Answer:
CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.
Explanation:
- It is a replacement reaction, that cations and anions are replaced with each other.
So, it gives CaSO₄ and CuCl₂.
- To balance the reaction, we apply the law of conversation of mass, that the no. of atoms in the reactants side is equal to that in the products side.
So, the balanced reaction is:
<em>CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.</em>
Diamond is not a rock it is a mineral.
An enzyme is a catalyst that helps speed up a chemical reaction.
Answer:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
Explanation:
H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq) + SO²⁻₄(aq) + H₂O(l)
A careful observation of the equation above, shows that the equation is already balanced.
To obtain the net ionic equation, we simply cancel Mg²⁺ from both side of the equation as shown below:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
Answer:
CO2 consists of one carbon atom and 2 oxygen atoms, where as C2O4 consists of 2 carbon atoms and 4 oxygen atoms. CO2 has a ration of one carbon atom to every 2 oxygen atoms and C2O4 has a ratio of 1:2 aswell
