Could someone explain Endothermic vs. Exothermic reactions to me please?
What are reversible reactions?
What's a dynamic equilibrium?
And how do you read the pH scale?

Endothermic = absorbs heat energy from surroundings (gets cold)
Exothermic = releases heat to surroundings (gets hot)
reversible reactions are just that- reversible
dynamic equilibrium = the reaction and the reverse of it are happening at the same rate
pH = the negative log of the hydronium ion concentration.
ph of 2 indicates 10^-2 ions per (whatever) (which is acidic), which is MORE than ph of 9, which indicates 10^-9 ions (basic)

Endothermic absorb and exothermic release heat.
Reversible reactions return to their original state if deviated very little.
When rates of forward and backward reactions are equal.
<7 Acidic
7 Neutral
>7 Alkaline.
