It has a decrease in oxidation number

The process of reduction is when the oxidation number of a chemical specie is lowered, or when the specie gains electrons. A chemical specie undergoing reduction will act as an oxidizing agent, because it will oxidize the other reactant by itself getting reduced.

Write out the mechanism for the reaction of the alkene side product with concentrated hydrochloric acid.
Marrrta [24]

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! :)

How many liters of oxygen gas (O2) are needed to produce 100 kJ of energy at STP? 2C6H6(I) + 1502(g) —> 12CO2(g)+6H2O(g)+3909
makkiz [27]

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 6.023\times 10^{23} 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:

2C_6H_6(I)+15O_2(g)\rightarrow 12CO_2(g)+6H_2O(g)

3909.9 kJ of of energy is produced by  = 15\times 22.4=336L

100 kJ of oxygen gas are needed to produce = \frac{336}{3909.9}\times 100=8.59L
