Answer: 3.5 moles of hydrogen gas will be produced.
Explanation:
The balanced chemical equation is:

As HCl gets completely used up,
is the limiting reagent.
According to stoichiometry :
6 moles of
produces = 3 moles of
Thus 7.0 moles of
produces=
of
Thus 3.5 moles of hydrogen gas will be produced.
Water behaves as a base in this reaction.
The Bronsted-Lowry definition is applied, because the reaction involves the transfer of H+ from one reactant to the other.
A Bronsted-Lowry base is defined as a substance that accepts a proton.
Because water gains a proton to form H3O+ in this particular reaction, it acts as a base
Answer:
Option D describe the best this statement .

As velocity is the quantity which includes the rate of change as well as direction
<u><em>Answer:</em></u>
- The correct structure of phosphoric acid is A.
<u><em>Explanation</em></u>
- P should form five covalent bonds. In this strcuture P form three single bond with 3-hydroxyl groups while one single bondformed with oxygen. As oxygen will form two bonds , it carry negative charge, while P should form five bond but here it is forming 4 bonds due to this P has positive charge but overall structure contain neutral charge due to cancellation of positive and negative charges. Beside this, there are 3 H, Four O and One P according to formula H3PO4.
