A Compound
clean with luke warm water and a spoonfull of soap and let it air dry
deductive reasoning
If a test tube is clean and dry, then there should be nothing in it.
a non example of a streak is what it does not make a marking
Well it is going from a solid straight to a gas {example} Dry ice it does not melt it just goes poof in the air slowley
Dry air is not a solution but mixture of gases.
Clean dry air is composed of approximately 78% nitrogen by volume. Therefore, in 500 moles of clean dry air, the number of moles of nitrogen can be calculated as 0.78 x 500 moles, which equals 390 moles of nitrogen.
Nitrogen.
wash with cold water and soap and air dry
Throw them in the wash and air dry
Wash, dry clean, or air out.
clean with luke warm water and a spoonfull of soap and let it air dry
You can clean your air filter with an air hose. You can also clean your filter by submerging it in soapy water. Allow the air filter to completely dry before putting it back in.
The two most abundant gases in clean dry air are nitrogen, making up about 78%, and oxygen, making up about 21%.
you poo on it, and then it gets shiny and clean
Put it in the wash on what you would put. Silk on and air dry it
The most abundant compound in clean and dry air is nitrogen gas, which makes up about 78% of the atmosphere. Oxygen is the second most abundant compound in the atmosphere, comprising about 21%.
