Answer:

D. chlorine, oxygen, nitrogen, hydrogen.

Explanation:

  • Thomas Graham found that, at a constant  temperature and pressure the rates of effusion  of various gases are inversely proportional to  the square root of their masses.

<em>ν ∝ 1/√M</em>

where ν is the rate of effusion and M is the atomic  or molecular mass of the gas particles.

  • The molecular mass for the listed gases are:

O₂: 32.0 g/mol,

Cl₂: 70.906 g/mol,

N₂: 28.0 g/mol,

H₂: 2.0 g/mol.

  • Hence, the smallest molecular mass of the gas, the fastest rate of effusion.

So, the order from the slowest to the fastest rate of effusion is:

<em>Chlorine, oxygen, nitrogen, hydrogen.</em>

If the molecules in the above illustration react to form NH3 according to the equation N2 3 H2 2 NH3 , the limiting reagent is ,
Kamila [148]

Answer:

Follows are the solution to these question:

Explanation:

Given equation:

N_2+3H_2 \longrightarrow 2NH_3

In this equation:

1 N_2 gives = 2NH_3

so,

3N_2 gives=  2 \times 3 = 6 NH_3

similarly:

3H_2 gives = 2NH_3

So, 6H_2 gives = \frac{2}{3}\times 6=4NH_3

Its limited reagent is =N_2

The amount of NH_3 molecules were formed = 4.

and the amount of  H_2 excess molecules are= 1

A sample of gas has a volume of 12.0L and a pressure of 2.00 atm. If the pressure of gas is increased to 6.00 atm, what is the n
prisoha [69]

Answer:

B; 4 L

Explanation:

From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas

Mathematically, we have this as;

PV = K

Given;

P1 = 2 atm

V1 = 12 l

P2 = 6 atm

V2 = ?

We have that;

P1V1 = P2V2

2 * 12 = 6 * V2

V2 = (2 * 12)/6

V2 = 24/6

V2 = 4 L
