Usimov [2.4K]

Answer: C. Harmful, because it will have a harder time sneaking up on its prey

Explanation: White skin on an alligator would be detrimental because it would not be able to blend in to its surroundings as well, as the white skin would stand out from the greens and browns of the swamps in which alligators normally inhabit. Most alligators also live in warmer climates, so there would not be much opportunity to try and blend into any sort of snow.

A 0.397-g sample of potassium hydrogen phthalate, KHC8H4O4 (molar mass = 204.22 g/mol) is dissolved with 50 mL of deionized wate

stiks02 [169]

Answer: The molarity of NaOH solution is 0.1196 M

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass of KHP = 0.397 g

Molar mass of KHP = 204.22 g/mol

Putting values in above equation, we get:

$\text{Moles of KHP}=\frac{0.397g}{204.22g/mol}=0.00194mol$

The chemical reaction for the reaction of KHP and NaOH follows

$KHC_8H_4O_4(aq.)+NaOH\rightarrow KNaC_8H_4O_4(aq.)+H_2O(l)$

By Stoichiometry of the reaction:

1 mole of KHP reacts with 1 mole of NaOH.

So, 0.00194 moles of KHP will react with = $\frac{1}{1}\times 0.00194=0.00194mol$ of NaOH.

To calculate the molarity of NaOH, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

We are given:

Moles of NaOH = 0.00194 moles

Volume of solution = 16.22 mL = 0.01622 L (Conversion factor: 1 L = 1000 mL)

Putting values in above equation, we get:

$\text{Molarity of NaOH }=\frac{0.00194mol}{0.01622L}=0.1196M$

Hence, the molarity of NaOH solution is 0.1196 M
