Why when iron is heated with sulphur iron sulphide is formed the total mass of iron and sulphur is equal to the mass of iron sulphide?
According to John Dalton matter can neither be created nor destroyed in a chemical reaction. The law of conservation ofass given by A Lavoisier suggest that total mass of products is equal to the the total mass of reactants .In other words there is no change in mass during a chemical reaction.

When iron is heated with sulferiron sulphide is formed the total mass of iron and sulferis equal to the mass of iron sulphide?
Yes. This is an example of the law of conservation of matter/mass.
What does Sulfur plus Oxygen equal?
Sulphur + oxygen = Sulphur Oxide
How much magnesium sulphide can be made from 1.0gram of magnesium and 1.0gram of sulphur?
The formula of magnesium sulphide is MgS, showing that a formula unit has one atom of each element. The gram atomic mass of magnesium is 24.305 and that of sulphur is 32.06. Therefore, when magnesium and sulphur are present in equal amounts by mass, sulphur is the limiting reactant. 1.0/32.06 or 0.031 moles of sulphur atoms are present. Therefore, the maximum amount of MgS that can result from reaction is 0.031 formula units of MgS. The gram formula mass of MgS is 56.365, so that 0.031 formula units of MgS will have a mass of 1.7 grams, to the justified number of significant digits.
5 moles of sulphur?
5 moles of sulfur is equal to 160,3 g.
When a mixture of iron and sulfur is heated a compound called iron sulfide is madein an experiment 2.8g of iron made 4.4g of iron sulfide What mass of sulfur reacted with the 2.8g of iron?
3.2g ..... assuming it is iron (II) Sulphide FeS2. The relative atomic mass of iron is 56, sulphur is 32, so the ratio of masses of these two elements IN THE FORMULA = 56 : 64. If 2.8g of iron was used then, from the ratio, this will react with 3.2g of sulphur.
Why does the mass of copper oxide not lose mass when heated?
When copper oxide is heated, it undergoes a chemical reaction that causes it to lose oxygen atoms, resulting in the formation of copper metal. The mass of the copper metal formed is equal to the mass of the original copper oxide. Therefore, the overall mass remains the same.
