What type of bond is phosphorus sulfide?
Phosphine sulfides are formed from the reaction of organic phosphines with sulfur, in which the sulfur atom is linked to the phosphorus by a bond that has both covalent and ionic properties.
How do you write diphosphorus trioxide?
The formula for diphosphorus trioxide is P2 O3. The ''di'' in diphosphorus means two phosphorus atoms are present.
What is an empirical formula and how is it calculated?
In summary, empirical formulas are derived from experimentally measured element masses by: Deriving the number of moles of each element from its mass. Dividing each element's molar amount by the smallest molar amount to yield subscripts for a tentative empirical formula.
How do you find the empirical formula Wikihow?
To find the empirical formula of a compound, start by multiplying the percentage composition of each element by its atomic mass. For example, if a compound is 40.92 percent carbon, multiply 40.92 by 12, its atomic mass, to get 3.4.
