They are considered to be highly reactive/ caustic - generally speaking a acid (<7pH) and a base (>7pH) combine together to make a relatively neutral salt (~7pH).
Diffusion is when materials move from areas of high concentration (high amount) to areas of low concentration (low population).Osmosis is the same as diffusion, but it's only when WATER moves from areas of high concentration to areas of low concentration. STAY IN SCHOOL JUNIORS!!(and pee-wees too. . .)
resistance means the te power to resist the heat or the electric current/ eg: tungsten which is used to make the filament of the bulb has a high melting point even when it burns on a high temperature so it has a high resistance, whereas in the wire of an electrical fuse has a low melting point as it burns at a high temperature...
You pour the substance over the gunpowder. If the wet gunpowder lighted, then the purity was considered high if it did not then the purity elwas considered low
Alkaline is considered to have a ph of 7.0 .. becoming more alkaline is 7 or <.
why do silicate materials have low electron density
Bread is not potentially hazardous because of it's low moisture content/
No, in most cases, the sense of smell is not a reliable means of identifying the presence of a hazardous materials.Many hazardous materials have no odor, and others are hazardous at concentrations that are too low to be smelled by most people.In addition there are many materials that have obnoxious odors but are not otherwise hazardous.
A limitation of using your senses to determine the presence of a hazardous material is that some hazardous materials are hazardous at concentrations too low for your senses to detect. In addition, some materials are very apparent to your senses at concentrations that are very small fractions of the concentration at which they become hazardous. If you are close enough to sense hazardous materials, you may have already endangered yourself.
5 is considered low and 20 is considered high.
Low hazardous products are classified as Low danger.
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration

The water activity in sprouts (mung bean, soy, alfalfa, etc) is high. They are a potentially hazardous food.
If you mean high to low concentration then the answer is passive transport, BUT if you mean low to high, then it's active transport
Low hazardous products are classified as less harmful type of pesticide.
