Using the above information answer the following questions: 1. From the data and known information calculate the moles of hydrobromic acid that were titrated in each
experiment.
2. Write the balanced chemical equation for the reaction.
3. Based on the equation in #2, how many moles of base are required to neutralize the acid?
4. Using the moles of base determined in question #3 calculate the molarity of the base.
5. How many grams of potassium hydroxide were used.

gas

explanation:

smoke is the matter of a gas

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 objects have the same charge is correct.
