Must write equation with format and choices given. Not just final answer. Fill in with options given. May add factors.

How many moles of Mno, are produced when 4.30 kg of oxygen gas completely reacts according to the balanced chemical reaction: 2 Mn(s) + 3 O2(g) + 2 MnO,(s) STARTING AMOUNT ADD FACTOR ANSWER RESET 6.022 x 10- 0.001 4.30 9.22 x 10 32.00 1000 2 moi Min moloz 3 89.6 0.0896 102.94 54.94 903 mol MnO, gMngMno, kg 0;

Answer 1

2 Mn(s) + 30219) 2 MnO3(s) Now, moles of O2= mass Now, moles of O2 = 4.30x103g molar mass 32 g/mol 134.38 mol By sen, 3 mol O2 react with a 2 mol Ma $134.38 mol O2 react with : 12 x 134.38) mol Mn 89.6 mol mol
