Colt1911 [192]3 years ago
8 0

Answer:

C₇ H₁₆   +   11O₂    →   7CO₂     +    8H₂O

Explanation:

Given equation

       C₇ H₁₆   +   O₂   →   CO₂    +    H₂O

To solve this problem,

 We use a mathematical approach to balance the equation:

             aC₇ H₁₆   +   bO₂    →   cCO₂     +    dH₂O

Conserving C; 7a = c

                   H ; 16a  = 2d

                   O: 2b  = 2c + d

Let a  = 1

     c  = 7

    d  = 8

    b  = 11

Now insert the parameters and solve;

   

      C₇ H₁₆   +   11O₂    →   7CO₂     +    8H₂O

A balloon is filled with 0.250 mole of air at 35°C. If the volume of the balloon is 6.23 liters, what is the absolute pressure
lord [1]

Answer is:  the absolute pressure of the air in the balloon is 1.015 atm (102.84 kPa).

n = 0.250 mol; amount of substance.

V = 6.23 L; volume of the balloon.

T = 35°C = 308.15 K; temperature.

R = 0.08206 L·atm/mol·K, universal gas constant.

Ideal gas law: p·V = n·R·T.

p = n·R·T / V.

p = 0.250 mol · 0.08206 L·atm/mol·K · 308.15 K / 6.23 L.

p = 1.015 atm; presure of the air.

1. Show the mechanism for the main product for the monochlorination of 2-methylbutane. List all other products.
Bad White [126]

Answer:

See explanation below

Explanation:

First, we need to understand that the monochlorination of an alkane like this one, involves substitution of one of the atoms of hydrogen of the molecule for an atom of chlorine.

This reaction takes place when the alkane reacts with Cl₂ in presence of light or heat.

When this happens, the first step involves the breaking of the double bond of the chlorine to form the ion Cl⁻.

The next step involves the substraction of the hydrogen of the molecule by the Chlorine. This will leave the alkane with a lone pair available for reaction.

The third step, the alkane with the lone pair of electron substract a chlorine for the beggining and form the mono chlorinated product.

The final step involves forming the remaining products with the remaining reagents there.

In the picture attached you have the mechanism and product for this reaction:
