33 POINTS PLEASE HELP. A mixture of hydrogen and oxygen gases has a total pressure of 5.50 atm. What is the partial pressure of the hydrogen if the P (O2) = 1250 mm Hg?

2930 mmHg

Explanation:

We need to convert these two different units of pressure into the same. Let's just use mmHg. So, we need to go from atm to mmHg. The conversion factor is 1 atm = 760 mmHg. We have 5.50 atm, so multiply 760 by 5.50: 4180 mmHg.

Now, partial pressure means that the pressures of each of the different gases will add up to the total pressure. Here, our total pressure is 4180 mmHg and the pressure of oxygen is 1250 mmHg. So to find the pressure of hydrogen, we simply subtract 1250 from 4180: 4180 - 1250 = 2930 mmHg.

Hope this helps!

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
