a reddish brown gas is formed. Water droplets are formed on the sides of the tube.
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
it will decrease
it become ductile
Magnesium's mass increases as it becomes magnesium oxide.
When heated to a sufficiently high temperature, solid magnesium hydroxide will decompose into magnesium oxide and water: Mg(OH)2 -> MgO + H2O.
Magnesium burns brightly when heated in steam to form magnesium oxide and hydrogen. Mg(s) + H2O(g) --> MgO(s) + H2(g)
MgCO3 --(heat)--->MgO+CO2
When heated potassium nitrate decomposes to form :K O^2NO
If heated, magnesium oxide or MgO (a white powder) is formed.
if heated in air, it undergoes hudrolysis. on strong heating it forms MgO.
when formic acid is heated upto 575k it reduced to hydrogen and cabon di oxide HCOOHH2+CO2
it should be heated at 500°c
