Expert Answer:
Limitations of law of constant composition-
This law is applicable in the case of isotopic elements. It is also not true if elements combine same ratio but produce different compounds.

- When lead sulphide, PbS and lead oxide, PbO, are heated together the products are lead metal and sulphur dioxide, SO2.
PbS(s) + 2PbO(s)
3Pb (l) + SO2 (g). If 14.0 g of lead oxide reacts according to the above equation, how many (a) moles of lead (b) grams of lead, (c) atoms of lead and (d) grams of sulphur dioxide are formed? (Atomic mass : Pb = 207.0, S = 32.1 ; O =16.0)
- 1) Calculate the number of Cl2 molecules and Cl atoms in 0.25 mol of Cl2 gas. 2) Molar mass of O is 16 g mol-1. What is the mass of one atom and one molecule of Oxygen?
- what is weight in 1 mole
- How to find mass percentage And molar mass
- 10 g of caco3 on reaction with 1 m hel acid
- molar mass of oxalic acid
- Please answer it 🙏🙏
- are there easy ways to calculate the empirical formula and molecular formula of a compound? if asked in NEET to finish in less than a minute?
