Experiments in a Midwest greenhouse showed that vibrating the flower clusters with a 110-volt vibrator every day versus every other day between the hours of 10 ...

The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. A common request on this site is to convert grams to moles. To complete this ...

Manganese (CAS registry number ) makes up about 0.10% of the earth's crust and is the 12th most abundant element. It can exist in oxidation states from -3 to +7, the most common being +4 in the chemical form of manganese dioxide (Keen and Leach 1988). The oxides and peroxides are
