A1.0-gram strip of zinc is reacted with hydrochloric acid in a test tube. the unbalanced equation below represents the reaction.
zn(s) + hcl(aq) ==> h2(g) + zncl2(aq)
balance the equation in your answer booklet for the reaction of zinc and hydrochloric acid, using the smallest whole-number coefficients. [1]
zn(s) + hcl(aq) ==> h2(g) + zncl2(aq)

The balanced chemical equation for the reaction of zinc and hydrochloric acid is written below.

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Every balanced chemical equation follows law of conservation of mass.

The balanced chemical equation for the reaction of zinc and hydrochloric acid follows:

By Stoichiometry of the reaction:

1 mole of zinc metal reacts with 2 moles of aqueous hydrochloric acid to produce 1 mole of hydrogen gas and 1 mole of aqueous zinc chloride solution.

Hence, the balanced chemical equation for the reaction of zinc and hydrochloric acid is written above.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
