Radio and TV waves can be sent and received using many different types of electromagnetic waves. Waves with longer wavelengths can pass through obstacles with greater ease. They can also reflect off the ionosphere if the weather conditions are right. This allows waves with lower frequency to travel much greater distances. Below is a diagram of the electromagnetic spectrum

which type of wave would most likely travel the greatest distance ?

• FM radio waves
• AM radio waves
• Gamma waves
• TV waves

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal.b. he is determining chemical properties that are sufficient to identify the metal.c. he is determining physical properties that are insufficient to identify the metal.d. he is determining chemical properties that are insufficient to identify the metal.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
