Explanation:
Answer:
Mammals do not have instincts, so they must learn all their behaviors from their parents in order to survive.
Sea turtles must survive on their own, while mammals spend time with their parents and learn how to survive as they grow.
Sea turtles are less intelligent than mammals and, thus, cannot learn new behaviors from their parents.
Explanation:
Answer:
HCl(aq) + KOH(aq) ===> H2O(l) + KCl(aq)
Note the stoichiometry of the balanced equations shows us that HCl and KOH react in a 1:1 mole ratio. So, let us find moles of HCl and moles of KOH that are present:
moles HCl = 250.0 ml x 1 L/1000 ml x 0.25 mol/L = 0.06250 moles HCl
moles KOH = 200.0 ml x 1 L/1000 ml x 0.40 mol/L = 0.0800 moles KOH
You can see that there are more moles of KOH than there are of HCl, meaning that KOH is in excess and after neutralizing all of the HCl, the solution will be left with excess KOH making the pH > 7 = BASIC
The answer is chemical weathering
