Answer:
C₅H₁₀O₅
Explanation:
Let's consider a compound with the empirical formula CH₂O. In order to determine the molecular formula, we have to calculate "n", so that
n = molar mass of the molecular formula / molar mass of the empirical formula
The molar mass of the molecular formula is 150 g/mol.
The molar mass of the empirical formula is 12 + 2 × 1 + 16 = 30 g/mol
n = (150 g/mol) / (30 g/mol) = 5
Then, we multiply the empirical formula by 5.
CH₂O × 5 = C₅H₁₀O₅
I would say B.HS(aq)+NiSO4(aq)
You need to be able to draw dot-and-cross diagrams to show the ions in some common ionic compounds.
Speed = Distance / Time
s = 10 / 2
s = 5 Km/h
In short, Your Answer would be 5 Km/h
Hope this helps!
The substance is a liquid. Think about water :)
