Explanation:
Because im pretty sure the molecules would just fall apart like salt which is ionic
Answer:
The simplified expression for the fraction is 
Explanation:
From the given information:
O3* → O3 (1) fluorescence
O + O2 (2) decomposition
O3* + M → O3 + M (3) deactivation
The rate of fluorescence = rate of constant (k₁) × Concentration of reactant (cO)
The rate of decomposition is = k₂ × cO
The rate of deactivation = k₃ × cO × cM
where cM is the concentration of the inert molecule
The fraction (X) of ozone molecules undergoing deactivation in terms of the rate constants can be expressed by using the formula:
since cM is the concentration of the inert molecule
According to VSEPR theory, the structure of the ammonia molecule, NH3, is linear.
So your answer is B) linear
Strong acids are those that dissociate completely into their ions. So the dissociation equation for a strong acid is:
HA → H⁺ + A⁻
It is visible from the equation that the number of moles of hydrogen ions released is equivalent to the number of moles of acid. For a given volume,
[HA] → [H]⁺ + [A]⁻
Thus, the assumption is logical and fairly accurate
