Is H2 plus Br2 equals 2HBr an oxidation-reduction reaction?
Yes it is.
Can the reaction FeCl2 plus Cu equals Fe plus CuCl2 occur?
No it cannot. While in theory it appears that Copper and Iron could just switch places, this can not actually take place. Iron has a higher 'reactivity' than Copper does, so in a sense; the Iron holds on too tight to the Chlorine ions for the Copper ions to switch and take its place.
What is a reaction in a balancing equation?
When an equation is balanced, the rate of the forward reaction equals the rate of the reverse reaction.
What type of reaction is cxhy equals co2 plus h2o?
Combustion reaction
What kind of reaction is nonmetal oxide plus water equals acid?
It is a hydration reaction.
What type of reaction is N2H4 plus 3O2 equals 2NO2 plus 2H2O?
This is an oxidation-reduction reaction.
Is H2 plus Br2 equals 2HBr an oxidation-reduction reaction?
Yes it is.
What is the oxidation half reaction for 2Mg O2 -- 2MgO?
Mg equals Mg2+ plus 2e-
Is 2HgO equals 2Hg plus O2 an oxidation reduction reaction?
i can't really read that reaction but! if there is an element by itself in either the reactant or the product side of the reaction QUICKLY think REDOX because the oxidation states for ANY element is 0 by themselves and when they form compounds they either oxidize or reduce to their oxidation state hope i helped

What type of chemical reaction is 2H2O equals 2H2 plus O2?
That is a balanced oxidation-reduction reaction. Hydrogen is oxidized, while chlorine is reduced.
