Answer:
D) Ba(s) + 2 HCl(aq) → BaCl2(aq) + H2(g)
Explanation:
In a redox reaction, One atom is gaining electrons (Reduction) whereas other is loosing electrons (Oxidation). In the reactions:
A) HBr(aq) + NaOH(aq) → NaBr(aq) + H2O(l)
As sodium is always +1 and Br always -1, <em>this is not a redox reaction.</em>
B) NaI(aq) + AgNO3(aq) → AgI(s) + NaNO3(aq)
Sodium is always +1 and nitrate ion is -1. <em>This is not a redox reaction</em>
C) Pb(C2H3O2)2(aq) + 2 LiBr(aq) → PbBr2(s) + 2 LiC2H3O2(aq)
Acetate ion, C2H3O2 is -1 as Br is -1, lithium is +1 and Pb +2, <em>This is not a redox reactoin</em>
<h3>D) Ba(s) + 2 HCl(aq) → BaCl2(aq) + H2(g)</h3>
Barium is 0 as Ba(s) but +1 as BaCl2. Is oxidizing
Hydrogen is +1 as HCl but 0 as H2. Is reducting.
This reaction is an oxidation-reduction reaction

Answer:
<u>(A) Plants would probably not have enough nitrogen.</u>
Explanation:
<em>According to the passage, bacteria help us digest our food and make yogurt. But it is the bacteria in the soil specifically that "Cycle nitrogen through the ecosystem, which plants rely on"</em>
