what is the reactant in this equation ?2HBr(aq)+ca(OH)2(aq)-->2H2O(i)+CaBr2(aq)
u must actually be dumb to ask this question
To determine the reactant in a chemical equation, you need to identify which substances are present on the left side (reactant side) of the equation. In the given equation:
2HBr(aq) + Ca(OH)2(aq) → 2H2O(l) + CaBr2(aq)
The substances present on the left side of the arrow (HBr and Ca(OH)2) are the reactants.
To identify them, you can break down the equation:
- 2HBr(aq) represents two moles of hydrobromic acid.
- Ca(OH)2(aq) represents one mole of calcium hydroxide.
Thus, HBr and Ca(OH)2 are the reactants in this equation.
