The chemical equation below is unbalanced. What is the coefficient of water when the equation is balanced? Mg(OH)_2(s) + HCl(g) rightarrow MgCl_2(s) + H_2O(l) 2 1 3 4 No coefficient would be shown. Aluminum metal and oxygen gas are produced when aluminum oxide is heated at high temperature, AlO_3(s) rightarrow Al(s) + O_2(g). Which statement concerning this chemical change is true? Aluminum and oxygen are the reactants in this reaction. This reaction is a combination reaction. Aluminum oxide is the product in this reaction. This reaction is a combustion reaction. This reaction is a decomposition reaction. Consider the chemical equation shown below. How many motes of oxygen gas are needed to react with hydrogen to form one mole of water? 2H_2(g) + O_2(g) rightarrow 2H_2O(l) 5 mol 0.5 mol 4mol 1 mol 3mol Glucose (C_6H_12O_6) is an important energy-rich compound produced by photosynthesis according to the equation below. What mass of glucose can be produced from 2.61 mol of CO_2 and the necessary water? (Molar masses of Glucose is 180. g/mol) 6CO_2(g) + 6H_2O(l) rightarrow C_6H_12O_6(l) + 6O_2(g) 0.0869 g 78.3 g 414 g 69.0 g 0.0128 g Upon mixing a clear colorless NaCl solution with a clear, colorless AgNO_3 solution according to the reaction below, a student observes a white cloudiness form. What is responsible for the cloudiness that is observed? NaCl(aq) + AgNO_3(aq) rightarrow AgCl(s) + NaNO_3(aq) NaCl AgCl NaNO_3 AgNO_3 It is impossible to tell
