Based on its geometric structure, which molecule is nonpolar?

1 answer:

8 0

I think the correct answer from the choices listed above is the third option. Carbon tetrachloride is a nonpolar molecule. <span> because the bond polarity is canceled by the symmetric tetrahedral shape. Hope this answers the question. Have a nice day.</span>

Please answer, please answer please answer please answer<br>my last 2 chemistry question.

scoundrel [369]

Answer:

1. filtration and evaporation

2. i) water is added to the sand and salt mixture

ii) then the mixture is filtrated and so the sand and the salt water was seperated

iii) the salt water is heated with the help of burner until the water gets evaporated

iv) after the water gets evaporated, the salt is remained in the container

3. observation:

on adding water to the mixture, the salt is completely dissolved in the water
when filtrated the sand is seperated from the salt water
now the salt water when heated with the burner until the evaporation, the water is evaporated
the salt is precipitated and remained in the container

4. cautions:

while using the burner, we should be cautious with fire
the container that is heated should be holded with the help of a cloth to avoid heat

PLEASE HELP!!!!!!

Answer:

$m_{B}^{theoretical}=0.365gB$

$Y=87.1\%$

Explanation:

Hello there!

In this case, since the reaction (A->B) have an initial amount of pure 4-aminobenzoic acid, the first step to compute the theoretical yield is to solve the following stoichiometric setup:

$m_{B}^{theoretical}=0.303gA*\frac{1molA}{137.14gA}*\frac{1molB}{1molA}*\frac{165.19 gB}{1molB}\\\\ m_{B}^{theoretical}=0.365gB$

Whereas A stands for 4-aminobenzoic acid and B for the benzocaine. Moreover, we compute the percent yield by dividing the actual yield (0.318 g) by the theoretical one (0.365 g):

$Y=\frac{0.318g}{0.365g} *100\%\\\\Y=87.1\%$

Best regards!
