exothermic
A balanced chemical reaction.
In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O, manganese in MnO2 is getting oxidized from +4 to +2 (in MnCl2). Chloride ions in HCl are being reduced to chlorine gas (Cl2).
The oxidizing agent in the reaction CH4 + 2O2 → CO2 + 2H2O is oxygen (O2). Oxygen is the substance that is gaining electrons and causing the methane (CH4) to oxidize.
The reaction of 2Br2 + 2H2O → 4HBr + O2 involves the oxidation of bromine (Br2) by water (H2O) to form hydrogen bromide (HBr) and oxygen (O2). Bromine is reduced to HBr, and oxygen gas is released as a byproduct.
2H2 + O2 --> 2H2O
This is an oxidation-reduction reaction.
A combustion reaction.
It is an eothermic type of reaction.
A balanced chemical reaction.
2F2 + 4NaOH >> 4NaF + O2 + 2H2O
this is an exotermic reaction
Yep
The chemical reaction is: CH4 + 2O2 --> 2H2O + CO2 CO2 is the carbon dioxide.
exothermic
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
The balanced equation for the reaction would be: 2ClO + 2HCl + C6H10O5 + 2KI → 2KCl + 2H2O + CO2 + I2.
In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O, manganese in MnO2 is getting oxidized from +4 to +2 (in MnCl2). Chloride ions in HCl are being reduced to chlorine gas (Cl2).
