Cbse Class 11 Ncert Book Chemistry Part 1 Some Basic Ans: the balanced equation for the combustion of carbon in dioxygen air is. (i) c o 2 = co 2. 1 mole of carbon burnt in air will produce 44 grams of co₂. (ii) 1 mole of carbon is burnt in 16g of dioxygen. 16g of dioxygen corresponds to 16 32 = 0.5 moles. i.e., dioxygen is the limiting reactant. Some basic concepts of chemistry 3 a number of classical texts, like atharvaveda (1000 bce) mention some dye stuff, the material used were turmeric, madder, sunflower, orpiment, cochineal and lac. some other substances having tinting property were kamplcica,pattanga and jatuka. varähmihir’s brihat samhita gives. Solution: molecular mass of na 2 so 4 = 2 × atomic mass of na atomic mass of s 4 × atomic mass of o. = 2 × 23 32 4 × 16 = 46 32 64 = 142 u. question 3. determine the empirical formula of an oxide of iron which has 69.9% iron and 30.1% oxygen by mass. solution: hence, the empirical formula is fe 2 co 3.
