Atoms of which pair of elements will form covalent bonds in a compound?
A. I and F
B. Be and CI
C. Na and Al
D. Ag and Ca

Answers

Answer:

A. I and F

Explanation:

The two element  pair that will form covalent bonds in a compound are I and F.

A covalent bond is a bond type formed between two atoms of similar electronegativity difference. In fact, the electronegativity difference between the two atoms must be very small for covalency for occur.

Therefore such bonds are notable between non-metals. From the choices given, I and F are the only non-metallic pair. Therefore, they will form a covalent bond.

Covalent bonds involves sharing of the valence electrons between two or more atoms to attain stability.

Metals are electropositive will not readily form covalent bonds.

A certain chemical contains 46.30% chlorine, 47.05% carbon, 6.63% hydrogen. What is the molecular formula of the compound? The molar mass of the compound was determined to be 153.052g/mol.

C6H10CI2
C6H8CI2
C3H5CI
C4H4CI
C8H8CI2​

Answers

Answer:

C6H10Cl2

Explanation:

Convert mass % to mass

100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H

Molar mass

Cl = 35.5 g/mol

C = 12 g/mol

H = 1 g/mol

Find the number of moles:

Chlorine: 46.4g /35.5g/mol = 1,3 moles

Carbon: 47,05g/12 g/mol = 3,92 moles

hydrogen: 6,63g/1g/mol = 6,63 moles

Molar fraction:

Cl = 1,30/ 1,30 = 1

C = 3,92/ 1,30 = 3,01

H = 6,63/ 1.30 = 5,01

C3H5Cl = 76,5 g/ mol x 2  = 153 g/ mol

So multiply the molecular formula by two = C6H10Cl2

what do igneous rocks become when they break down and settle into layers?

Answers

Answer:

Sedimentary rocks

Explanation:

Igneous rocks will become sedimentary rocks when they break down and settle into layers .

Igneous rocks are rocks that are formed by the cooling and solidification of magma within or on the earth crust.

When agents of weathering and denudation forces acts on a rock body, they break them down producing sediments in the process.

Sediments are transported into depositional basins where they are laid down and cemented together. This in turn forms sedimentary rocks. The break down and settling of sediments leads to the formation of sedimentary rocks.

A student increases the temperature of a 673 cm^3 balloon from 275 K to 460 K.

Assuming constant pressure, what should the new volume of the balloon be?

Round your answer to one decimal place.

Answers

Answer:

1125.75 cm³

Explanation:

We are given;

Initial volume; V1 = 673 cm³

Initial temperature; T1 = 275 K

Final temperature; T2 = 460 K

From Charles law, we can find the new volume from;

V1/T1 = V2/T2

V2 = (V1 × T2)/T1

V2 = (673 × 460)/275

V2 = 1125.75 cm³

Which helps regulate the temperature range of the Earth's atmosphere? Water or Land

Answers

Answer:

The oceans atmosphere. AKA Water.

Explanation:

The oceans and the atmosphere are the two large reservoirs of water in the Earth's hydrologic cycle. The two systems are complexly linked to one another and are responsible for Earth's weather and climate. The oceans help to regulate temperature in the lower part of the atmosphere.

Earth's atmosphere get warm up by the temperature absorbed by the gases in the atmosphere. However it can balanced water in earth such as ocean currents and  cooling.

What is ocean currents?

Ocean currents are formed from the pressure difference in ocean level and thus in day time there will be winds from ocean to land which cools the earth's surface.

Surface of the earth warms up by absorption of heat energy from sun. This warming will be higher if there are more greenhouse gases such as carbon dioxide, methane oxides of nitrogen, Sulphur etc.

Greenhouse gases intensely absorbs the temperature from radiation and thus increase the temperature of earth's surface. These gases are mainly evolved to the atmosphere by industries and factories.

Other factor which affects the temperature of  earth surface include wind, ocean level etc. The level of ocean and ocean currents helps to regulate the temperature of the surface  and make it cool.

Explain how Coulomb's law can help you understand why some interparticle forces are stronger than others.

Answers

Answer:

Coulombs equation involves distance and the distance from one radius to the next allows us to predict certain characteristics such as pull and attraction. For example, you would expect, a higher charge on the ion and a higher dipole moment causes a larger force. This is due to the magnitude which is the distance between these two and effectively that is how Columbus law comes into play.

Coulomb's law states that the force of repulsion or attraction among both two charged bodies is directly proportional to the product of their charges as well as inversely proportional to the square of the length between them.

What is Coulomb's law?

An electric force is created when two charged particles collide. The forces will be greater if you have larger charges.

Coulomb's Law can be understood by combining these two ideas and the fact that charges can attract and repel each other. It is a formula for calculating the electrical forces between two objects.

Coulomb's equation involves distance, and the distance between two radiuses allows us to predict certain characteristics such as pull and attraction.

As you might expect, a higher charge on the ion and a higher dipole moment result in a greater force. This is due to the magnitude of the distance between these two, and this is where Columbus law comes into play.

Thus, this way, Coulomb's law can help you understand why some interparticle forces are stronger than others.

15. In complete sentences, describe how electronegativity is related to polarity.

Answers

Explanation:

The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic.

Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

Answer:

The person above me is correct. Electronegativity relates to polarity by describing the attraction of electrons for an element. For example, Fluorine is most electronegative, so it has a high polarity. Polarity means a charge of hogging electrons. So yeah. There you go.

In 2008, more than one million American students gave nearly 20 million service hours to their communities. They made a difference in peoples lives and learned some important life lessons in the process. Organizations, including schools, are actively promoting service for all citizens as a way to be involved, help others, and improve themselves. Service is helping other people and being active in your community. For example, one group of teens planted a community garden with their friends. They grow a variety of vegetables. The garden requires regular care. The teens donate the produce to a local soup kitchen. Workers there use the produce to help feed people in the community. By tending the garden and donating their produce, the teens are actively helping make life a bit better for others in their community. Service is valuable in ways that cannot be measured in dollars. People volunteer or serve others without expecting money or gifts in return. Service is not about earning money. It is not just collecting money to give to a group. It is about action and contributing to the common good. The people who serve as well as those who receive help benefit in many ways that are more important than money or gifts. For example, a soup kitchen provides essential food to people who may otherwise go hungry. The soup kitchen is extremely valuable for those struggling to get enough to eat. Those serving learn about compassion and how helping others can improve life for all. Millions of Americans are making society better for themselves and for others. They are participating citizens in their community, raising up those who are less fortunate.
