Note the equation below is not balanced. This is because the total number of atoms of each element in the reactants is not equal to the total number of atoms of each element in the products.
Ca + 2HCI -> CaCh,2 +?

Are you sure explain
Apologies for the confusion in my previous response. In order to balance the given chemical equation Ca + 2HCl -> CaCl2 + ?, we need to balance the number of atoms of each element on both the reactant and product sides.
On the reactant side:
Ca: 1 atom
H: 2 atoms
Cl: 2 atoms
On the product side:
Ca: 1 atom
H: x atoms (unknown, denoted by x)
Cl: 2 atoms
Since the number of H atoms on the reactant side is 2, and there are 2 Cl atoms on the product side, to balance the equation, the product formed must have 2 H atoms.
Therefore, the correct response is: 2
Okay so it’s 2?
Yes, that is correct. The second product that is formed in the balanced equation must have 2 hydrogen atoms. Therefore, the correct response is 2.
Are you positive
I apologize for the confusion in my responses. Let's go through the balancing of the equation one more time to ensure clarity.
Given equation: Ca + 2HCl -> CaCl2 + ?
On the reactant side:
Ca: 1 atom
H: 2 atoms
Cl: 2 atoms
On the product side:
Ca: 1 atom
H: x atoms (unknown)
Cl: 2 atoms
To balance the equation, the number of atoms of each element must be equal on both sides. Since there are 2 hydrogen atoms on the reactant side, we need to have 2 hydrogen atoms in the product formed to balance the equation.
Therefore, yes, it is confirmed that the correct response is 2. Thank you for your patience.
