ven magnesia Matal is reacted with chlorine gas to form magnesium chloride as a product. Two substances are reacted to form only one substance. Here. This reaction is called les. A combination reaction depicted US MG plus steel to giving US MG seeing to for option B when baby um carbon. It is heated to form barium oxide and carbon dioxide as product here. One substance Be composed tow. Give talk substances. This reaction is called as decomposition reaction depicted us be c 03 in the presence off heat, giving us be a oh bless carbon dioxide for ocean sea when hydrocarbon styrene is combusted in here to form carbon dioxide and water. This it's called us combustion. Reaction represented us. See eight Etch eight plus 10 molecules off courtroom giving us eat seal too, plus four edge, too. For option B dime a tile Better combusted in water to give carbon dioxide and water as broader. The equation for this combustion reaction is shown us c. H. Three. Oh, see it's three nurse three or to giving us to seal two plus three h +20
