Question

I need help with number 4. I need help with the balanced chemical equation for parts a, part b, and part c. The balance chemical equation is the one in which the number of atoms in the reactant and product side is equal for parts 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? Li(5) Oo (3) Atom a reactant 1 ● e. in what phase is the lithium oxide? Solia c. what does the "(s)" after the formula of lithium oxide signify? Phase: Solid d. what is the coefficient of the lithium metal? Stoichiometry Molecule Atom in product 2 Li 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) HNO 1 2 2n b. HCl (aq) + magnesium hydroxide (aq) → magnesium chloride (aq) + water 2 HCl(aq) + Mg(OH)2(ar) → MgCl2(aq) + 2 H₂0) 1 H CI Mg c. HNO3(aq) + calcium hydroxide (s) → calcium nitrate (aq) + water 2 HNO3 (12) + Ca(OH)2 (s)-> (a (NO₂)2(aq) + 2 H₂O(1)
