A24% acid solution is mixed with a 14% acid solution to form a 19% acid solution. how many liters of the 24% acid solution are used to make 10 liters of the 19% acid solution?

5 Liters

Explanation:

According to the dilution law,

where,

= concentration of first solution = 24%

= volume of first solution = x L

= concentration of second solution = 14%

= volume of second solution = (10-x) L

= concentration of final solution = 19%

= volume of final solution = 10 L

Putting i the values, we get:

Therefore, 5 Liters of the 24% acid solution are used to make 10 liters of the 19% acid solution.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
