Why will a block of iron float in mercury and sink in water?
A block of iron will float in mercury due to the higher density of iron compared to mercury. In water, the iron block will sink because the density of iron is higher than that of water. The buoyant force acting on the iron block is determined by the density of the surrounding fluid.
What happens when iron III sulphate is heated?
By heating this compound is thermally dissociated: iron oxide and sulfur dioxide are obtained.
How does the movement of molecules inside a solid block of iron change as the iron is heated?
As the iron is heated, the kinetic energy of the molecules increases, causing them to vibrate more rapidly and over larger distances. This increased motion disrupts the ordered arrangement of the molecules, leading to expansion of the solid structure as the molecules move further apart.
Will a reaction occur when copper is heated with iron oxide?
Yes, a reaction will occur when copper is heated with iron oxide. The iron in iron oxide will react with the copper to form copper oxide and iron.
What happens when a little of ion powder mix with sulphur powder is being heated?
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
When iron is heated can it become a denser?
After heating iron in air iron oxides are obtained; these oxides have a lower density than iron.
How does the movement of molecule's inside a solid block of iron change as the iron is heated?
The molecules move faster
What happens when iron is added to oxygen?
Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground
Does a twelve pound iron block have the same density as a one pound iron block?
Randomly, probably not but not due to there weight but manufacturing.
How does the movement of molecules inside of a solid block of iron change as iron is heated?
As iron is heated, the movement of molecules inside the solid block of iron increases, leading to greater vibration and kinetic energy. This causes the atoms and molecules to move more freely within the lattice structure of the solid, resulting in expansion of the iron block.
What happens when diamondsodium and iron is heated?
In air all are oxydated.
Why will a block of iron float in mercury and sink in water?
A block of iron will float in mercury due to the higher density of iron compared to mercury. In water, the iron block will sink because the density of iron is higher than that of water. The buoyant force acting on the iron block is determined by the density of the surrounding fluid.
What is the density of an iron block that has a mass of 15.8 grams and a volume of 2 cubed centimeters?
The density of the iron block is 7.9 g/cm^3. This is calculated by dividing the mass (15.8 grams) by the volume (2 cm^3).
What happens to Iron III chloride when heated?
Iron III chloride undergoes thermal decomposition when heated. It loses its water molecules and breaks down into iron III oxide and hydrogen chloride gas.
What happens to iron filings and sulfur powder when heated?
When iron filings and sulfur powder are heated together, they undergo a chemical reaction to form iron sulfide. The iron sulfide produced is a compound that has different physical and chemical properties compared to iron or sulfur alone.
What happens when iron III sulphate is heated?
By heating this compound is thermally dissociated: iron oxide and sulfur dioxide are obtained.
How does the density of a 100-kg iron block compare with the density of an iron filing?
The density of iron is 7,874 kg/m3 or 7.874 g/cm3. The density of iron filing is somewhat lower depending upon how fine the filings are, but I guess more than 4000 kg/m3 or 4.0 g/cm3. The SI standard of density is measured in kg/m3. The density of a material is defined as its mass per unit volume. The density of iron does not change with the size of the sample. A bucket full of iron filings will have a lower density than the block because there will be air between the individual filings. The density of a deep pile of filings will be greater than a thin pile because the weight of the filings above compacts the filings below by pushing out some of the air. However, the density of each individual piece will still be the same as for the whole block.
