No. A voltage reading is a result of a difference in cell potential of the cells. Even if you added the volume, it would still not affect because what matters is the concentration of the ions which give the potential gradient. All you did was add the quantity in terms of volume but the substance in it is still the same.

c) : = +ve
d) : = +ve
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
a)
As solid is moving to ions form , randomness increases and thus sign of is positive.
b)
As gaseous reactants are converted to solid products , randomness decreases and thus sign of is negative.
c)
As liquid is changing to gas randomness increases and thus sign of is positive.
d)
As 8 moles of gaseous reactants are converted to 11 moles of gaseous products , randomness increases and thus sign of is positive.
Answer:
<h2>
Balloon</h2>
Explanation:
It comes in different colors, it expands when it's "full". It floats away if it is not tied down and will make a loud noise if it pops (breaks).
If you had a specific equation it would help you get a bigger picture.
Basics of balancing equations is making sure you have both sides of the equation, that is reactants and products.
This helps you to know where the oxidation and reduction happened so you can figure out which elements gained or lost electrons and by how much.
Then look and molecules and compounds individually and as a whole, so that you can accurately account for the balance.
Then you have to do alot of practice.
Take up quizes in your free time and the more exposure you have, the better you will familiarize yourself with what to and not to do.
