4. Write and balance the chemical equation that relates to each of the following word equations: Remember that some elements exist as diatomic molecules (oxygen, nitrogen, hydrogen, halogens). a. solid zinc metal + oxygen gas → solid zinc oxide 22n(s) + O2(g) →2 Zn 06) b. HCl (aq) + magnesium hydroxide (aq) → magnesium chloride (aq) + water 2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H₂O) c. HNO3(aq) + calcium hydroxide (s)→ calcium nitrate (aq) + water 2 HNO3(aq) + Ca(OH)a(s)-> Ca(NO3)2(aq) + 2 H₂o(1)

I need help the balance chemical equation for number 4 part a, part b, and part c?

Topics: Balancing Equations ● Writing a chemical equation Practice: 1. In the reaction: 4Li (s) + O₂(g) → 2Li₂0 (s) a. what is the product? Liao(s) b. what are the reactants? Lis Stoichiometry c. what does the "(s)" after the formula of lithium oxide signify? Phase: Solid d. what is the coefficient of the lithium metal? e. in what phase is the lithium oxide? Solid 2. Define "chemical reaction". A process in which one or more substances (reactants) are changed into 1 or more other substance products). -Ionic or covalent bonds are made and/or broken, and a new substance is made 3. List the observations that are evidence of a chemical reaction: -Color Change, formation of a new phase, a new odor, a temperature chame, emission light, or appearance of flame. 4. Write and balance the chemical equation that relates to each of the following word equations: Remember that some elements exist as diatomic molecules (oxygen, nitrogen, hydrogen, halogens). a. solid zinc metal + oxygen gas → solid zinc oxide 22n(s) + O2(g) →→2 Zn 06) b. HCl (aq) + magnesium hydroxide (aq) → magnesium chloride (aq) + water 2 HCl(aq) + Mg(OH)₂(aq) → MgCl2(aq) + 2 H₂0) c. HNO3(aq) + calcium hydroxide (s)→ calcium nitrate (aq) + water 2. HNO3(92) + Ca(OH) 2 (s)->Ca(NO3)2(aq) + 2 H₂O(1)
