Why do the isotopes of a particular element behave differently in nuclear reactions but the same in
AfilCa [17]

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.

To calculate the enthalpy change for the reaction, 2CO (g) + O2 (g) Imported Asset 2 CO2 (g), you can use ΔHf0 values for each r
svetoff [14.1K]

Answer:

ΔH0reaction = [ΔHf0 CO2(g)] - [ΔHf0 CO(g) + ΔHf0 O2(g)]

Explanation:

Chemical equation:

CO + O₂   →  CO₂

Balanced chemical equation:

2CO + O₂   →  2CO₂

The standard enthalpy for the formation of CO = -110.5 kj/mol

The standard enthalpy for the formation of O₂  = 0  kj/mol

The standard enthalpy for the formation of CO₂  = -393.5 kj/mol

Now we will put the values in equation:

ΔH0reaction = [ΔHf0 CO2(g)] - [ΔHf0 CO(g) + ΔHf0 O2(g)]

ΔH0reaction = [-393.5 kj/mol] - [-110.5 kj/mol + 0]

ΔH0reaction = [-393.5 kj/mol] - [-110.5 kj/mol]

ΔH0reaction = -283 kj/mol
