6. A chemist combines 16.7 g of zinc sulfide, ZnS, with 6.70 g of oxygen, 0,, according to the following reaction: ZnS,, + ZnO, + SOn A) Balance the above equation. B) Identify the limiting reagent. C) How Many more grams of the limiting reactant are required to react with the remaining excess reacting?

Consider the generic chemical equation: 2 A + 4 B = 3 C What is the limiting reactant when each of the initial quantities of A and B are allowed to react? 1.) 2 mol A; 5 mol B 2.) 3 mol A; 4 mol B

Calculate the theoretical yield when 10.7g of lithium and 10.7g of nitrogen combine to form lithium nitride, a component of advanced batteries, according to the following unbalanced equation? Li + N2 -> Li3N

For the following reaction,0.118 moles of iron are mixed with 0.104 moles ofchlorine gas.   What is the formula for the limiting reagent? What is the maximum amount of iron(III) chloride that can be produced? moles

Alkali metal hydroxides are sometimes used to "scrub" excess carbon dioxide from the air in closed spaces (like submarines and spacecraft). For example, lithium hydroxide reacts with carbon dioxide according to the following unbalanced chemical equation: Suppose a lithium hydroxide canister contains 180. g of . What mass of will the canister be able to absorb? Mass = g If it is found that after 24 hours of use the canister has absorbed 120. g of carbon dioxide, what percentage of its capacity has been reached? Percentage = %
