c) 2 LiBr + F2
2 LiF + Br2
Here Br gets oxidised from -1 to 0 while F gets reduced from 0 to -1. Therefore it is a redox reaction
d) This is a combustion reaction. All combustion reactions are redox reactions, where C gets oxidised due to addition of Oxygen to it while O gets reduced due to Addition of Hydrogen to from water
e) this is the right answer as we the above 2 reactions are redox

1) why is CO2 the conjugate acid of bicarbonate? Please explaing CO2 (g) + H2O(l) ⇄ H2CO3 (aq) 2) Exercise increases metabolism and thus increase the amount of CO2 in the blood. Following a bout of intense exercise, the pH of your blood was found to be 7.1 and the HCO3− concentration in the blood to be 8 mM. Remember the overall reaction for the bicarbonate buffering system in the blood can be written as: H2CO3 (aq) ⇄ HCO3- (aq)...
