What is the general form of a chemical reaction

Chemistry
1 answer:
Eddi Din [679]3 years ago
4 0
So there are basically five types of chemical reactions which have their general formulas.

They are:
1. Combination reaction
General formula : A+B = AB

2. Decomposition reaction
General formula: AB = A+B

3. Single displacement reaction
General formula: AB+C = CB + A

4. Double displacement reaction
General formula: AB+CD = CB+AD

5. Acid-base reaction
General formula: A+B = S+W


You should check and compare with examples.

A _____________reaction mechanism involves loss of a leaving group, formation of a ________ followed by the removal of a proton
Molodets [167]

Answer:

The correct answer is Option C (E1) and Option B (carbocation).

Explanation:

  • Intramolecular immunity idols are considered as that of the formation mechanism with E1 responses or reactivity.
  • Reactants with E1 were indeed obligations of both parties, meaning that an E1 reaction was conducted thru all the two stages known as ionization but rather deprotonation. Involves the absence of either an aromatic ring, a carbocation has been generated throughout the ionization solution.

Some other possibilities offered aren't relevant to the procedure outlined. So the above alternative is accurate.

Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation. 2H202(aq)
inn [45]

Answer : The temperature for non-catalyzed reaction needed will be 456 K

Explanation :

Activation energy : The energy required to initiate the reaction is known as activation energy.

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

Since, the rate for both the reaction are equal.

K_1=K_2

A\times e^{\frac{-Ea_1}{RT_1}}=A\times e^{\frac{-Ea_2}{RT_2}}

\frac{Ea_1}{T_1}=\frac{Ea_2}{T_2} ..........(1)

where,

Ea_1 = activation energy for non-catalyzed reaction = 75 kJ/mol

Ea_2 = activation energy for catalyzed reaction = 49 kJ/mol

T_1 =  temperature for non-catalyzed reaction = ?

T_2 = temperature for catalyzed reaction = 25^oC=273+25=298K

Now put all the given values in the above formula 1, we get:

\frac{Ea_1}{T_1}=\frac{Ea_2}{T_2}

\frac{75kJ/mol}{T_1}=\frac{49kJ/mol}{298K}

T_1=456K

Therefore, the temperature for non-catalyzed reaction needed will be 456 K

does anyone know how to find the electron configuration of an element without using a periodic table?? group and period is alrea
snow_lady [41]
For that you have to use the Aufbau principle

For example, writing the electronic configuration of Fe(28)

I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
