A student titrates 60.0 mL of a nitric acid solution to the equivalence point with 42.0 mL of a 0.30 M sodium hydroxide solution. Phenolphthalein is used as an indicator. When the equivalence point is reach the indicator color change remains and the student stops titrating. After titrating to the equivalence point, what is the concentration of the nitric acid solution?

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
