Answer:

Repeated SN2 reactions occur leading to the formation of a racemic mixture

Explanation:

S-2-iodooctane is a chiral alkyl halide with an asymmetric carbon atom. The presence of an asymmetric carbon atom implies that it can rotate plane polarized light and thus lead to optical isomerism. The two configurations of the compound are R/S according to the Cahn-Prelong-Ingold system.

However, when S-2-iodooctane is treated with sodium iodide in acetone, repeated SN2 reactions occur since the iodide ion is both a good nucleophile and a good leaving group. Hence a racemic modification is formed in the system with time hence we end up with (±)- Iodooctane.

A compound with the empirical formula, ch2, has a molar mass equal to 84.2 g/mol. what is the molecular formula for the compound

MatroZZZ [7]

<span>Mass of CH2 = 12 + 2 = 14 g/mol The number of CH2s there are. So since the total mass is 84.2 g/mol. The solution is 84.2/14 = 6.012 thus the answer is 6 There are 6(CH2) So the molecular formula is C6H12</span>

When an object transfers energy to another object, does it always transfer all of it’s energy?

valentinak56 [21]

Answer:

Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.

an ideal gas is at a pressure 1.00 x 10^5 N/m^2 and occupies a volume 11.00 m^3. If the gass is compressed to a volume of 1.00 m

bogdanovich [222]

Answer:

$P_2=1.1x10^6Pa$

Explanation:

Hello.

In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:

$P_1V_1=P_2V_2$

In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:

$P_2=\frac{P_1V_1}{V_2}$

Consider that the given initial pressure is also equal to Pa:

$P_2=\frac{1.00x10^5Pa*11.00m^3}{1.00m^3}\\ \\P_2=1.1x10^6Pa$

Which stands for a pressure increase when volume decreases.

Regards.

A general change, such as increasing or decreasing numbers

Blababa [14]

c)pattern

Explanation:

A general change such as increasing or decreasing numbers is called a pattern. A pattern shows a structured way of implementing a change.

Patterns can be a form of increment in values by adding a particular number at intervals.
It can be a division, multiplication or subtraction of a consistent number.
Patterns can provide insight into understanding a number system or a group of numbers.
Sequences are usually derived from patterns.
