Answer : The hybridization of the positively charged carbon is .
Explanation : Formula used for Hybridization
Z=1/2{number of valence electrons of central atom + number of monovalent atom attached to it + negative charge - positive charge}
where, Z = Hybridization
Now for the compound
Number of valence electrons of central atom (C) = 4
Number of monovalent atom attached = 3
Number of negative charge = 0
Number of positive charge = 1
Now putting all the values in Z,
Z =
= 3
The corresponding Hybridization is i.e Trigonal planar .
Answer:
A) Separating funnel method
B) Simple Distillation
C) Evaporation
D) Sublimation
E) It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.
Explanation:
A)
B) Kerosene and petrol are both miscible liquids and the difference in their boiling point temperature is not more than 25°C. Thus, we make use of Simple distillation.
C) Can be separated by evaporation where the water is boiled and it evaporates and leaves the salt behind
D) To separate camphor from salt, we use sublimation so the camphor can change directly from solid to the gas state without passing through the liquid state.
E) Chromatography is used to separate components of a mixture.
It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.

Answer:
8.1m/s2
Explanation:
The following were obtained from the question:
V = 24.3m/s
t = 3secs
a =?
a = V / t
a = 24.3 / 3
a = 8.1m/s2
