I would say that descriptive investigations aren't repeatable because it means that you are only describing something - you ask certain question about something, but do not form a hypothesis at that point yet. So it would be a waste of time to simply ask the same questions over and over again with no hypothesis to prove, which is why these types of investigations cannot be repeated.
Radio waves.
From lowest to highest it is radio wave, microwave, infrared, visible light, ultraviolet, x ray, and then gamma.

Explanation:
How do I describe an ion?
<h2>an ion is an atom that has had electrons added or taken away from it.</h2><h2>they do this in order to obtain a stable electronic configuration like their closest noble gas..see Periodic Table column 18 which is also column VIIIA</h2><h2>If they gain electrons, they are negative and are called</h2><h2>ANIONS</h2><h2>if they lose electrons they are positive and are called</h2><h2>CATIONS </h2><h2 />
<span>0.570 M (note the capital M, this is molarity. Using m denotes molality.
Molarity is represented by moles of solute over the liters of solution. In this problem we are given the mass of the solute and volume of solution. The calculations is follows:
(15.7 g CaCO3/275 mL of solution) x (1 mole CaCO3/ 100.0869 g of CaCO3) x (1000 mL of solution/ 1 L of solution) = 0.570 M CaCo3.</span>
Answer:
HCO3- + BrO- → HBrO + CO32-
