When a green iron salt is heated strongly its color finally changes to black and adour of burning sulfur is given out name the iron salt and write the chemical equation?
iron salt -sodium decomposition reaction don't know chemical equation
What causes a chemical change?
No, not always. For example, if you mix salt and water, no chemical change takes place. The salt dissolves in the water and a solution is formed, which is not a chemical change because the salt and water retain their individual chemical compositions.
What is that green salt on heating decomposes to produce a colorless suffocating gas and leaves behin reddish brown residue?
Ferrous sulfate gives sulfur dioxide and a mixture of iron oxides when heating.
Describe how the apperance of the green salt and cold water in the beaker change over a period of time?
Over a period of time green salt and cold water changes clear and colorless.This takes some time and is does in a process.
How can we get back salt from its solutions from science?
Evaporate the water. The salt will crystalize out. Evaporation can be accelerated by heating the solution,

Which alkaline salt swells on heating?
Ammonium Dichromate..(NH4)2Cr2O7..and leaves green residue of Cr2O3..
How can anhydrous salt changes into their hydrated salt?
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
What causes a chemical change?

What happened to the salt after heating?
Salt will just become hotter after heating, it will never melt.
What is that green salt on heating decomposes to produce a colorless suffocating gas and leaves behin reddish brown residue?
Ferrous sulfate gives sulfur dioxide and a mixture of iron oxides when heating.
Can patients have olives on a low salt diet?
In most cases, yes for black olives. However, green olives are packed in a brine that is heavy with salt, so, no for green olives.
How can you separate the water from the salt of crystallisation?
This can be done by heating the salt.
Is heating the salt solution a chemical or physical?
Heating is a physical process.
Describe how the apperance of the green salt and cold water in the beaker change over a period of time?
Over a period of time green salt and cold water changes clear and colorless.This takes some time and is does in a process.
How would you get solid salt back from salt and water mixture?
by heating
What is Difference between black and green olives?
Olives grow on olive trees in Spain, Italy, Greece, and the US. The black (ripe) olives have a stronger, more pungent taste than green olives. The reason that we don't taste the bitterness of the black olives (when we buy them in a can) is because most of the oil and flavor is taken out, when marinated in water with a slight bit of vinegar and just a very small amount of salt. The green olives that we buy in the jar are marinated in water with a bit of vinegar and lots of brine salt, and often stuffed with pimentos. The brine salt and vinegar kills the bitterness of the olives; this is why in the US when you taste green or black olives , you usually can't taste the original authentic flavor. Another difference is the curing. Olives are cured in brine (salt and water). A green olive is picked early so it remains green after curing. A black olive stays on the tree longer and is black. It is black when cured, too.
