Answer:

Here ya go ;)

Small particles of dust and pollution in the air can contribute to (and sometimes even enhance) these colors, but the primary cause of a blue sky and orange/red sunsets or sunrises is scattering by the gas molecules that make up our atmosphere. ... In this way, clouds act as a screen on which nature's colors are painted.

At sunset the light from the sun grazes across the surface of the earth, passing through a long column or pathlength of atmosphere. During its passage through the atmosphere the blue components of the light are reduced in intensity, making the transmitted beam of sunlight more yellow or even red in color.

hope this helps ^^

Energy that is associated with the position or composition of an object is called a kinetic energy. b potential energy. c therma

VLD [36.1K]

<h2>The required "option is b) potential energy".</h2>

Explanation:

The energy which is associated with the motion of the object is called kinetic energy.
The energy which is associated with the amount of heat released is known as thermal energy.
The energy which is released during a chemical reaction is known as chemical energy.

Therefore, option (a), (c), and (d) are incorrect.

The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
Hence, the correct option is potential energy.

Difference between fluids and nonfluids

Mamont248 [21]

Answer:

All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.

Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.

Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.

notka56 [123]

Answer:

Protons, neutrons, and electrons

Explanation:

Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.

In an experiment, a student places a small piece of pure Mg(s) into a beaker containing 250.mL of 6.44MHCl(aq) . A reaction occu

solong [7]

Answer:

Mg(s) + 2H^+(aq) ----> Mg^2+(aq) + H2(g)

Explanation:

We must first write the molecular equation, then obtain the complete ionic equation and subsequently get the net ionic equation as shown below;

Molecular reaction equation;

Mg(s) + 2HCl(aq) ------> MgCl2(aq) + H2(g)

Complete ionic equation;

Mg(s) + 2H^+(aq) + 2Cl^-(aq) ----> Mg^2+(aq) + 2Cl^-(aq) + H2(g)

Net ionic equation;

Mg(s) + 2H^+(aq) ----> Mg^2+(aq) + H2(g)
