Answer:
Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.

Answer:
See below.
Explanation:
pH = - log (H+)
So the pH of 1 x 10^-7 M solution is 7.
I'm sorry but I'm not sure about what the other units mean, so Im not sure of the answer to those.
If you convert the other units to the form 1 x 10^-n then the pH will be n.
In a neutral atom they are both equal, and their even quantities makes the atom neutral...
Subsidy
A price support is a type of subsidy. It seems that this is not given in
the choices. However, subsidy is a form of monetary or financial support which
is provided by a local or state sector. It aims to provide economic and social
stability and development. Hence, subsidy encompasses various types of support
funded by either government or non-government offices. It can be given in form
of either direct (money, incentives and etc.) or indirect (insurance,
write-offs and etc.) in procedures.
