Answer:

See figure 1

Explanation:

In this question, we have to find first the <u>chiral carbons</u> on 1,2-difluoro-1,2-dimethylcyclopentane. Carbons 1 and 2. Then, using the <u>Cahn–Ingold–Prelog priority rules</u>. We can draw all the stereoisomers. If we have 2 chiral carbons we will have (2^n=2^2=4) <u>4 isomers</u>. With this in mind we can have the R,R isomer; the S,S isomer; the S,R isomer, and the R,S isomer. We have to remember that:

<u>Priority 1 = "F"</u>

<u>Priority 2= "C"</u>

<u>Priority 3= "CH2"</u>

<u>Priority 4 = "CH3"</u>

I hope it helps!

Which term refers to an electrochemical cell that produces an electric current?
ArbitrLikvidat [17]
Correct answer: Galvanic cell

Reason:
Following are the differences between Galvanic cell and electrolytic cell:
1. <span>Galvanic cell converts chemical energy into electrical energy , on other hand <span>electrolytic cell converts electrical energy into chemical energy.
2. In galvanic cell, </span></span><span>redox reaction is spontaneous and is responsible for the production of electrical energy. in electrolytic cell, t<span>he redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.

Thus, galvanic cell </span></span><span>refers to an electrochemical cell that produces an electric current</span>

What will happen to the chemical equilibrium if NH4Cl is added to this solution?
Tresset [83]
The answer to this item depends entirely to the chemical reaction. If the compound, NH4Cl, is in the left hand side of the reaction, when it is added, the reaction will shift to the left. In the same manner, when the compound is in the right-hand side of the reaction, the reaction will shift to the right.

This happens because initially the reaction is in equilibrium and adding another compound to it will most likely lead to the shifting of the reaction.

Nitrogen has two isotopes. One has an atomic mass of 14.003 amu and a relative abundance of 99.63% while the other isotope has a
Slav-nsk [51]

Answer:

Average atomic mass = 14.0067  amu.

Explanation:

Given data:

Abundance of 1st isotope  = 99.63%

Atomic mass of 1st isotope = 14.003 amu

Abundance of 2nd isotope  = 0.37%

Atomic mass of 2nd isotope = 15.000 amu

Solution:  

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass = (99.63×14.003)+(0.37×15.000) /100

Average atomic mass =  1395.119 + 5.55 / 100

Average atomic mass  = 1400.67 / 100

Average atomic mass = 14.0067  amu.

What are [Ba2+] and [CrO42−] in a saturated BaCrO4 solution if the Ksp of BaCrO4 is 1×10−10?
Sholpan [36]
1)  Chemical equation of the equilibrium

BaCrO4⇄ Ba (2+) + CrO4 (2-)

2) Ksp equation

Ksp = [Ba(2+)] [CrO4 (2-)]

where Ksp = 1.0 * 10^ - 10 and [Ba(2+)] = [CrO4(2-)] = x

3) Calculations

1.0 * 10^ -10 = x * x

=> x^2 = 1.10 * 10^-10

=> x = √[1.0 * 10^ -10] = 0.000010

Answer: [Ba(2+)] = [CrO4(2-)] = 0.00001 M
