(aq) + H₂O(l) + CO₂(g)
The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants. They are on the left side of the equation.
- +: plus sign. It separates substances.
- CuSO₄(aq), H₂O(l), CO₂(g): products. They are on the right side of the equation.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.

#SPJ1
The answer would be water , carbon dioxide and methane because they all contain more than one element.
Water-H2O
Carbon Dioxide-CO2
Methane-CH4
It would be: 1s2, 2s2, 2p6, 3s2
Answer:
Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible for us to realize that the 46.2 kJ of energy are given per mole of reaction, which are related to 3 moles of hydrogen; Thus, we can calculate the energy per mole of hydrogen as shown below:
Now, to calculate the total energy, we convert the grams to moles of hydrogen as shown below:
Best regards!
Large samples... also can be small as well but usually bigger is better
