Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral

Answer:
In the explanation
Explanation:
First of all, make sure you re-read the lesson carefully and memorize the definitions. pls
forces are push and pull.
And just give an example of like someone pushing a sofa into the living room (push).
Another example of pull is pulling a door knob to open a door.
And ANOTHER example can be pushing a tissue box or anything.
Forces can be balanced and unbalanced, that is correct.
When the netforce is equal to 0 then it is balanced, if not then it’s unbalanced.
Balanced which results a netforce equals to 0, there is no change in motion.
Unbalanced which causes in the object's motion changing (For example an tug of war, some guy pulls 10N to the right and the other person 5N to the left, obviously the netforce will be 5N to the right; Unbalanced force)
Last two boxes, maybe add examples as I mentioned? And add another example from ur textbook or something.
