Answer:

Explanation:

7) A block of wood

has a length of 10.2

cm, a width of 6 cm

and a height of 4.1

cm. The wood has

a total mass of 179

grams. What is the

volume of the

wood and what is

the density of the

wood?

volume = L XW XH=10.2 X 6 X4.1 =250.92cm^3

DENSITY = M/V = 179gm/250.92 cm^3

=0.713 gm/cm^3

Between which of these pairs of elements is a covalent bond most likely to form?
olga_2 [115]

Answer:

The correct option here is the first option

Explanation:

Covalent bond is the bond that involves the sharing of electrons between the participating atoms. The electrons (in the outermost shells of the atoms) that are involved this sharing are called the "shared pair" while those electrons (in the outermost shells of the atoms) that are not involved in this sharing are called the "lone pair". Bonding eventually leads to each of the participating atoms achieving it's octet configuration.

Carbon will bind covalently with fluorine (to form carbon tetrafluoride) with each of the electrons on the outermost shell of the carbon been shared covalently with fluorine atoms (that also requires just one electron to achieve it's octet configuration). Thus, at the end, we would have one carbon atom being covalently linked to four flourine atoms.

describe how the current modern atomic theory and model differs from the model jj Thompson proposed ?
myrzilka [38]
J.J Thompson’s model shows a sphere with electrons that are moving around freely. However, Thompson’s model does not show protons or neutrons. The model that we have today gives a clearer structure showing protons, neutrons, and electrons inside an atom.

Which of the following energy changes occurs as a bow is drawn and released?
Nuetrik [128]
<span>3. elastic potential to kinetic
</span>Mechanical energy is the top suject while it has two types: Kinetic energy which is the energy in motion and potential energy which is the energy in reserve. The measure of both energy in motion and reserve is called Joules. Joules then is the International System of Measurement unit for energy, this is mainly used to account for scaling energy in all aspects.<span> </span>

How do mutations affect a species ability to survive and reproduce? Justify your response in two or more complete sentences.
olga nikolaevna [1]
Mutation affect a species ability to survive and reproduce. Mutations can expand the life span of a species by keeping them hidden from predators which would also increase reproduction. If exposed to other wildlife, those numbers could decrease.
