It does not decrease in mass, only weight, the mass is still all there, but as when it has been heated smoke is given off from the element, and goes into the atmosphere. It may not sound like the mass is all there with the heated element, but if the smoke were conserved during the experiment the weight would be the same as before the experiment.

If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
What happens to the mass of magnesium when heated?
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide. The total mass remains the same since no mass is lost or gained during a chemical reaction.
What is the mass of 0.3 moles of magnesium sulfate?
The molar mass of magnesium sulfate (MgSO₄) is approximately 120.37 g/mol. To find the mass of 0.3 moles, you multiply the number of moles by the molar mass: 0.3 moles × 120.37 g/mol = 36.11 grams. Therefore, the mass of 0.3 moles of magnesium sulfate is about 36.11 grams.
What is the percent composition of magnesium sulfate in magnesium sulfate heptahydrate?
51.1%
When 24g of magnesium metal is heated in air 40g of magnesium oxide is produced. What mass of magnesium would be needed in order to produce 10g of magnesium oxide?
6g
If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
What happens to the mass of magnesium when heated?
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide. The total mass remains the same since no mass is lost or gained during a chemical reaction.
What happens to the mass when magnesium is heated in air?
When magnesium is heated in air, it reacts with oxygen to form magnesium oxide. The total mass of the system, which includes the magnesium and the oxygen it reacts with, remains the same according to the Law of Conservation of Mass.
What is the mass of 0.3 moles of magnesium sulfate?
The molar mass of magnesium sulfate (MgSO₄) is approximately 120.37 g/mol. To find the mass of 0.3 moles, you multiply the number of moles by the molar mass: 0.3 moles × 120.37 g/mol = 36.11 grams. Therefore, the mass of 0.3 moles of magnesium sulfate is about 36.11 grams.
How many moles are present in 480g of anhydrous magnesium sulfate?
First we calculate the formula mass of the compound magnesium sulfate.Formula mass of MgSO4 = 24.3 + 32.1 + 4(16.0) = 120.4 Amount of MgSO4 in a 480g pure sample = 480/120.4 = 3.99mol There is approximately 4 moles of the compound present in a 480g sample.
When 84G of magnesium carbonate was heated 40G of magnesium oxide was collected why did the mas go down?
The decrease in mass is likely due to the release of carbon dioxide gas during the process of heating magnesium carbonate to form magnesium oxide. The gas escapes, leading to a decrease in the overall mass of the sample.
What is wrong with this word equation calcium chloride plus magnesium sulfate barium chloride plus magnesium sulfate?
This word equation is incorrect because it does not follow the law of conservation of mass. The equation should be: calcium chloride plus magnesium sulfate yields barium sulfate plus magnesium chloride.
What is the percent composition of magnesium sulfate in magnesium sulfate heptahydrate?
51.1%
Does hydrated copper sulphate increase the mass?
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
Do MgSO4 and NaCl weigh the same?
No Magnesium Sulfate (MgSO4) has a mass of 121, and Sodium Chloride (NaCl) has a mass of 59.
If a 2.743 g sample of magnesium sulphate crystals was heated strongly what would be the mass of the cooled dehydrated salt?
The mass of the cooled dehydrated salt would be less than 2.743 g because heating would remove water molecules, decreasing the overall mass. The exact mass would depend on the percentage of water lost during heating.
When 24g of magnesium metal is heated in air 40g of magnesium oxide is produced. What mass of magnesium would be needed in order to produce 10g of magnesium oxide?
6g
