Explanation:

<h3><em><u>Genotypes</u></em><em><u>:</u></em><em><u>-</u></em></h3>

<em><u>Hh, Hh, hh and hh </u></em>

<h3><em><u>Phenotypes</u></em><em><u>:</u></em><em><u>-</u></em></h3>

Hh = Hh = May be long hair or short hair

hh = hh = Short hair

<em><u>So</u></em><em><u>,</u></em>

<em><u>Mainly</u></em><em><u> </u></em><em><u>phenotypes</u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>Long</u></em><em><u> </u></em><em><u>hair</u></em><em><u>,</u></em><em><u> </u></em><em><u>long</u></em><em><u> </u></em><em><u>hair</u></em><em><u>, </u></em><em><u>short</u></em><em><u> </u></em><em><u>hair</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>short</u></em><em><u> </u></em><em><u>hair</u></em><em><u>.</u></em>

A bottle of wine contains 9.81 grams of C2H5OH, dissolved in 87.5 grams of water. The final volume of the solution is 100.0 mL.
dimulka [17.4K]

Answer:

[EtOH] = 2.2M and Wt% EtOH = 10.1% (w/w)

Explanation:

1. Molarity = moles solute / Volume solution in Liters

=> moles solute = mass solute / formula weight of solute = 9.8g/46g·mol⁻¹ = 0.213mol EtOH

=> volume of solution (assuming density of final solution is 1.0g/ml) ...

volume solution =  9.81gEtOH + 87.5gH₂O = 97.31g solution x 1g/ml = 97.31ml = 0.09731 Liter solution

Concentration (Molarity) = moles/Liters = 0.213mol/0.09731L = 2.2M in EtOH

2. Weight Percent EtOH in solution (assuming density of final solution is 1.0g/ml)

From part 1 => [EtOH] = 2.2M in EtOH = 2.2moles EtOH/1.0L soln

= {(2.2mol)(46g/mol)]/1000g soln] x 100% = 10.1% (w/w) in EtOH.

Predict the sign of ΔSsys for each of the following processes. Which are positive? (a) Gasoline vapors mix with air in a car eng
OLEGan [10]

Answer:

Positive: a and b

Negative: c

Explanation:

The entropy (S) is the measure of the randomness of the system, and it intends to increase. The randomness can be determined by the energy of the molecules, their velocity and how distance they are between the other molecules.

When the entropy increases, ΔS is positive, when the entropy decreases, ΔS is negative. So, when gasoline mix with air in a car engine, the process intends to continue, the randomness increases and ΔS is positive. When hot air expands, the distance between the molecules increases, so ΔS is positive.

But, when humidity condenses, the molecules stay closer, so there's a decrease in the randomness, then ΔS is negative.

When an aqueous solution containing hydrochloric acid is just neutralized with an aqueous solution containing sodium hydroxide,
Elza [17]

Answer:

c. salty.

Explanation:

From the question,

The reaction of an acid , i.e hydrochloric acid and a base i.e. , sodium hydroxide takes place , which is a type of neutralization reaction,

Where the acid and a base reacts to give salt along with water .

From the question,

The reaction is as follows -

2 HCl  +  NaOH  →  NaCl  +  H₂O  

Hence, the resulting product is a salt ,

Therefore , the resulting solution would taste like salt.
