I would say C but I am just in 7th grade soo
If It takes 60mL of 0.20M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (), then the concentration of the carbonic acid is 0.24M
The reaction between NaOH solution and is written below
Volume of NaOH, = 60 ml
Volume of ,
Molarity of ,
Molarity of NaOH,
Number of moles of ,
Number of moles of NaOH,
The mathematical equation for neutralization reaction is:
Substitute , , , = 60ml, and into the equation above in order to solve for
Therefore, the concentration of the carbonic acid is 0.24M

Answer:
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
I hope it helps
The solubility constant or Ksp is calculated by the product of the concentration of the ions raise to the stoichiometric coefficient. We calculate as follows:
BaCrO4 = Ba2+ + CrO42-
Ksp = [Ba2+][CrO4]
Ksp = [1.08×10−5<span> ] [1.08×10−5] = 1.1664x10^-10</span>
