1.	How many grams of co2 would be produced from 2.0g of c2H4 and 5.0g of o2
Answer» Molar mass of ethene C 2 H 4 =2(12)+4(1)=28 g/mol7.0 g ethene corresponds to 28g/mol7.0g =0.25 moles 1 mole of ethene GIVES 2 moles of CO 2 .0.25 moles of ethene will GIVE 0.50 moles of CO 2 .Molar mass of CO 2 is 44 g/mol.Mass of CO 2 will be 44 g/mol × 0.50 mol= 22 gHence, option B is correct.
