The question is incomplete. The complete question is:
Calcium Carbide (CaC₂) is an unusual substance that contains a carbon anion (C₂²⁻). The reaction with water involves several steps that occur in rapid succession. CaC2 is a salt (notice that its name is similar to sodium chloride). When a salt dissolves in water, ions leave the crystal lattice and enter the aqueous (aq) solution. Write the relevant balanced chemical equation for the dissolution of CaC₂, in water.
Answer:
CaC₂(s) + 2H₂O(l) → Ca(OH)₂(aq) + C₂H₂(aq)
Explanation:
When a salt dissolves in water, it dissociates in its ions. In the Calcium Carbide, the cation is Ca⁺² and the anion is C₂²⁻, so the reaction is:
CaC₂(s) + 2H₂O(l) → Ca(OH)₂(aq) + C₂H₂(aq)
The base Ca(OH)₂ is soluble, so it will dissociate at Ca⁺ and OH⁻, but the C₂H₂ is stable and doesn't dissociate in the solution.
Answer:
The correct answer is : No, because there are 4 hydrogen atoms on the reactants side and 2 on the products side.
Explanation:
The given reaction equation is not balanced because:
- Number of hydrogen atoms on both sides are not equal that is 4 on reactants side and 2 on products side.
- Number of oxygen atoms on both sides are not equal that is 3 on reactants side and 2 on products side.
In a balanced chemical equation number of atoms of each elements are equal on both sides.
So, the balanced chemical equation will be:
