Answer:

Uses of various electromagnetic waves depend on their relative energy.

Explanation:

The electromagnetic spectrum is the term used by scientists to describe the entire range of light that exists from radio waves to gamma rays. Electromagnetic waves is a wave of alternating electric and magnetic fields. The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves. The spectrum of waves is divided into sections based on wavelength. The shortest waves are gamma rays, which have wavelengths of 10^-6 microns or less. The longest waves are radio waves, which have wavelengths of many kilometers.

The application of various electromagnetic waves in science and technology depends on the energy of the wave. Electromagnetic waves that possess very high amount of energy are used in medical diagnosis, treatment of tumors, searching of baggage and detection of flaws in metal casting. Examples of such electromagnetic waves include gamma rays and xrays.

Some part of the electromagnetic spectrum possess energy enough to excite chemical bonds and produce spectra characteristic of certain functional groups in molecules. The ultraviolet and infrared rays fall into this category.

Some portion of the spectrum possesses very low energy and long wavelength and are mostly used for communication, mild medical diagnosis and resonance imaging/spectroscopy. Radio waves fall into this category.

Mrac [35]

Answer:

CuBr₂(aq) + Pb(CH₃COO)₂(aq) → Cu(CH₃COO)₂(aq) + PbBr₂ (s)↓

Explanation:

We identify the reactants:

CuBr₂ and Pb(CH₃COO)₂

The products will be: Cu(CH₃COO)₂ and PbBr₂

You may know these information:

Salts from acetate are soluble.

Bromide can make solid salts with these cations: Ag⁺, Pb²⁺, Hg₂²⁺, Cu⁺

PbBr₂ is formed, so this will be our precipitate

The equation is:

CuBr₂(aq) + Pb(CH₃COO)₂(aq) → Cu(CH₃COO)₂(aq) + PbBr₂ (s)↓

A student made a graph to show the chemical equilibrium position of a reaction.
pogonyaev

Answer:

Concentration, because the amounts of reactants and products remain constant after equilibrium is reached.

Explanation:

The rate of reaction refers to the amount of reactants converted or products formed per unit time.

As the reaction progresses, reactions are converted into products. This continues until equilibrium is attained in a closed system.

When equilibrium is attained, the rate of forward reaction is equal to the rate of reverse reaction, hence the concentration of reactants and products in the system remain fairly constant over time.

When deducing the rate of reaction, concentration of the specie of interest is plotted on the y-axis against time on the x-axis.

Without doing any calculations, list the elements in c2h4o2 in order of decreasing mass percent composition.
tia_tia [17]
In <span>c2h4o2 there are
2 atoms of carbon
4 atoms of hydrogen
2 atoms of oxygen

Hydrogen atomic masses is 1 which was very low so 4 of them would still be the lowest mass percent. Then we have carbon and oxygen which both have 2 atoms. Oxygen atomic mass is more than carbon atomic mass, so oxygen should contribute more mass percent composition. The sequence from higher mass percent composition should be:
1. Oxygen
2. Carbon
3. Hydrogen</span>
