Answer:

8.02 g of HCl could be left over by the chemical reaction

Explanation:

We propose the reaction:

HCl(aq) + NaOH (s) → NaCl (aq) + H₂O (l)

Ratio is 1:1. First of all, we determine the moles of reactants:

14 g . 1mol / 36.45g = 0.384 mol of acid

6.55 g. 1mol / 40g = 0.164 mol of base

If a determined mass of HCl, could be left; this means that the acid is the excess reagent.

For 0.164 moles of NaOH, we need 0.164 moles of HCl.

As we have 0.384 moles, (0.384 - 0.164) = 0.220 moles of acid are left over in the reaction. We convert the moles to mass:

0.220 mol . 36.45 g /1mol = 8.02 g

The organic product formed when 1−hexyne is treated with H₂O, H₂SO₄, and HgSO₄ will be 2-hexanone (structure attached).

This reaction is an example of an oxymercuration reaction of the organic product 1−hexyne.

Oxymercuration is shown in three steps to the right. The nucleophilic double bond attacks the mercury ion, releasing an acetoxy group. The mercury ion's electron pair attacks carbon on the double bond, generating a positive-charged mercuronium ion. Mercury's dxz and 6s orbitals give electrons to the double bond's lowest unoccupied molecular orbitals.

In the second stage, the nucleophilic H₂O attacks the highly modified carbon, freeing its mercury-bonding electrons. Electrons neutralize mercury ions by collapsing. Water molecules have positive-charged oxygen.

In the third stage, the negatively charged acetoxy ion released in the first step attacks the hydrogen of the water group, generating the waste product HOAc. The two electrons in the oxygen-hydrogen link collapse into oxygen, neutralizing its charge and forming alcohol.

The formation of a gaseous product is usually indicated by a/an______________ in a chemical reaction.
Harman [31]

Answer: The formation of a gaseous product is indicated by an UPWARD ARROW in a chemical reaction.

Explanation:

A chemical reaction is defined as the process whereby chemical bonds between atoms of

substances known as reactants are either formed or broken leading to the formation of products. New substances are usually formed during a chemical reaction. The following are features of chemical reaction:

--> Evolution of gas

--> Formation of a precipitate

--> Change in color

--> Change in temperature

--> Change in state and

--> Formation of new substances.

Some chemical reactions takes place with the evolution of gas. This can be seen in the reaction of Zinc metal with hydrochloric acid. Hydrogen gas is EVOLVED with the formation of zinc chloride.

UPWARD ARROW in a chemical reaction indicates the evolution of a gas. It appears only on the product side and is written next to the gaseous product.
