439.3 g CO2

Explanation:

First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:

3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)

= 9.981 mol CO2

Use the molar mass of CO2 to determine the # of grams of CO2:

9.981 mol CO2 x (44.01 g CO2/1 mol CO2)

= 439.3 g CO2

Describe the number of signals and their splitting in the 1H NMR spectrum of (CH3)2CHOCH3.
yanalaym [24]

Answer:

d. 3 signals: a singlet, a doublet, and a septet

Explanation:

In this case, we can start with the structure of (CH_3)_2CHOCH_3 . When we draw the molecule we will obtain <u>2-methoxypropane</u> (see figure 1).

In 2-methoxypropane we will have three signals. The signal for the CH_3  groups in the left, the CH  and the CH_3  in the right. Lets analyse each one:

-) CH_3  in the right

In this carbon, we dont have any hydrogen as neighbors. Therfore we will have <u>singlet</u> signal in this carbon.

-) CH

In this case, we have 6 hydrogen neighbors ( the two methyl groups in the left). So, if we follow the <u>n + 1 rule</u> (where n is the amount of hydrogen neighbors):

multiplicity~=~n+1~=~6~+~1~=~7

For this carbon we will have a <u>septet</u>.

-) CH_3  in the left

In this case we have only 1 hydrogen neighbor (the hydrogen in CH ). So, if we use the n+1 rule we will have:

multiplicity~=~n+1~=~1~+~1~=~2

We will have a doublet

With all this in mind the answer would be:  

<u>d. 3 signals: a singlet, a doublet, and a septet </u>

A scientist is tracking an object orbiting the sun that is found between mars and Jupiter. Which additional feature can be used
dedylja [7]

Answer:

Size is the additional feature that determines asteroids.

Explanation:

Asteroids are small, rocky objects that orbit the sun. Although asteroids orbit the sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt which is a region between the orbits of Mars and Jupiter.
