If I made no mistake in calculation, the given answer must be correct...(tried my best)
elements : carbon hydrogen oxygen Fluorine
composition [C] 24 3 16 57
M r 12 1 16 19
(divide C by Mr) 2 3 1 3
(Divide by smallest value) 2 3 1 3
(smallest value = 1...so all value remained constant)
Empirical formula : C2H3OF3
if molar mas = 100 g per mole, then
first step calculate Mr. of empirical formula: [= 100]
Them molecular formula = empirical formula
Answer:
The number for the element group is cited above the top element of each column. The element group values are integers running from 1 to 18. Examples: Hydrogen belongs to element group 1. Beryllium is the first element in group 2.Explanation:
Answer:
Allows for a quick "doubling of population because they skip pollination and fertilisation. There is less energy required for asexual reproduction. Large colonies can form that out complete the other organisms for nutrients and water. ... Sexual reproduction leads to genetic variation in new generations of offspring.
Explanation:
Answer:CH3â€"CH2â€"CHClâ€"CH3
Explanation:
This is due to Makownikov's rule which states that the negative part of the addendum adds to the carbon atom with the least numberbif hydrogen atoms. Another explanation is that, this product is formed from a secondary carbocation which makes it thermodynamically more stable. Compared to the minor product formed from a primary carbocation.
