Deforestation is the mass cutting of trees. Much of our oxygen comes from trees so if we cut down the trees then their will be more carbon dioxide in the air instead of the needed amount of oxygen.
Explanation:
-Salt is a white cubic crystals. ...
-It is odorless but has strong salty taste.
-Solubility in water is different at different temperatures.
-Hygroscopic(ability of a substance to attract and hold water molecules from the surroundings).
-Melting point of salt is 800.8 degree Celsius
Answer:
1) It is the number of particles in one mole of substance. It is an arbitrary definition to denote an amount of substance, not by its weight but by its number of molecules. Why? because that is convenient when doing certain calculations involving molecule formulas.
2) 1 mole of substance contains exactly as many particles as there are atoms in 12 grams of carbon-12.
3) The unified atomic mass unit is 1/12 of the mass of 1 carbon-12 atom.
So you see all three concepts are linked together.
Answer:
The air molecules are closer together in the upper stratosphere.
Explanation:
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.
