Answer:
Explanation:
The law of multiple proportions states that if two elements X and Y combine together to form more than one compound, then the several masses of X which chemically combine with a fixed mass of Y is in simple ratio.T
FIRST CASE ;
- Molar mass of Nitrogen gas = 28 g/mol
- Number of moles of Nitrogen gas = Mass/molar mass = 3.50/28 = 0.125 moles
- Number of moles of Oxygen gas = Mass/molar mass = 2.00/32 = 0.0625 moles
- Hence the ratio of number of moles of N2 to O2 will be 0.1295 : 0.0625 or 2:1
- Similarly for the SECOND CASE ;
- Molar mass of Nitrogen gas = 28 g/mol
- Number of moles of Nitrogen gas = Mass/molar mass = 0.875/28 = 0.03125 moles
- Number of moles of Oxygen gas = Mass/molar mass = 1/32 = 0.03125 moles
- Hence the ratio of number of moles of N2 to O2 will be 0.03125 : 0.03125 or 1:1
Neither, boiling and melting point per element varies from element to element on the periodic table. Family trends and period trends determine what kind of element each aspect is.
