Letter A is the characteristic of all chemical change
If,
10M:250ml
0.05M:Xml
10X=0.05×250
10X=12.5
X=1.25ml
Hope this helps*wink*
The observation that most likely indicates that only a chemical change has taken place is that the change cannot be reversed.
There are two types of change which matter undergoes;
- Physical change
- Chemical change
A chemical change leads to the formation of a new substance so it is usually irreversible.
On the other hand, a physical change is easily reversible. It often involves a change in shape, form or appearance of matter.
If a change is cannot be reversed, it is most likely a chemical change.

Answer:
0.31M is the new concentration of the solution
Explanation:
The solution is diluted from 125mL to 1.0L = 1000mL. The dilution is of:
1000mL / 125mL = 8 times.
That means the concentration of the diluted solution is 8 times lower than the original solution. That is:
2.5M / 8 times =
<h3>0.31M is the new concentration of the solution</h3>
