Answer:
F
Explanation:
because F had the bigger affinity than cl
The electrical conductivity of a conductor increases with increasing temperature
An electrical current flows through a conductor because it provides little to no resistance to the movement of electrons. Typically, good electrical conductors include metals, metal alloys, electrolytes, even some nonmetals like graphite and liquids like water.
Metals, aqueous salt solutions (ionic chemicals dissolved in water), graphite, and the human body are a few examples of conductors.
A conductor makes it simple for current to flow through it. Insulators prevent electricity from passing through them. On the surface of conductors, there is an electric charge. In an insulator, there are no electric charges. Keeping conductors in a magnetic field prevents them from storing energy.

Answer : The structure are shown below and the number of stereoisomers are possible in 3,5-dimethylnonane and 3,7-dimethyle-5-ethyldecane are 4 and 8 respectively.
Explanation :
Chiral carbon : It is carbon which is attached to the different types of atoms or molecules.
The number of stereoisomers possible for a compound is related to the number of chiral centers (n) present in it as,
where,
'n' is the number of chiral carbon present in the compound.
The number of chiral carbon present in 3,5-dimethylnonane is, 2 that means n = 2 (carbon-3 and carbon-5)
The number of stereoisomers are possible in 3,5-dimethylnonane is, 4
The number of chiral carbon present in 3,7-dimethyle-5-ethyldecane is, 3 that means n = 3 (carbon-3, carbon-5 and carbon-7)
The number of stereoisomers are possible in 3,7-dimethyle-5-ethyldecane is, 8
Answer:
C. Sold solution
Explanation:
Using method of elimination;
A. Pure substance.
Bronze is not a Pure substance because the proportions of copper and tin are not the same in all bronze. This option is wrong.
B. Colloidal Suspension
This option is wrong. Colloidal suspension involves one substance dispersed in another.
C. Sold solution
The bronze bell is an alloy. This definition suitable represents it. It is a solid solution containing copper and tin. This is the correct option.
D. Heterogeneous Mixture
Bronze is a mixture, however it is homogeneous and not heterogeneous. his is because one can not distinguish the copper from the tin in the mixture.
