Answer: False
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Example: has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.
has molecular formula of
but
as the empirical formula.
Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation when when aqueous solutions of chromium(III) sulfate and calcium nitrate are combined is:
4 x in dL will be 4 x
Recall that:
Deci =
Centi =
Thus, 1 dl = 100 ml
This means that converting from dl to requires multiplying by
.
Applying this principle, 4 x in dL to
will be:
4 x x
= 4 x
Therefore, 4 x dl will be 4 x
