Start with the process of elimination. Obviously, color is not a specific component to a wave, so we can cancel that out. While there are frequencies and measurable speeds of waves, those are not considered parts of the wave; nor is the wavelength or the base considered to be a part of the wave. The crest is the highest point of the wave, and is considered a part of the wave, as well as the trough, which is the the lowest point on the wave.

Solid silver chloride, AgCI(s), decomposes to its elements when exposed to sunlight Write a balanced equation for this reaction
Mrac [35]

Answer: The coefficient in front of AgCl when the equation is properly balanced is 2.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Decomposition of silver chloride is represented as:

2AgCl(s)\rightarrow 2Ag(s)+Cl_2(g)

Thus the coefficient in front of AgCl when the equation is properly balanced is 2.

the air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. How much pressure is this in pounds per square
Nutka1998 [239]

Answer:

7.5 pounds per square-inch

At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.

What describes the change in oxidation states of the following reaction? Cu2+ reduces to Cu, and Al oxidizes to AI3+. Cu2+ oxidi
Scilla [17]

The reaction is

Cu⁺²(aq) ---> Cu(s)  [reduction]

The species which undergoes reduction is able to oxidize other one thus will called as "oxidizing agent"

Thus Cu⁺² is an oxidizing agent

or Cu is a reducing agent

Al(s)  ---> Al⁺³(aq)

Aluminium is undergoing oxidation

Thus is able to reduced others and hence is a reducing agent

Al is a reducing agent

or Al⁺³ is an oxidizing agent

Answer: Cu is the reducing agent, and AI3+ is the oxidizing agent.
