Answer: My guess is D i hope this is right
Explanation:
Answer:
II
Explanation:
We must have a good idea of the fact that there are two mechanisms that come into play when we are discussing about the addition of hydrogen halides to alkenes. The first is the ionic mechanism and the second is the radical mechanism.
The ionic mechanism is accounted for by the Markovnikov rule while the radical mechanism occurs in the presence of peroxides and is generally referred to as anti Markovnikov addition.
The intermediate in anti Markovnikov addition involves the most stable radical, in this case, it is a tertiary radical as shown in the images attached. The most stable radical is II hence it leads to the major product shown in the other image.
<h3><u>Answer;</u></h3>
El Nino
<h3><u>Explanation</u>;</h3>
- El Nino is a weather pattern that begins as a result in an increase in the water temperature at the surface of the Pacific ocean that produces a warm current.
- It is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
- It has an impact on ocean temperatures, the speed and strength of ocean currents together with the health of coastal fisheries. Its events occur irregularly at two- to seven-year intervals.
Increasing the surface area of the reactant by pelletizing the calcium carbonate, and increasing the concentration of hydrochloric acid resulted in increase in the rate of reaction.
<h3>What is reaction rate?</h3>
Reaction rate refers to the rate at which reactant molecules are consumed or the rate at which product molecules are formed.
The factors that affect reaction rate include:
- Temperature
- Concentration
- Surface area of reactants
- Nature of reactants
- Presence of catalysts
Given an experiment to determine effect of surface area of reactants and concentration on reaction rate of dilute hydrochloric acid and calcium carbonate:
It was observed that increasing the surface area of the reactant by pelletizing the calcium carbonate and increasing the concentration of hydrochloric acid made the reaction proceed faster.
In conclusion, reaction rate increases with increase in surface area.
