What makes balancing redox reactions different from balancing other reactions?
A. Both the number of atoms and the amount of charge must be
balanced.
B. Redox reactions always occur in a basic solution of OH ions.
ChThe balanced equations have electrons left over as a reactant or
"product.
D. The reactions have to be broken up into half-reactions to balance.

Electrons are emitted

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
