Find gas pressure of 2.5 moles H2 and 4.6 moles Ne at 1400mmHg.

Chemistry

Monica [59]2 years ago
5 0

Answer:

Pressure of neon = 1.17 atm

Pressure of hydrogen = 0.63 atm

Explanation:

Given data:

Number of moles of H₂ = 2.5 mol

Number of moles of Ne = 4.6 mol

Total pressure = 1400 mmHg (1400/760 = 1.8 atm)

Solution:

We will solve this problem through mole fraction method.

Total number of moles = 2.5 + 4.6 = 7.1

Mole fraction of H₂                                         Mole fraction of Ne

2.5 mol/7.1 mol= 0.35                                     4.6mol/7.1mol = 0.65

Pressure of hydrogen = 0.35 × 1.8 atm

Pressure of hydrogen = 0.63 atm

Pressure of neon = 0.65 × 1.8 atm

Pressure of neon = 1.17 atm

Total pressure which is already given is sum of partial pressure of hydrogen and neon gas.

0.63 atm + 1.17 atm = 1.8 atm

3Ag^(+) + 3Cl ^(-) --> 3AgCl (s)

Explanation:

Full ionic equation:

3Ag^(+) + 3NO3^(-) + Al^(+3) + 3Cl^(-)-->

3AgCl (s) + Al^(3+) + 3NO3^(-)

Spectator ions 3NO3^(-) & Al^(+3) can be left out in the net ionic equation.

A balloon contains 3.20 L of helium. The pressure is reduced to 59.0 kPa, and the
pshichka [43]

Answer:

101.4pKa

Explanation:

Given parameters:

Initial Volume of helium  = 3.20L

Final pressure of helium  = 59kPa

Final volume on helium gas = 5.5L

Unknown:

Initial pressure exerted on the balloon = ?

Solution;

To solve this pressure - volume problem, we simply apply the Boyle's law.

It states that "the volume of a fixed mass gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

         P1 V1  = P2 V2

Now, insert parameters and solve;

         P1 x 3.2 = 59 x 5.5

          P1  = 101.4pKa

Which of the following correctly describes the relationship between speed and velocity?
rodikova [14]
Speed and velocity is a scalar and vector quantity of a similar parameter, respectively. They both refer to how fast an object moves. However, the speed only has to do with the magnitude. The velocity takes into account the sign which indicates the direction of the movement. For example, the value is -5 m/s. The speed is 5 m/s, but the velocity is 5 m/s moving downwards because the negative sign denotes downward movement or movement to the left.
