The following structure depicts three C atoms, two Br atoms, and eight H atoms,
Darya [45]

Answer: False

Explanation: There are four carbon atoms , eight hydrogen atoms and two Bromine atoms.

As the carbon forms four covalent bonds, every carbon must have four bonds and thus the formula of the compound is BrCH_2-CH(Br)-CH_2-CH_3.

IUPAC name of the compound is 1,2 di-bromobutane. As the carbon chain is 4 atoms long the word used is but and all the bonds are single bonds, thus the suffix used is ane.

Consider the reaction: 2 SO2(g) + O2(g) <----> 2 SO3. If, at equilibrium at a certain temperature, [SO2] = 1.50 M, [O2] =
vlada-n [284]

Answer:

5.79

Explanation:

The following data were obtained from the question:

Concentration of SO2, [SO2] = 1.50 M

Concentration of O2, [O2] = 0.120 M

Concentration of SO3, [SO3] = 1.25 M

Equilibrium constant, (K) =..?

The balanced equation for the reaction is given below:

2SO2(g) + O2(g) <==> 2SO3(g)

From the balanced equation, the equilibrium constant K is written as follow:

K = [SO3]²/ [SO2]²• [O2]

With the above, the value of the equilibrium constant, K can be obtained as follow

K = [SO3]²/ [SO2]²• [O2]

K = (1.25)² / (1.50)² × 0.120

K = 1.5625 / ( 2.25 x 0.120)

K = 5.79

Therefore, the equilibrium constant is 5.79.

How much energy does an X-ray with an 8 nm (8 x 10-9m) wavelength have?
myrzilka [38]

Answer:

it would be option C

Explanation:

Speed of light = 3×10^8m/s

Planck's constant = 6.626×10^-34 Js

Wavelength = 8 x 10^-9 m

Energy = [(3×10^8) * (6.626×10^-34)] / 8 x 10^-9

Energy = [19.878×10^(8-34)] / 8 x 10^-9

Energy = 2.48475 × 10^(-26+9)

Energy = 2.48×10^-17 J
