Answer:
D) both groups are equatorial.
Explanation:
To solve this question we can start by drawing the molecule in using the <u>structure of the hexagon</u>. In this structure, we have the methyl group on carbon 1 and the terbutyl group on carbon 3, additionally, if we have a cis structure both groups must have the same type of bond (in this case the wedge bond). (See figure 1)
When we write the <u>chair structure</u>, we must keep the same structure. That is, methyl must be on carbon 1 and terbutyl on carbon 3. Also, the cis configuration must be maintained. With this in mind, we can choose the <u>equatorial configuration</u> for methyl on carbon 1 (since the position equatorial is the one that has <u>less steric impediment and more stability</u>). If this is true for carbon 1, we must place the terbutyl group on carbon 3 in the same configuration (i.e. cis). Therefore, on carbon 3 we must place the tert-butyl down on carbon 3, that is, in the <u>equatorial position</u>. (See figure 1).
Therefore, in the chair-like structure, both groups must be in an equatorial position.

Explanation:
Because molarity is classified as moles of solute per liter of water, dilution of the water may result in a reduction of its concentration.
Therefore, because the amount of moles of solute has to be constant for dilution, you will use the molarity and volume of that same target solution to calculate how many moles of solute will be present in the sample of the stock solution that you dilute.
c =
⇒ n
=
c
⋅ V
= 0.250 M ⋅ 6.00 L =
1.5 moles HCl
Now all you have to do is figure out what volume of 6.0 M stock solution will contain 1.5 moles of hydrochloric acid
c =
V =
= =
0.25 L
Expressed in milliliters, the answer will be
→ rounded to two sig figs
The solubility product is calculated using the ions that are formed by the dissolution of a solid. Therefore, the reaction for this solubility product expression is:
Ag₂CO₃ → 2Ag⁺ + CO₃⁻²

Answer:
Percent Yield = 80%
Explanation:
Percent yield of a reaction is defined as one hundred times the ratio between the actual yield and the theoretical yield. That is:
Percent yield = Actual Yield / Theoretical Yield * 100
<em>Where theoretical yield of CaHPO4 is 10g and actual yield is 8g</em>
Replacing:
Percent yield = 8g / 10g * 100
<h3>Percent Yield = 80%</h3>
