1. For the reaction 4K + O2 → 2K2O, if 1.52 moles of potassium reacts, the number of moles of potassium oxide (K2O) formed can be calculated usingstoichiometry.2. In the reaction 2Cu + 5S → Cu2S, if 0.25 moles of copper(II) sulfide is produced, the number of moles of copper needed can be determined using stoichiometry.3. Considering the unbalanced reaction Na + H2SO4 → Na2SO4 + H2O, to produce 3.75 moles of sodium sulfate, the number of moles of sodium required can be calculated.4. In the unbalanced reaction Fe2O3 + Ca3(PO4)2 → FePO4 + CaO, if 1.6 moles of iron(III) oxide reacts, the number of moles of calcium oxide produced can be determined.5. Given the decomposition of magnesium chlorate (Mg(ClO3)2) into magnesium chloride (MgCl2) and oxygen (O2), the number of moles of oxygen produced from 5.12 moles of magnesium chlorate can be calculated.6. When chromium reacts with lead(IV) nitrate (Pb(NO3)4) to produce chromium(III) nitrate (Cr(NO3)3) and lead (Pb), the number of moles of chromium(III) nitrate formed can be determined using stoichiometry.To solve each problem, we need to balance the givenchemical equationsand apply stoichiometry, which relates the moles of reactants and products based on their coefficients. By comparing the coefficients of the balanced equation, we can establish mole ratios and use them to calculate the desired quantities.For example, in problem 1, the balanced equation is 4K + O2 → 2K2O. Thecoefficient ratiotells us that 4 moles of potassium react with 1 mole of oxygen to produce 2 moles of potassium oxide. Given that 1.52 moles of potassium are reacted, we can set up a proportion to find the corresponding moles of potassium oxide.Similarly, the remaining problems involve balancing the equations, establishing mole ratios, and applying stoichiometry to calculate the desired quantities. The main steps involve identifying the balanced equation, determining themole ratios, and setting up and solving proportions or conversions using the given quantities.By following these steps for each problem, the required moles of the specified substances can be calculated accurately.To know more aboutstoichiometryclick here:brainly.com/question/28780091#SPJ11...
