The factors that play the role in success is solvent, concentration of nucleophile and the substrate.

What is S_{N}2 reaction ?

When sp^{3} hybridized  carbon containing a leaving group and nucleophile attack from the remote side of the leaving group then the reaction is known as S_{N}2 reaction.

Factors depending on S_{N}2 reaction:

  1. Solvent: Polar aprotic solvents are very useful for this reaction as they increase the intermediate concentration and also solvate the nucleophile.
  2. Nucleophile: More strong the nucleophile  more is the rate of reaction.
  3. Substrate:1°  substrate react faster than 2° than 3°

Calculate the number of hydrogen atoms in 33.0 g CH4
Elena-2011 [213]

Answer:

The number of hydrogen atoms is 4.96x10²⁴.

 

Explanation:

The number of atoms can be found with the following equation:

n = N*\eta_{H}

Where:

N: is the Avogadro's number = 6.022x10²³ atoms/mol

η: is the number of moles of hydrogen

n: is the number of hydrogen atoms

First, we need to find the number of hydrogen moles. The number of moles of CH₄ is:

\eta_{CH_{4}} = \frac{m}{M}

Where:

m: is the mass of methane = 33 g

M: is the molar mass of methane = 16.04 g/mol                      

\eta_{CH_{4}} = \frac{33 g}{16.04 g/mol} = 2.06 mol

Now, since we have 4 hydrogen atoms in 1 mol of methane, the number of moles of hydrogen is:

\eta_{H} = 2.06\: mol\: CH_{4}*4 \frac{mol\: H}{mol \: CH_{4}} = 8.24 mol

Hence, the number of hydrogen atoms is:

n = N*\eta_{H} = 6.022 \cdot 10^{23} \: atoms/mol*8.24 mol = 4.96 \cdot 10^{24} atoms

Therefore, the number of hydrogen atoms is 4.96x10²⁴.

I hope it helps you!

A 32.5 g iron rod, initially at 22.4 ∘C, is submerged into an unknown mass of water at 63.0 ∘C, in an insulated container. The f
a_sh-v [17]

Answer:

m_{H_2O}=39.0g

Explanation:

Hello,

In this case, is possible to infer that the thermal equilibrium is governed by the following relationship:

\Delta H_{iron}=-\Delta H_{H_2O}\\m_{iron}Cp_{iron}(T_{eq}-T_{iron})=-m_{H_2O}Cp_{H_2O}(T_{eq}-T_{H_2O})

Thus, both iron's and water's heat capacities are: 0.444 and 4.18 J/g°C respectively, so one solves for the mass of water as shown below:

m_{H_2O}=\frac{m_{iron}Cp_{iron}(T_{eq}-T_{iron})}{-Cp_{H_2O}(T_{eq}-T_{H_2O}} \\\\m_{H_2O}=\frac{32.5g*0.444\frac{J}{g^0C}*(59.7-22.4)^0C}{-4.18\frac{J}{g^0C}*(59.7-63.0)^0C} \\\\m_{H_2O}=39.0g

Best regards.
