Answer:
The answer to your question is 0.92 atm
Explanation:
Data
Atmospheric pressure = 27.6 inHg
Atmospheric pressure = ? atm
Process
1.- Convert inHg to cmHg
1 in Hg ------------------- 2.54 cm
27.6 inHg ----------------- x
x = (27.6x 2.54) / 1
x = 70.1 cm
2.- Convert cmHg to mmHg
2.54 cm ----------------- 25.4 mmHg
70.1 cm ---------------- x
x = (70.1 x 25.4)/2.54
x = 701 mmHg
3.- Convert mmHg to atm
760 mmHg ------------- 1 atm
701 mmHg ------------- x
x = (701 x 1)/760
x = 0.922 atm
Answer:
Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.
Explanation:
- <em>Strong electrolytes</em> completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are:<u> salt water</u>, <u>baking soda (NaHCO3) solution.</u>
- <em>Weak electrolytes</em> do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be<u> vinegar </u>and <u>bleach </u>(which could be sodium hypochlorite or chlorine, which are weakly dissociated).
- <em>Non-electrolytes </em>will remain as molecules and are not ionized in water at all. In this case, <u>sugar solution is a non-electrolytes</u>, even though sugar dissolves in water, but it remains as a whole molecule and not ions.
First you need to count the atoms of each element in the reactantsa and the products. Then use coefficients and place them in front of the compunds until the equations looks fully balanced.
