A gas, often hydrogen. For example.
H2SO4 + Mg > MgSO4 + H2
Sulphuric Acid + Magnesium > Magnesium Sulphate + Hydrogen
The Hydrogen is the excess gas

Which metal and acid would react together to give off oxygen?
Most metals react with acids to give off hydrogen. Only very nonreactive metals, like gold and platinum do not react with metals. An example would be: Calcium + Hydrochloric Acid = Calcium chloride + Hydrogen gas (Ca +2 HCl = CaCl2 + H2)
Doeds acid and metal react to give off oxygen?
NO!!!! The general chemical reaction for acids and metals. is Acid + Metal = Salt + Hydrogen (NOT Oxygen). e.g. 2HCl + Zn = ZnCl2 + H2
What gas is given off when metals react with hydrochloric acid?
A gas called hydrogen is given off when most metals react with aqueous hydrochloric acid. The ease with which this happens varies: All alkali metals reacts extemely quickly and, with the possible exception of lithium, dangerously. The alkaline earth metals, except beryllium and magnesium, are similar. Most other metals dissolve more slowly and may require heating to evolve the hydrogen gas, and some metals such as copper, gold, and platinum do not react at all.
How was caesium identified?
React a small ammount with water and compare the heat given off with other alkali metals ofc if it does not react then it would be Cs
When metals react with acids which gas is given off?
hydrogen eg:Na+HCl------>NaCl+H2
Does more hydrogen get given off if metals react faster?
yes, because their is more energy in the metal
How does lithuim react with water?
it reacts then gives off gases and releases a flame.
The gas given off when magnesium reacts with acid?
Hydrogen. The same is true for when most metals react with an acid.
What colors of light do some metals give off when heated in a flame?
Calculate the density. An easy way to do it--so long as you're dealing with metals that don't react violently when wetted--is to weigh the sample then drop it in a graduated cylinder with some water in it. The weighing gives you mass, the graduated cylinder gives volume, mass divided by volume gives density.
What gas is given off when acid is added to a metal?
Hydrogen gas. (But this is not with all metals as some like gold do not react with acid)
What metals cannot displace hydrogen gas from a dilute acid?
all those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc. ^^ He is incorrect. All metals, one or another, will react with some acids to produce Hydrogen Gas. -He mentioned Copper and Silver. Silver and Copper will react with Nitric Acid giving off Hydrogen and NitroDioxide Gas. He mentioned Gold and Platinum. Gold and Platinum will react with Aqua Regia (A mixture of Hydrogen Chloride and Nitric Acid) giving off Nitric Oxide, Nitrogen Dioxide, and Hydrogen gas. All metals will react with FluoroAntimonic Acid, Xenic Acid, or any other super acid to give off hydrogen gas and other gases as well.
Does zinc react with oxygen when heated?
Zinc does react when heated. It sparks, then turns to a liquid. The reaction takes place because the zinc combines with the o2 and creates zinc oxide.
