Explanation:
is an electron donating group which directs the electrophile to meta position reduction of nitro group with
produces amine.
Acylation of amine with
produces required product.
The complete reaction is as follows.
Answer:
so first what you would do is the first questions asking what is the average mass of the fruits! so in my head im looking at the graph and go i would add up all the fruits MASS make sure to add the mass only and get the total of the mass that all the fruits have. the seconed question is asking what is the average cost of the first purchase? look at the graph it says the first fruit cost 1.37 dollars. the third and last question is calculate the average cost per mass of the fruit purchassed. so this is a tricky one but ill help you what i think would take the cost of the fruit and divide it by the mass of each fruit! i hope tis helps you can do this! i can also say that question two is trying to make you think over it so dont its litteraly stated to you on the graph lol
Explanation:
Answer:
Because the amount of water must be measured with precision.
Explanation:
Hello!
Adiabatic calorimeters are used to measure the amount of heat absorbed or transferred during a chemical reaction.
When using the calorimeter, the reagent masses must be accurately measured to avoid errors in the calculations.
