To break a chemical bond, energy must be(1) absorbed (2) destroyed (3) produced (4) released

Answers

Answer 1

Answer:

Answer: 1) absorbed

Explanation:

As a chemical bond is formed either by transfer of electrons or sharing of electrons, in order to break the forces of attraction among atoms, energy must be absorbed.

Energy is produced or released when a chemical bond is formed.

Energy is never destroyed, it converts from one form to another.

Answer 2

Answer:

To break a chemical bond, energy must be $\boxed{\left( 1 \right){\text{ absorbed}}}$ .

Further explanation:

The attraction existing between atoms and molecules that facilitate the formation of various chemical compounds is termed as a chemical bond. It is formed either due to electron transference or by electron sharing between the bonded atoms. The chemical bond formed as a result of electron transfer from one atom to another is known as an ionic bond. The bond formed by the mutual sharing of electrons is called a covalent bond.

Endothermic process

The basic meaning of “endo” is “in”. These processes need energy from the surroundings, generally in the form of heat. Photosynthesis, evaporation of water, sublimation of dry ice, and melting of ice are some of the examples of endothermic processes.

Exothermic process

The general meaning of “exo” is “out”. These processes release energy from the system to the surroundings in the form of heat. Combustion of fuels, thermite reactions, nuclear reactions, and neutralization reactions are some examples of exothermic processes.

Since bond breaking is an endothermic reaction, energy must be supplied or absorbed from the surroundings to the system. Therefore, option (1) is the correct answer.

From where does the nitrogen in the nitrogen cycle originate?a. root nodules of legumes
b. the atmosphere
c. decomposers
d. nitrifying bacteria

Answers

The correct answer is B. The nitrogen in the nitrogen cycle originate from the atmosphere. It forms approximately 78% of the Earth's atmosphere. However, this form is not usable because it is in its most stable form therefore unreactive. This nitrogen gas needs to be converted into nitrate compound for it to be usable. Then, the nitrogen cycle starts.

Answer:

B) the atmosphere

Why does it make sense that if an atom loses electrons, it is left with a pisitive charage?

Answers

Because atoms are neutral. By neutral, I mean that; there are three main particles that make up an atom. Protons, Electrons and Neutrons. Protons have (electrically) positive charge, electrons have negative and neutrons are electrically neutral. One proton's charge is +1 and one electron's charge is -1. An atom (normally) has the same amount of protons and electrons. Let's say if an atom has two protons and two electrons, the sum of electrical charges of the protons is (two times +1) +2 and sum of electrical charge of electrons is (two times -1) -2 . The total charge of the atom is the sum these. So, (-2)+(2)= 0. That makes the charge of the atom 0, thus makes it neutral. But let's say this atom loses one of its electrons, and now has only one. So one electron (-1) and two protons (+2) in total will be : (-1)+(2) = +1 . +1 is positive, so this makes the charge of the atom positive.

Electrons have a net negative charge, therefore by losing them the atom will become slightly more positive.
