Answer: The only possibly answer that makes the most logical sense is a
Explanation: B. wouldn't make it any better only worse making the population die out it would help more in a cold C. doesn't make sense either their ground squirrels but they can still climb and finally D. there in Africa everything is basically beige and they would stick out more making them easy prey.
A makes it easier to blend in with their surroundings and giving them a higher survival chance
Answer:
The third option is what a tsunami is.
Explanation:
To make computations easier, let us assume that there is 1 liter solution of the sample.
So using the density formula to know what the mass of this sample would be:
1 L x 1000 mL / 1L x 1.20g/ 1 mL = 1120g
Now use the percent concentration by mass to know how many grams of HCl you can have:
1120 g sol x 39 g HCl / 100 g = 313.6 g HCL
To determine the solution's molarity, use the molar mass to know the number of moles present:
313.6g x 1 mole / 36.46g = 8.60 moles
since the sample has a volume of 1 L, the molarity is:
C = n / V = 8.60 moles / 1.0 L = 8.60 M
To get the solution's molarity, determine the mass of water.
Msol = Mwater + Macid
Mwater = Msol - Macid = 1120 - 313.6 = 806.4 g
The molarity will be:
b = n/ Mwater = 8.60 moles / 806.4 x 10^-3 = 10.66 molal
the solution's molarity will be equal to its normality since HCl acid can only release one mole of protons per mole of acid
Normality = 8.6 N
