How much oxygen is required for complete combustion of 560 g of ethene...
28 g of C2H4 requires 96 g of O2
560 g of C2H4 requires 96/28 x 560
= 1920 g or 1.92 kg of O2

How much oxygen is required for complete combustion of 560 g of ethene...
To solve this problem, we need to balance the chemical equation for the combustion of ethene:
C2H4 + O2 → CO2 + H2O
From the balanced equation, we can see that 1 mole of ethene reacts with 3 moles of oxygen to produce 2 moles of carbon dioxide and 2 moles of water.
First, we need to find the number of moles of ethene in 560 g.
Molar mass of ethene (C2H4) = 2(12.01) + 4(1.01) = 28.05 g/mol
Number of moles of ethene = 560 g / 28.05 g/mol = 19.96 mol
Next, we can use the stoichiometry of the balanced equation to find the number of moles of oxygen required.
1 mol C2H4 requires 3 mol O2
19.96 mol C2H4 requires 3 x 19.96 mol O2 = 59.88 mol O2
Finally, we can convert the number of moles of oxygen to mass.
Molar mass of oxygen (O2) = 2(16.00) = 32.00 g/mol
Mass of oxygen required = 59.88 mol O2 x 32.00 g/mol = 1916.16 g = 1.92 kg
Therefore, the correct answer is option B, 1.92 kg of oxygen is required for complete combustion of 560 g of ethene.
C2H4 + O2 → CO2 + H2O
From the balanced equation, we can see that 1 mole of ethene reacts with 3 moles of oxygen to produce 2 moles of carbon dioxide and 2 moles of water.
First, we need to find the number of moles of ethene in 560 g.
Molar mass of ethene (C2H4) = 2(12.01) + 4(1.01) = 28.05 g/mol
Number of moles of ethene = 560 g / 28.05 g/mol = 19.96 mol
Next, we can use the stoichiometry of the balanced equation to find the number of moles of oxygen required.
1 mol C2H4 requires 3 mol O2
19.96 mol C2H4 requires 3 x 19.96 mol O2 = 59.88 mol O2
Finally, we can convert the number of moles of oxygen to mass.
Molar mass of oxygen (O2) = 2(16.00) = 32.00 g/mol
Mass of oxygen required = 59.88 mol O2 x 32.00 g/mol = 1916.16 g = 1.92 kg
Therefore, the correct answer is option B, 1.92 kg of oxygen is required for complete combustion of 560 g of ethene.
