The isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions because the nuclear reactions involve changes to protons and neutrons in an atom and isotopes differ in neutrons and so they react differently to nuclear changes. While for chemical reactions, the electrons in an atom are involved but the isotopes do not differ in electrons and so they react the same way during chemical changes.

Answer: Option A & C

<u>Explanation:</u>

The reactants of chemical and nuclear reactions are different. The reactants of chemical reactions are the electrons present in the outermost shell of the reactants, while the reactants of nuclear reactions are either the nuclei of reactants or a nuclei and any subatomic particles of other reactants.

Thus it can be understood that chemical reactions consider the electrons while nuclear reactions consider the nuclei or the number of protons and neutrons of the reactants.

The isotopes of elements contain different mass number or we can say different number of neutrons but the number of electrons are same, so they behave differently in nuclear reactions and similar in chemical reactions.

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.

The process by which plants give off water vapor into the air is

kaheart [24]

Answer:transpiration

Explanation:

The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
