What is a convection cell 12 points

The answer is "opposite charges."

Final answer:

When clothes are removed from the dryer and cling together, it is because static electricity is created from the clothes rubbing together in the dryer. This results in an imbalance of electrical charge on the clothes, with some having a net positive charge and others a net negative charge, which makes them attract and stick to each other.

Explanation:

When clothes are removed from the dryer and they cling together, this is due to the presence of static electricity. Static electricity occurs when materials are rubbed together, causing an exchange of electrons. This exchange results in the materials being electrically charged. In the case of your dryer, the process of tumbling and rubbing the clothes together can strip electrons from the clothes and deposit them on other pieces.

This creates an imbalance in charge, leading to some clothes having a net positive charge and others with a net negative charge. The positively charged clothes are attracted to the negatively charged ones, and this attraction causes the clothes to stick together. The force that brings these different charged clothes together is called electrostatic force. If the clothes are damp, the presence of water molecules can suppress the charge, reducing the static cling.

Answer:

The most commonly found element in the earth's crust is Oxygen.

Explanation:

The atomic umber of Oxygen is 8.The electronic configuration of oxygen is 2,6.It belongs to the chalcogen family in the periodic table.It is a strong oxidizing agent and highly reactive non-metal.The amount of oxygen present in the earth's crust is 46.6%.The oxygen exists in two forms ,they are (oxygen) and (ozone).The major compound of it exists in the form of silicate minerals where it combines with other minerals.It also exists i the compound as carbonates and phosphates. Oxygen with acetylene is used to cut and weld the metals.In the medical field,Oxygen is used to ease the respiratory disease and it is also used to manufacture the the explosives.

Answer:

water/h20

Explanation:

the earth is mostly contained of water

Answer:

Explanation:

The formula of water is H₂O.

1. Calculate the molar mass of water

2 H = 2 × 1.008 =   2.016 u

1 O = 1 × 16.00  = 16.00   u

                  MM = 18.02    u

2. Mass of hydrogen

\text{Mass of H} = \text{92.0 g water} \times \dfrac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g H}

3. Mass of 0xygen

Final answer:

A 92 gram sample of water will consist of approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.

Explanation:

Water

consists of two hydrogen atoms and one oxygen atom. Therefore, it has a

molecular formula of H2O

. To find the mass of each element in a 92 gram sample, we need to know the molar mass of the elements and the compound. The molar mass of hydrogen (H) is about 1 gram per mole, and oxygen (O) has a molar mass of 16 grams per mole. So, the molar mass of water (H2O) is approximately 18 grams per mole (2*1 + 16). This means that in one mole of water, 2 grams are hydrogen and 16 grams are oxygen. If we scale this up to 92 grams, we find that there are approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.
