I need help with number 2. I need help with the balanced chemical equation for parts a, part b, part c, part d, part e, and part f (the balance chemical equation).

2. Balance the following chemical equations: for water for minstead of produce 1 Fe 2 a) Fe +30₂ b) H₂ + Cl₂ c) Ag + H₂S → Ag₂S + H₂ d) CH4 + O₂ ->> f) Co + H₂O Fe₂O3 e) HgO → Hg + 0₂ ● НСІ ● 6=3x2 0 CO2 + a 3x2=6 2 Н 1-ха 2 C1 1x2=2 coefficient of 2 in front of Hel 2= 2 x1 Ag 2 24 2 H2O ICI 42x2=4 coefficient of 2 in front of both ₂ and Han 2×1Hg 1x2=2 2 22x102 coefficient of 2 in front of H₂0 and 02 → Co₂O3 + H₂ 2=2×102 £= 3 x2 # 2x3=6 3=3x10 3 x1=3 3. Write balanced chemical equations for each of the following descriptions of a chemical reaction. You do not need to include the phases of the reactants or products. IMPORTANT NOTE: Before attempting to balance the equations, you must first convert the compound names into the correct chemical formulas. If you begin to struggle with that, you may wish to go back to Chapter 3 and re-work the naming problems. a) Aluminum metal reacts with copper(II) chloride to produce aluminum chloride and copper metal. 2 Alt 3cucla -2 AICI 3+3 Cu 1 AI F 1 Cu 4 2 cl 3 b) Lead(II) nitrate reacts with sodium bromide to produce lead(II) bromide and sodium nitrate. HINT: Since you have the same polyatomic ion (nitrate) on both sides of the equation you can use the shortcut that was listed in Step #1 of our balancing method. Pb(NO3)2 + 2 Na Br-7 Pb Bra + 2 NaNO3 c) Zinc metal reacts with oxygen gas to produce zinc oxide (Recall that oxygen is one of the diatomic molecules that are referred to by their element's name). 22n+0₂->22nO 1 2 Zn 1 01x2 = 2
