A homologous series may be defined as a family of organic compounds having the same functional group, and the successive(adjacent) members of which differ by a CH
2
unit or 14 mass units.
Two consecutive members of homologous series of Aldehydes: CH
3
CHO and C
2
H
5
CHO
A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
Answer:
3 m/s
Explanation:
24 m/s over 8 seconds would be 24/8 making it be 3 m/s avg
Answer:
This reaction is an hydration of alkenes and the major product is 3-ethyl-2-heptanol
Explanation:
In this reaction in the first step water is the nuclophile and the alkene is the electrophile. Then, the carbanion is the nucleophile and attacks a proton from the water forming the respective alcohol. This carbanionic compound is a reaction intermediary. You can see the mechanism in the picture.
Is that carbanionic compound who explained the major product because the more substituted carbanion the most stable intermediary. Thus, the 3-ethyl-2-heptanol intermediary is the most stable and this product is the major one.
I hope it helps!
Answer:
![\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}=31.62](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bmagenta%5C%20phenolphthalein%5D%7D%7B%5Bcolorless%5C%20phenolphthalein%5D%7D%3D31.62)
Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:
Where Ka is the dissociation constant of the acid.
pKa of phenolphthalein = 9.40
pH = 10.9
So,
![\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}=31.62](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bmagenta%5C%20phenolphthalein%5D%7D%7B%5Bcolorless%5C%20phenolphthalein%5D%7D%3D31.62)
Answer:
180.845 mol
Explanation:
Molar mass of Ca: 40,078 g/mol
Molar mass of C: 12,0107 g/mol
Molar mass of O: 15,999 g/mol
Molar mass of CaCO3: (40,078+12,0107+3×15,999) 100,0857 g/mol
The number of moles= mass of bag in g ÷ molar mass of CaCO3
⇒ n= (18.1×1000)÷100,0857 = 180.845 mol
