If an electron is transferred from A to B in the chemical reaction shown here,
what molecule has been reduced?
AB
A+
A
B

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

Purview is the word that best replaces reach without changing the meaning of the sentence. Therefore, the correct option is option B.

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.

Therefore, the correct option is option B.

A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.

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.

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 57.6 g

volume = 40.25 cm³

We have

[tex]density = \frac{57.6}{40.25} \\ = 1.431055900...[/tex]

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.

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.

Answer:

The rapid motion and collisions of molecules with the walls of the container causes pressure (force on a unit area). Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure

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

Explanation:

Filtration is a process that is use to separate insoluble solid from liquid for example Salt and water.

This process uses filter paper which is placed inside a funnel and then placed inside a beaker.

The mixture of sand and water is poured into the the filter paper and water then drains out down to the funnel and the beaker.

The solid part remain at the filter paper and it is called the residue and the water is the filtrate.

Aldehydes 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
