Does 100g of iron turn into 100g of iron oxide?
No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form the compound.
What is the molecular mass of iron III oxide?
The molar mass of iron (III) oxide (Fe2O3) is approximately 159.69 g/mol. This is calculated by adding the atomic masses of two iron atoms and three oxygen atoms, which are 55.85 g/mol and 16.00 g/mol respectively.
What mass of nitric oxide is produced by the reaction of 3.71g of oxygen gas?
6,96 g of nitric oxide are obtained.
How much hydrogen gas is produced when steam is passed over hot iron?
When steam is passed over hot iron, the reaction produces iron oxide and hydrogen gas. The amount of hydrogen gas produced depends on the reaction conditions such as temperature, pressure, and quantity of iron. From the balanced chemical equation, for every mole of iron that reacts, one mole of hydrogen gas is produced.
Explain why the mass of a rusted nail would be greater than the mass of the nail before it rusted Assume that all the rust is still attatched to the nail?
When a nail rusts, iron in the nail reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. As a result, the overall mass of the nail increases when it rusts because the mass of the iron in the nail combines with the mass of the oxygen in the air to form iron oxide.
How many grams of iron oxide are produced from 8.00 mol of iron?
The balanced chemical equation for the formation of iron oxide is: 4 Fe + 3 O2 -> 2 Fe2O3. From the equation, we see that 4 moles of iron are required to produce 2 moles of iron oxide. Therefore, with 8.00 mol of iron, we can produce 4.00 mol of iron oxide. To find the mass of iron oxide produced, we multiply the moles of Fe2O3 by its molar mass, which is approximately 159.7 g/mol. This gives us 4.00 mol x 159.7 g/mol = 638.8 grams of iron oxide produced.
How does oxides affect airon mass?
Oxides, like rust (iron oxide), can increase the mass of iron due to the addition of oxygen atoms from the oxide molecules. This increase in mass occurs because of the combination of iron with the oxygen in the oxide.
Does 100g of iron turn into 100g of iron oxide?
No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form the compound.
When 1.187 grams of metallic oxide is reduced with excess hydrogen 1.054 grams of the metal is produced What is the metallic oxide?
The molar mass of the metal can be found by taking the difference in mass before and after reduction. The difference in mass is 0.133 grams and the molar mass of the metal is determined to be 29 grams/mol, suggesting the metallic oxide is iron (III) oxide (Fe2O3).
How much ferrous ascorbate equivalent to elemental iron?
Molar mass of Ferrous ascorbate is 408 g/mol Atomic mass of Fe is 55.8 1 mol of Ferrous ascorbate is 408 g; 55.8 g of that is Fe2+. So, 100 mg of Ferrous ascorbate will have 100x(55.8/408)=13.7 mg of elemental Fe
How do you calculate ferrous ascorbate is equivalet to elemental iron?
To determine the amount of elemental iron in ferrous ascorbate, you need to consider the molecular weight of ferrous ascorbate as well as the percentage of iron in the compound. Ferrous ascorbate consists of both iron and ascorbic acid (vitamin C), so you would need to calculate the molar mass of the compound, determine the percentage of iron by weight, and then convert this to find the equivalent amount of elemental iron present.
What is the percent of ferric oxide?
Ferric oxide often refers to iron (III) oxide, which has a chemical formula Fe2O3. The atomic mass of iron (Fe) is 55.85 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol. Therefore, the molar mass of Fe2O3 is 159.69 g/mol. To calculate the percentage composition of iron (III) oxide, divide the atomic mass of iron by the molar mass of the compound and multiply by 100. So, (2 * 55.85) / 159.69 ≈ 0.698 or 69.8% is the percent of ferric oxide.
What is the molecular mass of iron III oxide?
The molar mass of iron (III) oxide (Fe2O3) is approximately 159.69 g/mol. This is calculated by adding the atomic masses of two iron atoms and three oxygen atoms, which are 55.85 g/mol and 16.00 g/mol respectively.
Why would the mass of a rusted nail would be greater than the mass of the nail before?
The mass of a rusted nail can be greater than the mass of the nail before due to the formation of iron oxide (rust) on its surface. Iron oxide is heavier than iron, so the added weight contributes to the increase in mass. Additionally, the rust layer can trap moisture and other debris, further increasing the overall mass of the nail.
Why does the mass change if iron corrodes i.e 5.04g before and after 5.16g?
The additional mass is the amount of oxygen that has combined with iron to form iron oxide.
When an iron nail rusts what does its mass do?
The iron is reacting with other substances in the surrounding enviornment. This typically changes the iron atoms into molecules of iron oxide. Because the rust contains more atoms, the iron and now oxygen atoms, the mass of the nail increases.
Why does an iron nail gain weight on rusting?
When an iron nail rusts, it reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. This increase in mass causes the iron nail to gain weight during the rusting process.
