A chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water. What is the concentration of the final solution?
Use M subscript i V subscript i equals M subscript f V subscript f..
0.300 M
0.375 M
6.00 M
7.50 M

Explanation:

This question tests for concentration after dilution of the solution. is added to 200ml of water.

The formula for concentration correlation is given as , where the latter relates to the final solution mix.

Therefore the concentration is 0.300M

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
