Answer:

Mass of neon = 0.3 gram

Explanation:

Given:

Pressure = 842 torr

Temperature = 40.5°C = 313.5 K

Volume = 356 ml = 0.346 l

Find:

Mass of neon

Computation:

Gas constant R = 62.363

Number of mole = (842)(0.346)/(62.636)(313.5)

Number of mole = 0.015 (Approx)

Molar mass of neon is 20 g/ml

So,

Mass of neon = 20 x 0.015

Mass of neon = 0.3 gram

The two naturally occurring isotopes of bromine are

81Br (80.916 amu, 49.31%) and

79Br (78.918 amu, 50.69%).

The two naturally occurring isotopes of chlorine are

37Cl (36.966 amu, 24.23%) and

35Cl (34.969 amu, 75.77%).

Bromine and chlorine combine to form bromine monochloride, BrCl.

Can someone help.? thanks :)​
laila [671]

Answer:

  • <u>1. Equation: 2x  + 3 = 9x - 11</u>

<u></u>

  • <u>2. Each row has 2 chairs</u>

Explanation:

The variable x represents the number of chairs in each row.

<u />

<u>1. She can form 2 rows of a given length with 3 chairs left over.</u>

Thus, she has:

number of rows  number of chairs in      chairs             number of chairs

                             each row                       left over         she has

     2                        x                                    3                      2x + 3

<u>2.  She can form 9 rows of the same length if she gets 11 more chairs.</u>

That means that she is short in 11 chairs to have 9x chairs, or that she has 11 less chairs than 9x chairs. Then she has:

  • 9x - 11

<u>3. Equation:</u>

Then, number of chairs she has is 2x + 3 and, also, 9x - 11, which allows to set the equation:

  • 2x + 3 = 9x  -11

<u>4. Solve the equation:</u>

  • 9x - 2x = 3 + 11
  • 7x = 14
  • x = 2

Therefore, each row has 2 chairs, and she has 2x + 3 = 4 + 3 = 7 chairs.

Methane reacts with chlorine in the presence of ultraviolet light
earnstyle [38]

Answer:

When a mixture of methane and chlorine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is chloromethane. CH 4 + Cl 2 → CH 3 Cl + HCl However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.

According of Dalton's law of Partial pressure, the total pressure of a mixture of gases is the sum of the partial pressures of the individual vases in the mixture.

Hence;

The for hydrogen collected over water, we have a mixture of hydrogen gas and water vapour.

Total pressure = pressure of hydrogen gas + vapour pressure of water

Pressure of hydrogen gas = Total pressure - vapour pressure of water

Pressure of hydrogen gas = 636 mmHg - 28.3 mmHg

Pressure of hydrogen gas = 607.7 mmHg
