Znc reacts with hydrochloric acid according to the equation Zn(s) + 2HCl(aq) ? Zndfaq) + H1g). What type of reaction is this? (1 point] 1) al Metathesis b) Decomposition c) Oxidation-Reduction 2) Indicate whether the following are \"True\" or \"False\" [3 points) 0 The limiting reagent (or reactant) is not completely consumed in a chemical reaction ii) The percentage yield is one hundred times the initial mass of a substance divided by the recovered mass of the substance- iii) ?is an empirical formula. 3) Is it wise to hap-hazardously mix household or other chemicals? (Yes or No) [1 point)No 4) Is it okay to weigh hot objects? (Yes or No) [1 point]
Solution
Answer 1. c) Redox Reaction.
It is because Zinc is getting oxidised, while Hydrogen atom is being reduced.
(Zinc is changing from 0 to +2 oxidation state, while H , from +1 to 0).
