Azobisisobutyronitrile (AIBN) is commonly used as a radical initiator. Use correct arrow formalism to show this process.
Dahasolnce [82]

Answer: AIBN is good radical initiator

Explanation:

A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.

The reaction below is at dynamic equilibrium. Upper N subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper
Len [333]

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

Let's consider the following reaction at equilibrium.

N₂(g) + 3 H₂(g) = 2 NH₃(g)

<h3>What is the chemical equilibrium?</h3>

Is a state in which the concentrations of reactants and products are constant and the forward reaction rate and constant reaction rate are equal.

<h3>What is the equilibrium constant?</h3>

The equilibrium constant (K) is the ratio of the concentrations of the products to the concentrations of the reactants, all raised to their stoichiometric coefficients.

Let's consider which statement is true for the equilibrium system.

  • The concentration of NH₃ is greater than the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.
  • The concentration of NH₃ equals the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.
  • The rate of the forward reaction equals the rate of the reverse reaction. TRUE. This is always true for a reaction at equilibrium.
  • The rate of the forward reaction is greater than the rate of the reverse reaction. FALSE. At equilibrium, both rates are equal.

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

7.The equation below shows a process that occurs in all green plants.
pychu [463]

Answer:

Ⓓ The process follows the law of conservation of mass and energy is found in the product

Explanation:

This question depicts PHOTOSYNTHESIS, which is the process employed by green plants to manufacture their food in form of sugars (glucose). The general equation, which was given in the question is as follows:

6CO2 + 6H2O + energy → C6H12O6 + 6O2

This chemical reaction follows the LAW OF CONSERVATION OF MASS, which states that the amount of matter in reactant must equate that of the product. In this case, each element contains the same number of atoms in both reactant side and product side.

Also, energy is contained in the product but stored in the chemical bonds of the glucose molecule formed.

Which of the following observations indicates that an atom has neutrons?
olganol [36]

Answer:

The correct answer is C: A radiation consisting of uncharged particles is emitted when alpha particles strike beryllium atoms.

Explanation:

Chadwick discovered neutron while experimenting with a gold foil. A stream of alpha particles produced from a polonium source was directed at beryllium target. It was noticed that some penetrating radiations were produced. These uncharged particles were called neutrons because on the charge detector these particles showed no deflection.

Their nuclear reaction is as follow.

                             ₂He + ₄Be ----------> ₀n + ₆C

Chadwick noticed that neutrons cannot ionize gases and are highly penetrating particles.
