The mechanism for the reaction of the alkene side product with concentrated hydrochloric acid cannot easily abstract proton to form alkene.
We do not observe alkene side product because Cl- (chloride) is a poor base which cannot easily abstract proton to form alkene.
For obtaining alkene as product, Sulphuric acid H₂SO₄ is used.
Hydrochloric acid, additionally called muriatic acid, is an aqueous answer of hydrogen chloride. it is a drab solution with a specific pungent smell. Hydrochloric acid, additionally known as muriatic acid, is an aqueous solution of hydrogen chloride. Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (quick-term) inhalation publicity may also purpose eye, nostril, and breathing tract irritation and infection and pulmonary edema in humans.
A reaction mechanism is the collection of standard steps with the aid of which a chemical response occurs. A reaction that occurs in or greater elementary steps is known as a multistep or complex response. A response intermediate is a chemical species that is fashioned in a single essential step and ate up in a subsequent step.

Hello!
Answer: 14.3%
Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound.
In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen.
Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.
Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.
So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%
Hope this Helps! Have A Wonderful Day! :)
Answer: 8.59 L of oxygen gas are needed to produce 100 kJ of energy at STP
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atmosphere respectively.
1 mole of every gas occupy volume at STP = 22.4 L
The balanced chemical reaction is:
3909.9 kJ of of energy is produced by = 
100 kJ of oxygen gas are needed to produce =
