It depends upon the subsance being burned. Normally, the substance would end being some sort of oxide (O2 molecule being attached to the base molecule of what is being burned).
You cant burn metal, i think you mean melt.
Metal dont usually give off a gas when its burnt. What is this for?
But if there is ifs most porberly CO2
a metal oxide
Oxygen
carbon dioxide is released carbonates react with acids
Hydrogen
Carbon Dioxide
evaporation
Oxygen is given off as a by-product os photosynthesis
hydrogen
Carbon dioxide is the gas given off. Oil also gives off the same gas when burned.
Hydrogen gas is given off when metal reacts with acid. e.g. Zn + 2HCl ------> ZnCl2 + H2
hydrogen
Carbon dioxide (CO2).
A salt is formed and hydrogen gas is given off
hydrogen
The calcium metal will react with the water to form calcium oxide and give off Hydrogen gas.
A spectrometer analyzes the light given off when an element is burned.
Hydrogen gas. (But this is not with all metals as some like gold do not react with acid)
no. the gas given off is carbon dioxide. a metal with acid gives off hydrogen.
its obvious..when an acid is reacting with a carbonate 3 things are made: Metal Salt Water Carbon Dioxide so the gas that would be given off is carbon dioxide
