Zinc sulfide reacts with oxygen according to the reaction: 2ZnS(s)+3O2(g)→2ZnO(s)+2SO2(g) A reaction mixture initially contains 4.8 mol ZnS and 7.5 molO2. Part A Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant is left?
Zinc sulfide reacts with oxygen according to the reaction: 2ZnS(s)+3O2(g)→2ZnO(s)+2SO2(g) A reaction mixture initially contains 4.6 mol ZnS and 9.4 mol O2. Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant remains? Express your answer using two significant figures.
Zinc sulfide reacts with oxygen according to the reaction: 2ZnS(s)+3O2(g)→2ZnO(s)+2SO2(g) A reaction mixture initially contains 3.4 mol ZnS and 7.5 mol O2. Part A Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant remains? Express your answer using two significant figures.
For the reaction l2(g) → 12(s), AH °= -62.4 kJ at 25°C. Based on these data, at 25°C O AH vap = 62.4 kJ/mol. O AH sub = -62.4 kJ/mol. O AH vap = -62.4 kJ/mol. O AH sub = 62.4 kJ/mol.
