Answer from: tiffg2588

The total volume of the solution at the end point of the titration is 17.0 mL

Explanation:

First we will write a balanced chemical equation for the reaction between HCl and NaOH.

HCl + NaOH → NaCl + H₂O

This means 1 mole of HCl will react with 1 mole of NaOH to give 1 mole of NaCl and 1 mole of H₂O

From the question,

Concentration of acid (HCl), $C_{A}$ = ??

Volume of acid (HCl), $V_{A}$ = 5.0 mL

Concentration pf base (NaOH), $C_{B}$ = 0.010 M

Volume of base (NaOH), $V_{B}$ = 12.0 mL

To determine the Concentration of acid, $C_{A}$

From,

$\frac{C_{A}V_{A} }{C_{B}V_{B} } = \frac{n_{A} }{n_{B} }$

Where $n_{A}$ is the mole ratio of acid

and $n_{B}$ is the mole ratio of base.

The concentration of the acid used can be determined from the above formula.

But, we are asked to find the total volume of the solution at the end point of the titration

The total volume of the solution will be the sum of the volume of HCl that reacted and volume of NaOH that reacted.

Hence, The total volume of the solution = $V_{A} + V_{B}$

= 5.0 mL + 12.0 mL

= 17.0 mL

Hence, the total volume of the solution at the end point of the titration is 17.0 mL

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic

Answer from: Quest

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
