Please answer all

For the following oxidation-reduction reactions, circle the reactant that is being oxidized. S_2(s) + 8 O_2 (g) rightarrow 8SO_2 (G) Ca(s) + 2 HCL (aq) rightarrow CaCl_2(aq) + H_2(g) 2Na(s) + Br_2(l) rightarrow 2NaBr(s) Cu^2+ (aq) + Zn(s) rightarrow Zn^2+ (aq) + Cu(s) 2KCIO_2 (s) rightarrow 2KCI (s) + 3O_2 (g) Use Table 4.5 to determine whether the following reactions will occur. Will Aluminum metal be oxidized by Zn^2+ (aq)? Answer: (Yes or No) Will Calcium metal be oxidized by Sr^2+ (aq)? Answer: (Yes or No) Will silver metal be oxidized by Fe^2+ (aq)? Answer: (Yes or No) Will Zinc metal react with HCl(aq) to form H2(g)? Answer: (Yes or No) Will Copper metal react with HCl(aq) to form H_2(g)? Answer: (Yes or No) What type of chemical reaction is occurring in each of the following equations? The types of reactions below are Redox reactions, Neutralization reaction, and Precipitation reaction] NaOH(aq) + HCl (aq) rightarrow NaCl (aq) + H_2O ___ 2KCIO_3 (s) rightarrow 2KCl + 3O_2 ___ 3 Cu(NO_3)_2 (aq) + 2Cr(s) rightarrow 3Cu(s) + 2Cr(NO_3)(aq) ___ Ba(NO_3)_2 (aq) + K_2 SO_4 rightarrow BaSO_4 + 2KNO_3 (aq) ___ Ca(OH)_2 (aq) + 2 HCl (aq) rightarrow CaCl_2 (aq) + H_2O (l) ___

Explanation / Answer

I am solving Q4 with five-subparts, post multiple question to get the remaining answers

Q4)

a) S8(s) + 8O2(g) -------- 8SO2(g)

Sulphur is getting oxidized from oxidation state of 0 to 4

Hence sulpur is the correct answer

b) Ca(s) + 2HCl(l) --------- CaCl2(aq) + H2(g)

Calcium is oxidize from oxidation state of 0 to 2

Hence Ca is the correct answer

c) 2Na(s) + Br(l) ------ 2NaBr(s)

Sodium is oxidize from oxidation state of 0 to 1

Hence Na is the correct answer.

d) Cu(2+) + Zn -------- Zn(+2) + Cu(s)

Zinc is oxidize from oxidation state of 0 to 2

Hence Zn is the correct answer

e) 2KClO3 ------ 2KCl + 3O2

Hence oxidation is going from oxidation state of -2 to 0

Hence O is the correct answer
