1. The reaction is exothermic.

2. I know this because the delta H is a negative number. (-802.4 kJ)

3. This means that this reaction releases heat.

I will, but do you find that we have our own priorities in life? Do you find that life is worth finding a real job? Life is worth finding a real pastime? Life is worth fiding a real place to belogn?
We do not belong on this world. But we belong in our hearts, our minds towards thecenter. We should not hesitate.

Butene, used as the monomer for polybutene, is composed of 85.7% and 14.3% by mass. If the density of butene is 2.50 g/L at STP,
Ann [662]

Answer:

C₄H₈

Explanation:

In the first, you should know the ideal gas law. One of the formula for this concept is:

MW = (δ*R*T) / P where:

MW is molecular weight, δ is density 2,50 g/L, R is the gas constant (0,082 (atm*L) / (mol*K) ), T is temperature (273,15 K at STP) and P is pressure (1 atm).

So:

MW = [2,50 g/L * 0,082 (atm*L) / (mol*K) * 273,15 K ] / 1 atm

MW = 56 g/mol

Then the problem says than butene is composed by 85,7% (of carbon) and 14,3 % (of hydrogen). So:

Carbon mass: 56 g/mol * 85,7% = 48 g/mol / 12 g/mol ( atomic mass of carbon = 4 carbon atoms.

And, hydrogen mass: 56 g/mol * 14,3% = 8 g/mol / 1 g/mol ( atomic mass of hydrogen = 8 hydrogen atoms.

Thus, the molecular mass of butene is: C₄H₈

I hope it helps!
