An island is formed when magma builds up and breaks the ocean's surface. In some cases, like the island of Hawaii, land masses merge together. ... For many volcanoes, formation can take thousands of years, though some volcanic islands can sometimes appear quite suddenly

Answer:

As volcanoes erupt, they build up layers of lava that may eventually break the water's surface. When the tops of the volcanoes appear above the water, an island is formed.

Answer:

1) oxidation

2) Reduction

3) Oxidation

4) Reduction

5) Reduction

6) Reduction

7) Oxidation

8) Reduction

Explanation:

Oxidation is said to have taken place when there is a positive change in the oxidation number while reduction is said to have taken place when there is a decrease in the oxidation number.

The change from CH3CHO to CH3CH2OH represents on oxidation reaction.

The change from CH3OH to CH4 is a reduction because the oxidation number of carbon changes from +2 to -4.

The change from N2H4to N2 is an oxidation because the oxidation number of nitrogen increases from -2 to 0.

The gain in electrons is a reduction because the gain of electron leads to a decrease in oxidation number.

The change from NO- 2 to NH3 is a reduction because the oxidation number of nitrogen changes from +4 to -3.

The change from NAD+ to NADH is a reduction since NAD+ is the oxidized form of the enzyme while NADH is the reduced form of the enzyme.

The change from CH4 to Co2 is an oxidation because the oxidation number of carbon changes from -4 to + 4.

The change from Ag+ to Ag is a reduction because it involves the gain of one electron and a consequent decrease in oxidation number.

Answer: A. Raindrops act like a prism and separate the white light in sunlight.

Explanation:

The reason for the formation of rainbow is option A. Raindrop acts like a prism and separate the white lite into different colors.

Rainbow is an arc of colors from a white light ray which can be formed by the separation of component colors from white light by the combination of reflection, and refraction.

White light absorbs all colors and reflect all of them. That is why a white object is seen white the mix of all colors. When the white light passes through a raindrop, it gets refracted, the refracted light then reflects from the drop and undergo one more refraction and that make the component colors  in the form a bent or arc.

Therefore, raindrop is acting like a prism to separate the white light into its component colors.  Hence, option A is correct.

Answer: The ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20 is [tex]1s^22s^22p^63s^23p^5[/tex]

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neutrons and number of protons.

Mass number =  number of neutrons + number of protons

37 = 20 + number of protons

number of protons = 17

The atomic number is specific to an element, and the element with atomic number 17 is chlorine.

Electronic configuration represents the total number of electrons that a neutral element contains.

0.026 moles is the right answer.

We have that for the Question "How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K?" it can be said that  moles of xenon gas is

n=0.22moles

From the question we are told

How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K?

Generally the equation for the ideal gas is mathematically given as

[tex]n=\frac{Pv}{RT}\\\\n=\frac{0.64*8.5}{0.08206*300}[/tex]

n=0.22moles

Therefore

How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K is

n=0.22moles

Answer:

the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.

The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.

The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.

This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.

Therefore, the transfer energy is achieved when eating and feeding exists.
