Answer:

121.8bar

Explanation:

The partial pressure is the pressure a gas would exert if it were alone in the volume of the gas mixture;

 Given parameters:

  Total pressure  = 2558psi

   Partial pressure of carbon dioxide  = 54.6bar

Unknown:

Partial pressure of nitrogen dioxide gas  = ?

Solution:

  Total pressure = partial pressure of carbon dioxide + partial pressure of nitrogen dioxide gas

Let us convert from psi to bar;

           14.504psi  = 1 bar

           2558psi  = \frac{2558}{14.504}   = 176.37bar

Now;

Partial pressure of nitrogen oxide = 176.37bar  - 54.6bar  = 121.8bar

Answer:

1766 psi

Explanation:

The first step is to convert 54.6 bar into psi units, which is aproximately 791.9 psi. Next, subtract that from 2558 psi and you will get about 1766 psi.

5. Health hazards- Video games may lead to health hazards- such as nerve compression, obesity, and video-induced seizures.

The positive effect of video games are:

1. Problem solving - Video games train ones brain to be creative and also come up with solution to challenges.

2. Quick thinking - Video games help one to think quickly in order to solve challenges and overcome obstacles.

3. Create positive emotions - Easy games can bring about positive emotions and uplift ones mood, and help in promoting relaxation.

Which out of two has stronger forces of attraction sugar or water very sort answer​
Marina CMI [18]

Sugar. It is solid and its atoms have less kinetic energy to overcome the bonding force. So, the bonding force is stronger than water, which is liquid and has more kinetic energy to overcome the bonding force of atoms. So, water has less strong force of attraction. Hence, sugar has stronger forces of attraction.

A sample of oxygen gas has a volume of 3.24 L at 29°C. What volume will it occupy at 104°C if the pressure and number of mol are
ohaa [14]

<u>Answer:</u> The final volume of the oxygen gas is 4.04 L

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=3.24L\\T_1=29^oC=(29+273)K=302K\\V_2=?\\T_2=104^oC=(104+273)K=377K

Putting values in above equation, we get:

\frac{3.24L}{302K}=\frac{V_2}{377K}\\\\V_2=4.04L

Hence, the final volume of the oxygen gas is 4.04 L
