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 2AlCl3 + 3Cu 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+0₂-2ZnO

I need help me the balance chemical equwith number 3 part a, part b, and part c. 

1. Answer the following questions about the chemical equation shown below: 41=2x2 2 H₂ + O₂ → 2 H₂O a) What are the reactants? b) What is the product? Ho c) What do we call the number "2" in front of the H₂ (and H₂0)? Coefficient d) Is the reaction balanced? Yes 4 e) Why is there not a coefficient for O₂? Coefficient will be 1) it is omit f) How many hydrogen atoms are needed to produce two H₂O molecules? g) How many oxygen atoms are needed to produce two H₂O molecules? 2 h) How many hydrogen molecules are needed to produce two H₂O molecules? i) How many oxygen molecules are needed to produce two H₂O molecules? 1 j) Write the "word equation" that you would use to describe this reaction. Hydrogen Use words in a sentence, not formulas or an arrow. Ignore the coefficients. mode or water for minstead of produces ace di i Fe 2 plus Hydrogen 2. Balance the following chemical equations: a) 4Fe +30₂ → Fe₂O3 b) H₂ + Cl₂ c) Ag + H₂S → d) CH4 + O₂ →>>> e) HgO → Hg + f) Co + H₂O ● →HCI Ag2S + H₂ CO, +ệ H,O 0₂ ● H 2x2=1 C0₂O3 + H₂ 203 a cli 3.
