Hello there! Your answer is A. 640 J
You can get this by subtracting the temperatures (-136-120= -256.) Then, you divide this answer by 40.0 g to get 6.4.
Salts that are from strong bases and strong acids do not hydrolyze. Salts that are from strong bases and weak acids do hydrolyze, which gives it a pH greater than 7. Salts of weak bases and strong acids do hydrolyze, which gives it a pH less than 7.
Explanation:
Using the periodic table, to predict the chloride that is ionic or not, we should first understand how ionic compounds are formed.
Ionic compounds are formed between a highly electronegative element and less electronegative one.
- It is usually a bond formed between metals and non-metals.
- Metals are on the left block and non-metals on the right block.
- In the formation of this bond type, a metal loses its excess electrons and becomes positively charged.
- A non-metal gains the electron and becomes negatively charged.
- The electrostatic force of attraction between the two species causes the formation of ionic bonds.
- Ionic bonds forms between metals and non-metals with appreciable electronegative differences.

Explanation:
This indicate that there is a type of pressure or anticyclone that is affecting the area. This means Air would sink down slowly, instead of it rising and cooling.
It happen that Sometimes the clouds heat up and the liquid water will change into vapor. The water droplets present in the clouds will not be as heavy as the surrounding air
Answer:
B
Explanation:
The student is not able to move the box in D --> 55N, 0N. Since the net force is 0, it means that no force is being applied. So you will choose answer B from your options.
Hope this helps, thank you !!
