Express your answer with the appropriate units. » Hints The coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. The molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. ! uà 1 + 0 = ?

Write a complete balanced equation for the synthesis reaction, including phase descriptors, and use it to answer the following questions i. How many moles of potassium chloride would react with 8.56 moles of oxygen? How many moles of potassium chlorate would this produce? a. ii. How many moles of potassium chlorate are produced from 34.21 g oxygen? ii. What mass of potassium chloride is needed to produce 93.45 g potassium chlorate? iv. How many molecules of O2 are needed to produce 0.473 g potassium chlorate? Start by identifyjing reactants and products) and writing the skeleton (unbalanced) equation. Reactant 1: ( ) Reactant 2: Product: ( ) Now balance your equation. With your balanced equation, you now have all the mole ratios you will need to solve this problem. Yo may also need to use the molar masses of all these compounds, so let's figure those out now. Potassium chloride: g/mol Oxygen: g/mol
