Question 4 5 pts
What are the formulas of the major species present in a mixture of HNO3 and HF in water?
O HNO3(aq) + HF(aq)
O HNO3(aq) + H+ (aq) + F(aq)
OH(aq) + NO3(aq) + F (aq)
OH(aq) + NO3 (aq) + HF(aq)
O H2(g) + NO3- (aq) + F* (aq)

H(aq) + NO3 (aq) + HF(aq)

Explanation:

In the given mixture of HNO3 (Nitric Acid) and HF (hydrofluoric acid) in water  the major species present are H(aq) + NO3 (aq) + HF(aq).

On the reaction of  HNO3 (Nitric Acid) and HF (hydrofluoric acid) in water  , it will give a polar solution and will form a homogenous mixture.

Hence, the correct answer is "H(aq) + NO3 (aq) + HF(aq)".

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
