How many valence electrons are in cbr2cohnh2

Chemistry
1 answer:
marishachu [46]3 years ago
8 0

Answer:

36 valence electrons

Explanation:

Given CBr₂COHNH₂ => Br₂C = C - O - H

                                                    |

                                             H - N - H

#Valence e⁻s  = 2Br + 2C + 3H + 1N + 1O = 2(7) + 2(4) + 3(1) + 1(5) + 1(6)

    = 14 + 8 + 3 + 5 + 6 = 36 valence electrons

Addendum ...

#Bonded e⁻s =  2Br + 2C + 3H + 1N + 1O = 2(8) + 2(8) + 3(2) + 1(8) + 1(8)

   = 16 + 16 + 6 + 8 + 8 = 54 bonded electrons

#Covalent Bonds = #Valence e⁻ - #Bonded e⁻ / 2 = (54 - 36) / 2 = 9 cov. bonds.

What amount of acid is esterified if a mixture consist initially of 1.0mole of ethanoic acid,1.0mole of ethanol and 1.0mole of w
ale4655 [162]

Answer:

0.54 mole

Explanation:

                                     CH3COOH    CH3CH2OH   CH3COOCH2CH3    H2O​

Initial concentration   1.0 mole         1.0 mole                0 mole                  1.0mol

Change                          - x                   - x                      + x                          + x  

Equilibrium                   (1.0 - x)          (1.0 - x)                   x                       (1.0 + x)

K = [CH3COOCH2CH3]*[H2O​]/[CH3COOH]*[CH3CH2OH]

x*(1.0+x)/(1.0-x)(1.0-x) = 4.0

x+x²=4*(1-x)²

x+x² = 4(1² - 2x + x²)

x + x² = 4 - 8x + 4x²

4 - 8x + 4x²- x² - x= 0

3x² - 9x + 4 = 0

x=2.5 , x=0.54

2.5 mole of acid cannot be esterified, because there is only 1.0 mole of acid,

so answer is 0.54 mole.

A firefighter applies a force of 2 N to lift the fire hose 3 meters up a ladder to put out a fire. How much work has the firefig
Paraphin [41]

Answer:

6 J

Explanation: Work done(J) = Force(N) × Distance(m) along the direction of force.

Given, Force=2 N, Distance=3 meters

∴ Wok done (J) = 2 × 3 = 6 J.
