Answer:
C) Reactants absorb a minimum amount of energy and then release a smaller
amount of energy as products form.
Explanation:
The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
In an endothermic change, heat is absorbed from the surrounding.
- As such, the surrounding becomes colder at the end of the reaction.
- On a graph of an endothermic reaction, the reactants absorbs a minimum energy.
- As the reaction proceeds, the products gives off an even lesser amount of energy.
Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c: A α b · c. The proportionality constant is sometimes given the symbol a, giving Beer's law an alphabetic look: A = a · b · c.
Answer:
The usage is explained below
Explanation:
Amines are identified from the use of the hinsberg reaction whereby the amine is mixed well with Hinsberg reagent and done in the presence of an aqueous alkali. In this reaction, the amine will attack the electrophile which will result in the chloride being displaced and the amides being generated.
The uses of identification of amines in daily life are;
- In agriculture, it serves as a good source of making herbicides as well as acting as emulsifiers.
- In medicine, it is used in the manufacture of some popular pain killers like demerol and morphine.
- In medicine, it is used in the manufacture of an anesthetic drug known as novocaine.
- In chemical industries, amines are used as lubricating oils and also as corrosion inhibitors in boilers.
The answer you're looking for is B. The bond will be ionic.
