Answers
Answer: C
Explanation:
The N2 should have a triple bond because it needs three covalent bonds to fill its outer shell. This means the two atoms need to share three electrons each.
It also serves as a nice illustration of a triple-bonded molecule. For the Lewis structure of N2, there are ten accessible valence electrons. Therefore, option C is correct.
What is lewis structure ?The diagrams known as Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.
It contradicts the octet rule, as shown by the production of molecules, and could not account for the release of energy during the formation of covalent bonds.
The three parallel lines between the N atoms represent three bonds. This is a triple bond, with one electron from each N atom contributing to each bond. A total of 6 electrons are thus represented by this triple bond.
Thus, option C is correct.

_________energy is stored in chemical bonds.
Answers
Answer:
Chemical energy is the potential energy stored in the arrangement of atoms within molecules. Breaking chemical bonds requires energy, while forming new chemical bonds releases energy. The more energy that's released when a bond forms, the more stable that bond is.
Explanation:
1.) Nonmetallic elements form ions by (Losing/Gaining) valence electrons in order to complete their outer shell. 2.) The (Fewer/More) valence electrons an element has in its outer shell, the easier it is to complete. 3.) The (FewerMore) electron shells an element has, the easier it is to fill its outermost shell. 4&5.)Reactivity in nonmetals (Increases/Decreases) as you go from left to right in a group, and (Increases/Decreases) as you go from top to bottom.
Answers
Answer:
1) Gaining
2) More
3) More
4) increases
5) decreases
Explanation:
Nonmetals are found towards the right hand side of the periodic table. They form ions by gaining electrons due to the fact that they have more electrons in their outermost shell, hence they only need a few electrons to complete the octet structure.
As the number of shells increases, the outermost shell becomes more populated and easier to fill with electrons.
The reactivity of nonmetal elements generally increases from left to right across the periodic table but decreases from top to bottom down the group.
Answer:
1) Gaining
2) More
3) fewer
4) increases
5) decreases

A sample of ink is put in the center of filter paper . Several drops of ethanol are then put on the ink mark. Two concentric rings of circle are obtained. What is the best conclusion about the ink we can come to? a. It contains two colored substance only b. It contains at least two coloured substances c. It is a compound d. It is broken down by ethanol
Answers
Answer:
The correct option is;
b. It contains at least two colored substances
Explanation:
In chromatography, a mixture is separated into its components, such that in the filter paper, on which the drops of ethanol are then placed on the ink mark, we have different phases of the components of the mixture that have different levels of mobility by capillary action through the filter paper. Therefore, given that two concentric rings of circles are obtained, we have that each ring is composed of a different component of the mixture and there are therefore, at least two colored substances.

different arrangements to form
new substances.
Answers
Answer:
Explained below
Explanation:
In chemistry, the process of a chemical change is when the atoms from the reactants rearrange themselves and bond together differently to form one or more new substances with different characteristics than the reactants. Now, after this new substance is formed, the change is called a chemical change.
Now, in cooking Food will undergo a chemical change as it is being cooked. For example, when we boil brown meat, we are causing reactions that change the chemical composition in ways that enhance flavors. Proteins and fibers such as beans when cooked are broken down or undergo denaturation thereby making digestion easier when eaten. Fats like cooking oils are melted while Eggs when boiled are coagulated.
