Answer:
E) All of these descriptions are true
Aqueous nitric acid and aqueous ammonia reacts to form ammonium nitrate
HNO₃(aq)+NH₃(aq) = NH₄NO₃(aq)
HNO₃ +NH3 = NH₄ (+) + NO₃ (-)
Therefore the net ionic equation will be;
H⁺(aq) + NH₃ = NH₄⁺ (aq)
Answer:
D. The data supported the hypothesis
Explanation:
The data shows that rats fed a normal diet with the addition of vitamins gained a higher average weight gain in the period of 3 months, compared to rats fed a normal diet. This supports the scientists' hypothesis of "Young rats that had vitamins added to their food would gain weight faster than young rats fed a normal diet."
