what is the role of the sun in forming convection currents in earths water and air?use scientific reasoning to construct your answer.

Answers

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.

Which property of a substance can be determined using a pH indicator ?

Answers

The answer is acidity, because pH indicators help indicate the H+ or OH- concentration in a solution. H+ concentrations create acids, and OH- make bases. pH indicators don’t indicate any of the other answers in the question, so the answer is Acidity.

what is the difference between simple distillation and fractional distillation

Answers

Answer:

Fractional distillation is essentially the same as simple distillationexcept that a fractionating column is placed between the boiling flask and the condenser. The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled.

Explanation:

Answer:

Explanation:

The difference between simple and fractional distillation is the number of times that the liquid is vaporized and condensed. Simple distillation condenses the liquid once, so the boiling points of the two liquids must be far apart to make it efficient. The number of simple distillations in a fractional distillation apparatus depend on the length and efficiency of the fractionating column. The process is the same; the difference is mainly one of iteration.

An unknown element has two isotopes. The first isotope has a mass of 68.926 amu and an abundance of 60.108%. The second isotope has a mass of 70,925 amu and an abundance

Explanation:
To find the average atomic mass (

A
r
by its percentage that is expressed as a decimal and total the results. We can carry this out in a single line of working:

Similarly, you could input the percentages normally and then divide by

Notice that the answers are the same. Also observe that the answer is closer to 69 than it is to 71, which makes sense since gallium-69 makes up a greater proportion of gallium in the universe (

Answer to the correct number of sigtigs including units in your answer.
(to receive full credit, work must be submitted for this question)

Answers

Answer:

153.6771 amu

Explanation:

From the question given above, the following data were:

Isotope A:

Mass of A = 114.3789 amu

Abundance (A%) = 64.23%

Isotope B:

Mass of B =.?

Abundance (B%) = 100 – A%

Abundance (B%) = 100 – 64.23

Abundance (B%) = 35.77%

average atomic mass of Element Y = 128.4359 amu

The mass of the 2nd isotope (i.e isotope B) can be obtained as follow:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]

128.4359 = [(114.3789 × 64.23)/100] + [(Mass of B × 35.77) /100]

128.4359 = 73.4656 + (Mass of B × 0.3577)

Collect like terms

128.4359 – 73.4656 = Mass of B × 0.3577

54.9703 = Mass of B × 0.3577

Divide both side by 0.3577

Mass of B = 54.9703 / 0.3577

Mass of B = 153.6771 amu

Therefore, the mass of the 2nd isotope is 153.6771 amu
