Hello!
The general chemical equation for the neutralization of an acid HA with NaOH is the following:
HA(aq) + NaOH(aq) → NaA(aq) + H₂O(l)
For determining the concentration of the acid solution, we can use the equation shown below:

So, the concentration of the Acid is
0,36 MHave a nice day!
To find the area of something you have to multiply the length x the with x the height. Or if it gives to the base then you multiply the base x the height.
What differ the noble gases from all the other elements is that the noble gases have a full valence electron energy level which consists in 8 valence electrons
C. A tree Trees can turn light into chemical energy using photosynthesis.
As you said, the answer is 150.
But in all the numbers, there's a comma with two zeros, and so you have to put them in your answer : 150,00
They are the significative numbers.
Hope it helps
