Equationa and expansion do not refer to the same things.
An equation is something like: x + 1 = 5
The equation can then be solved to find the value of x (in this case it is 4).
An expansion usually refers to expanding out brackets or something similar.
For example:
2(x+1) = 2x + 2
or
(x+1)2 = x2 + 2x + 1
Binomial Expansion makes it easier to solve an equation. It brings an equation of something raised to a power down to a solveable equation without parentheses.
No, but both describe the same chemical reaction.
An equation that gives the coefficient of thermal expansion of whatever the material is.
An equation is equivalent to another equation, if they have the same solution.
yes
An equality and equation are essentially the same thing. The equality between two expressions is represented by an equation (and conversely).
"430 5" is not an equation and it does not have an unknown value. So there can be no equation which has the same unknown value.

No.
In an equation, the left side has the same value as the right side. The importance of doing the same thing to both sides is to keep the value of both sides the same so the equation does not change.
