Answer:

SN2 mechanism

Explanation:

This is a situation were substitution occurs with inversion of configuration at the chiral centers which proceed through concerted backside attack where nucleophile approaches the alkyl halides 180° from c-br bond, as c-(nucleophile) bond forms , the c -(leaving group) bond breaks.

Answer:

The mechanism is most likely to be SN2.

Explanation:

SN1 reaction is a two step reaction in which the first step is carbocation formation which is planar.The nucleophile can attack from either sides of it resulting in recemic mixture(both retention and inversion product is formed).

But SN2 reaction is a single-step process that is the leaving group leaves and the nucleophile attacks at the same instant.Hence the nucleophile attacks from the opposite side of the leaving group resulting in inversion product.

Hence mechanism is SN2.

The volume of a gas at 99.6 kPa and 24°C is 4.23 L. What volume will it occupy at 93.3 kPa ?
yuradex [85]

The volume is increased to 4.52 L on decreasing the pressure to 93.3 kPa.

Explanation:

As per Boyle's law, the volume occupied by gas particles will be inversely proportional to the pressure experienced by those particles at constant temperature.

V=\frac{1}{P}

So in the present problem, the volume of gas at pressure P₁ = 99.6 kPa is given as V₁ = 4.23 L. The temperature is kept constant at 24°C. Then, if the pressure is decreased to 93.3 kPa, then the volume is tend to increase due to Boyle's law.

So let us consider the new pressure be P₂ = 93.3 kPa and the new volume has to be found.

Then using Boyle's law, P_{1} V_{1} = P_{2}  V_{2}

Then, V_{2}=\frac{P_{1} V_{1} }{P_{2} }

So, V_{2}=\frac{99.6*1000*4.23}{93.3*1000}=4.52 L

Thus, the volume is increased to 4.52 L on decreasing the pressure to 93.3 kPa.

The number of atoms in 2 moles of aluminium is if the 1mole is 6.022*10 the power of 23 or 10^23
patriot [66]

Answer:

1.204 × 10²⁴ atoms

Explanation:

According to this question, one mole of aluminum (Al) atom contains 6.02 × 10²³ atoms.

If two moles of aluminum are given, this means that there will be 2 × 6.02 × 10²³ atoms of aluminum

2 × 6.02 × 10²3

= 12.04 × 10²³

= 1.204 × 10²⁴ atoms.

Why does a balloon which is filled with cold air sink in water​
Strike441 [17]

Cold air doesn't cause latex helium balloons to deflate, but it does make helium molecules lose energy and move closer together. This decreases the volume inside the balloon and makes the shell of the balloon shrink and sink to the ground.
