Answer: Option (a) is the correct answer.

Explanation:

A chemical reaction is the reaction that involves gain and loss of electrons due to which there is formation of new compounds or products.

Foe example, HCl + NaOH \rightarrow NaCl + H_{2}O

That is, in chemical reactions change in oxidation state of reactants occur.

Hence, we can conclude that out of the given options electrons participates in chemical reactions.

I think the correct answer is electrons. All chemical reactions are dependent on the transfer of electrons. Other subatomic particles are located in the innermost portion of an atom and are bonded strongly with each other.

Answer:

balanced;

unbalanced;

unbalanced;

balanced;

Explanation:

CaO + 3C → CaC2 + CO  //all elements are balanced

Na + H2O → 2NaOH + H2  //Na is not balanced on the left

4Fe + O2 → 2Fe2O3  //O is not balanced on the left

2Mg + O2 → 2MgO //left is equal to right, balanced

The activation energy for the reaction NO2 (g )+ CO (g) ⟶ NO (g) + CO2 (g) is Ea = 218 kJ/mol and the change in enthalpy for the
madreJ [45]

Answer:

470\frac{KJ}{mol}

Explanation:

The activation energy represents the energy barrier that reagents must pass to transform into products (or products to transform into reagents in a reverse reaction)

For any reaction, the change in enthalpy is related to the activation energy by the equation

\Delta H =E_{a\ direct}-E_{a\ reverse}

So, the activation energy for the reverse reaction is

E_{a\ reverse}=E_{a\ direct}-\Delta H =218 \frac{KJ}{mol} - (-252)\frac{KJ}{mol}=470\frac{KJ}{mol}
