Web check the chemical equation to make sure it is balanced as written; Answer choices 10:6 3:4 4:3 2:3 question 2 30 seconds q. Aluminum oxide weighs 3.965 gram per cubic centimeter or 3 965 kilogram per cubic meter, i.e. Answer choices 10:6 3:4 4:3 2:3 question 2 120 seconds q. Web mole ratio = ( [combustion amount of 2nd element] / [molar mass of second element] ) / ( [combustion amount of 1st element] / [molar mass of first element] ) moreover, you can. So that every 4 al, there must be 3 o₂ in order to make. Density of aluminum oxide is equal to 3 965 kg/m³; Aluminum reacts with oxygen molecules, not atoms, to produce aluminum oxide. 4:3 an increase in pressure exerted on a liquid does not compress the liquid as much as the. Hence, the correct answer is 4:3.
Web to calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant. Web check the chemical equation to make sure it is balanced as written; There are two moles of o atoms in each mole of oxygen molecules (o2). Density of aluminum oxide is equal to 3 965 kg/m³; Web aluminium + dioxygen = ruby. So, 55 g of aluminium oxide will produce 27 g of aluminium. Aluminum oxide weighs 3.965 gram per cubic centimeter or 3 965 kilogram per cubic meter, i.e. Web theoretical yield = actual yield/percentage yield x 100. Answer choices 10:6 3:4 4:3 2:3 question 2 120 seconds q. Web answer (1 of 4): Web \[ = 1\,mole\,aluminium\] to finish off the question, we must change one mole of aluminium into a mass.
