Answer:
It is a reactant that produces smaller amount of product.
Explanation:
" The limiting reactant is a reactant that control the amount of product in chemical reaction because of its smaller amount"
Consider the example:
2 H₂ + O₂ → 2H₂O
two moles of hydrogen react with one moles of oxygen and produces two moles of water. when we take two mole of hydrogen and two mole of oxygen than again two mole of water is produced because hydrogen is limiting reactant and one mole of oxygen left un reacted.
Identification of limiting reactant:
Calculate the number of moles of reactant.
compare it with number of moles of product with help of balance chemical equation.
identify the reactant which produces less number of moles of product.
Answer:
refractors and reflectors
Explanation:
Answer:
1. wa. Molecular form.
2. wa. Molecular form.
3. sa. Ionic form.
Explanation:
1. hydrocyanic acid
HCN is a weak acid. That means that in the following equilibrium, the molecular form (HCN(aq)) is favored, and that's how it should be written in solution.
HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)
2. hypochlorous acid
HClO is a weak acid. That means that in the following equilibrium, the molecular form (HClO(aq)) is favored, and that's how it should be written in solution.
HClO(aq) ⇄ H⁺(aq) + ClO⁻(aq)
3. hydrochloric acid
HCl is a strong acid. That means that it completely dissociates and it should be written in the ionic form (H⁺(aq) + Cl⁻(aq)) when it is in solution.
HCl(aq) → H⁺(aq) + Cl⁻(aq)
Answer:
yes it is a chemical reaction
Explanation:
because the substances combined and made something new
