What volume of a 3.0 m stock solution of h2so4 is needed to prepare 2.8 l of a 1.6 m h2so4 solution?

The volume of stock solution needed is 1.5 L

Explanation:

To calculate the molarity of the diluted solution, we use the equation:

where,

are the molarity and volume of the stock solution

are the molarity and volume of diluted solution

We are given:

Putting values in above equation, we get:

Hence, the volume of stock solution needed is 1.5 L

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

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
