Question 13 (1 point)
Match the pH level to the correct term.
Column A
1._pH 0-3
2._ ph 4-6
3.__ph 8-10
4.__ ph 11-14
5.__ph 7

Column B
a. Strong base
b. Weak acid
C. Strong acid
d. Neutral
e. Weak base

1=C

2=B

3=E

4=A

5=D

Explanation:

Closer to 0 is more acidic, closer to 14 is more basic. 7 is neutral and the cut off point between if acidic or basic.

c. 75.7

i think that is the right

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
