atoms because of the charge
Answer to the Question
C. Barium phosphate
Answer:
It would produce ethane (CH₃CH₃)
Explanation:
Ethylmagnesium bromide (CH₃CH₂MgBr) is a Grignard's reagent.
It is a highly reactive substance, and as any alkylmagnesium bromide
(R-CH₂MgBr) it reacts with water to produce an alkane (R-CH₃). R stands for any carbon structure bonded to that functional group.
By dividing the percentage composition with the molar mass of that element we will get the empirical formula. Then using that empirical formula and formula mass we can find the molecular formula.
<u>Explanation:</u>
The chemical properties of any substance are defined obviously by the different types and relative amounts of atoms constituting its primary entities (in case of covalent compounds the primary entities are molecules and ions in the event of ionic compounds).
A percent composition of any compound gives the mass percent of each element present in the compound; in addition to that frequently it is determined experimentally and utilized to derive an empirical formula of any compound. An empirical formula mass of any covalent compound could be comparable with the molar or molecular mass of a compound to acquire a molecular formula.
