The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.

Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.

Which technique is likely to have less of an impact on the environment?

Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

Nitrogen has an atomic number of 7. Its atomic mass is 14. Nitrogen has _____.

seven electrons
seven neutrons
seven electron shells
23 neutrons
14 electrons

Please help (:

Answers

Seven electrons. The atomic number of a element is also the amount of protons and electrons it has.

As atomic Number is number of protons Or number of electrons so
N has 7 electrons
Neutrons= Mass no.- Atomic Number
= 14-7
N has 7 neutrons
N doesn’t have 7 electron shells because shell 1 can hold 2 electrons and shell 2 can hold 8 electrons
It doesn’t have 23 neutrons and 14 electrons

So, Seven Electrons and seven neutrons is correct

why is compound not a mixture?

Answers

Compound is a pure substance containing two or more elements that are chemically combined in a fixed ratio but mixture is made up of two or more substances that are not chemically combined.

The way my chemistry professor explained it was compounds are from the same side (nonmetals), so they don’t necessarily mix well. It would be different if it was an ionic bond, because ionic bonds are when metals and nonmetals mix.

In a moment, he said, he would ask the present company to drink a toast. But before doing so, there were a few words that he felt it incumbent upon him to say.It was a source of great satisfaction to him, he saidand, he was sure, to all others presentto feel that a long period of mistrust and misunderstanding had now come to an end. There had been a timenot that he, or any of the present company, had shared such sentimentsbut there had been a time when the respected proprietors of Animal Farm had been regarded, he would not say with hostility, but perhaps with a certain measure of misgiving, by their human neighbours. Unfortunate incidents had occurred, mistaken ideas had been current. It had been felt that the existence of a farm owned and operated by pigs was somehow abnormal and was liable to have an unsettling effect in the neighbourhood. Too many farmers had assumed, without due enquiry, that on such a farm a spirit of licence and indiscipline would prevail. They had been nervous about the effects upon their own animals, or even upon their human employees. But all such doubts were now dispelled. Today he and his friends had visited Animal Farm and inspected every inch of it with their own eyes, and what did they find? Not only the most up-to-date methods, but a discipline and an orderliness which should be an example to all farmers everywhere. He believed that he was right in saying that the lower animals on Animal Farm did more work and received less food than any animals in the county. Indeed, he and his fellow-visitors today had observed many features which they intended to introduce on their own farms immediately.What results from the human farmers visit to Animal Farm?
