Answer:
Explanation:
Many elements have similar properties. This can be seen in how periodic table is arranged. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
For eg: Lithium, Sodium, and Potassium fall under group one in periodic table. These elements exhibit similar properties such as being extremely reactive.
The chemicals combination of the atoms is called a compound. The bond is formed between the atoms of each of the reacting elements thereby forming a new substance altogether. The compound will often exhibit different characteristics from the originating elements.
Answer:
c. Kay's rule
Explanation:
Kay's rule -
The rule is used to determine the pseudo reduced critical parameters of mixture , with the help of using the critical properties of the components of a given mixture .
The equation for Kay's rule is as follows ,
PV = Z RT
Where Z = The compressibility factor of the mixture .
Hence from the given options , the correct answer is Kay's rule .
Answer is: C. CH3CHOHCH3.
Balanced chemical reaction of hydration of propene:
CH₃CH=CH₂ + H₂O → CH₃CHOHCH₃.
A hydroxyl group (OH⁻) attaches to one carbon of the double bond and a proton (H⁺) adds to the other carbon of the double bond according to Markovnikov's rule (hydrogen gets attached to the carbon with more hydrogen substituents).
Product of this reaction is propan-2-ol (isopropyl alcohol).
