#2. There are 60 sec. in a minute and 60 mins. in an hour and 24 hours in a day. The math would be 60•60•60•24=5,184,000. Then, you multiply 5,184,000•7=36,288,000. Multiply 36,288,000•16=580,608,000.

#3. There are approximately 914.4 millimeters in 1 yard. So then, we multiply 914.4•54=49,377.6.

#4. I looked this one up, so I can't show the work for this one but the answer is 0.805 miles per hour.

Rank the compounds in each set in order of increasing acid strength.
Viktor [21]

Answer:

See explanation

Explanation:

For this question, we have to remember the effect of an atom with high <u>electronegativity</u> as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an <u>inductive effect</u>. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be <u>weaker</u> and the compound will be more acid (because is easier to produce the hydronium ion H^+).

With this in mind, for A in the last compound, we have <u>2 Br atoms</u> near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have <u>more acidity</u>. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.

In B, the difference between the molecules is the <u>position</u> of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a <u>higher inductive effect</u> and more <u>acidity</u>.

See figure 1

I hope it helps!
