Explanation: Some examples of atoms with nonpolar convalent bonds. Hope this was found useful!!
Non polar covalent compounds have no net dipole moment due to charge separation. Some examples are, CO₂, H₂, N₂,O₂ etc.
What are covalent compounds?Covalent bonds are formed by the sharing electrons between atoms. Covalent bond is comparatively weaker than ionic bonds. Atoms of deficient number of electrons will combine by sharing their valence electrons and forms covalent bonds.
When one atom has more electronegativity, then the shared pair of electrons will attracted into the electronegative atom. This creates a charge separation and a dipole moment.
However, if the electronegative atoms are linear in geometry from the central less electronegative atom then the dipole moment cancel each other and the compound become non polar as in the case of CO₂.
All gases in molecular states are covalently bonded and are non polar such as H₂, N₂,O₂ etc.

What is the total number of carbon atoms in 10C4H10?
Answer:
40 C atoms
Explanation:
Step 1: Write organic compound
10C₄H₁₀
We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.
We are given that we have 10 moles of C₄H₁₀.
Therefore, we have 4 · 10 = 40 atoms C

The atomic radius of magnesium is 150 pm. The atomic radius of strontium is 200 pm. What is the atomic radius of calcium
Answer:
The atomic radius of calcium is approximately 175
Explanation:
Given that the atomic radius of magnesium = 150 pm
The atomic radius of strontium = 200 pm
Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity
Therefore;
The atomic radius of calcium is approximately given as follows;
The approximate atomic radius (200 + 150)/2 = 175 pm.

A proton is a subatomic particle carrying a charge equal to but opposite that of an electron
true
false
Answer:
True
Explanation:
A proton has a charge of +1, while an electron has a charge of -1. This is why a neutral atom has the same number of protons as electrons.
Neutrons have no charge, hence their name neutron which is similar to neutral.

If an egg is placed in a container of salt water, the mass of the egg will decrease because water will move out of the egg. What process does this represent?
Osmosis
Mitosis
Respiration
Fermentation
Answer:
osmosis. I
Explanation:
If an object/ cell is placed in a solution where the concentration is more or stronger than itself(hypertonic solution), it shrinks because water moves out of it, but if it is placed where the concentration of the surrounding solution is lesser than its concentration(hypotonic solution), it swells and can burst because water moves into it. So the mass of the egg will decrease because it is placed in an hypertonic solution (salt water) and the concentration of the salt water is stronger than its concentration

O
true or false.
True
Further explanationAldehydes are alkane-derived compounds containing the functional group (-CO-) located at the end of the parent carbon chain
The general structure is R-CHO with the molecular formula CnH2nO
Naming is generally the same as the alkane by replacing the suffix with -al
Acetaldehyde(ethanal) is an aldehyde which has 2 C atoms with formula

The bond between the C atom and the O atom is a double bond
So the C atom has a single bond with H and alkyl and double bonds with O

How many grams of Sodium will have the same number of atoms as 6 grams of Magnesium?
Atomic mass of Sodium is 23 u and atomic mass of Magnesium is 24 u.
Answer:
92gm
Explanation:
Atomic mass of Mg=24g=1 mole of Mg
∴ 24g =1 mole of Mg contain 6.022×10^23 atom
∴ 6gm contains 246.022×1023×6
=4×6.022×10^23 atoms
Now according to question, there are 6.022×1023 atoms of Na
23gm of Na contains 6.022×10^23 atoms
∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm

Increasing the temperature of gas in a container that cannot expand is a way to _______. decrease the volume of the gas decrease the volume of the gas increase the pressure of the gas increase the pressure of the gas decrease the pressure of the gas decrease the pressure of the gas increase the volume of the gas
Answer:
Increase the pressure of the gas
Explanation:
According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).
From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.
When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

Purview is the word that best replaces reach without changing the meaning of the sentence. Therefore, the correct option is option B.
What is statement?A sentence is indeed a collection of words used to express a thought. A sentence always begins with such a capital letter then concludes with a period, punctuation mark, and exclamation point. Ideal sentence construction has a verb and a subject. Declarative sentences make a declaration, express an opinion, or make an emotion known.
Declarative sentences have a period at the end. Questions are asked in sentences known as interrogatives. These phrases are followed by a question mark. This kind of phrase is used to give instructions or make a request. There is typically a period at the end, but occasionally there is also an exclamation point. Univocal means having only one possible meaning. Purview is the word that best replaces reach without changing the meaning of the sentence.

I have learned that the law of acceleration can be applied in the
following situations
1.
2.
3.
helpppp poooooo
Answer:
See explanation below
Explanation:
Let's recall what's the law of acceleration.
First of all, the acceleration is a vector that has the change of velocity in function of the time.
Now, the law of acceleration is related to Newton's Second law which states that an object will move only if there are forces around it. In other words, the following expression:
F = m . a
Now, in this case, we know that the acceleration of an object is affected by a force always. So, if an object stand still, it will not move unless you push it or pull it to move, and the acceleration will speed up or down depending of the force it was exerted.
According to this, the law of acceleration can be applied here:
1. A bike going down a hill. Of course, because, let's suppose you let a bike alone go down on a hill, you will see that the speed of the bike will be faster as time goes by. This is because the force acting here is the weight of the bike and gravity.
2. Dropping a ball from a building. In this case, you drop a ball from a high floor on a building, it will happen the same thing as the bike. It will go faster because of gravity.
3. Putting the break on a car. Now in this case it's easy because you only need to know that when you put the brakes, the speed of the car will go down, but also the acceleration. So there's no need of a further explanation of this.

what is the role of the sun in forming convection currents in earths water and air?use scientific reasoning to construct your answer.
Answer:
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds. I hope this helps
The sun heats the air near the equator of the earth, it becomes less dense and rises upward. As warm air rises, it cools and gets less dense than the air around it.
What is convection?Convection can be d defined as the transfer of heat from one place to another due to the movement of heat or fluid. Convective heat transfer involves the processes of conduction as well as advection.
Gases and liquids can not be good conductors of heat under normal conditions, but they can easily transfer heat.
Convection occurs through diffusion or advection but does not take place in solids, as there is no movement of its constituent particles happens. The diffusion of heat in solids is known as thermal conduction.
The heat transfer that occurs between a surface and a liquid that is in contact with the surface is convection heat transfer.
The Sun provides the energy for the convection in the ocean and produces ocean currents. There are two kinds of ocean currents: one is surface currents and the other deep currents.
