Which corresponds to pressure of 1.23 atm? 8.73 mmhg 9.23 mmhg 125 mmhg 935mmhg

- 935 mmHg.

Solution:- It is a unit conversion problem where the given pressure is 1.23 atm and we need to convert it to mmHg and see which choice is the right one.

The conversion factor from atm to mmHg is:

1 atm = 760 mmHg

Let's make the set up using this conversion factor to convert 1.23 atm to mmHg:

= 935 mmHg

So, the last choice is correct. The pressure is 935 mmHg.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
