The correct subscript for the reaction would be two. Oxygen gas exists as a diatomic molecule in nature. Also, the subscript two would balance the reaction. In balancing reactions, it is important that the atoms on each side of the reaction is equal.
Answer:
The activation energy is 7.11 × 10⁴ J/mol.
Explanation:
Let's consider the Arrhenius equation.
where,
k is the rate constant
A is a collision factor
Ea is the activation energy
R is the ideal gas constant
T is the absolute temperature
The plot of ln k vs 1/T is a straight line with lnA as intercept and -Ea/R as slope. Then,
Neutralization reaction means the reactants must be one acid and one alkali, and the product will be H2O and metal salt.
The only one satisfying this will be B
In a sample liquid water, a property that differs among the
water molecules is its own orientation and space. The explanation of the answer
to the question is because the number of the oxygen and hydrogen atoms and the
hydrogen and atoms’ arrangement will never change and will always be the same
for each of the water molecule. The strength of the bond of it also does not
change and stays the same.
