Answer:
homogenous is a uniform and consistent mixture ; heterogenous is a mixture that is non-uniform
Explanation:
usually if you can separate the mixture/particles it is heterogenous. For example, pizza is heterogenous because you can separate the dough from the tomato sauce from the cheese. vinegar is homogenous (cannot separate mixture)

Answer:
8
Explanation:
Oxidation:

Reduction:

We have to equalise the number of moles of electrons gained and lost in a redox reaction in order to get a balanced reaction.
Hence we have to multiply the oxidation reaction throughout by 6.
and adding the two half-reactions we obtain:

Still the total charge and number of oxygen is not balanced.
Since the reaction takes place in acidic conditions, we will add required number of H+ to the appropriate side to balance the charge and add half the amount of H2O to balance the hydrogen atoms.
We add 14 H+ on LHS and 7H2O on RHS to obtain:

Sum of coefficients of product cations = 6+2 = 8
Matter can only me transformed, but not created or destroyed.
