Option A is correct answer.
According to octet rule, atoms have tendency to lose, gain and share electrons to complete its octet i.e. eight valence electrons are surrounded to the atom.
Since, sulphur contains six valence electrons and two chlorine atoms are present in the reaction having seven valence electrons. Thus, to complete their octet, chlorine shares a pair of electrons with the sulphur atom.
A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. However, some definitions specify that the particles must be dispersed in a liquid, and others extend the definition to include substances like aerosols and gels.
The types of colloids includes sol, emulsion, foam, and aerosol.
- Sol is a colloidal suspension with solid particles in a liquid.
- Emulsion is between two liquids.
- Foam is formed when many gas particles are trapped in a liquid or solid.
- Aerosol contains small particles of liquid or solid dispersed in a gas.
Answer: B. (A 25 kg ball)
Explanation:
Since , and velocity is the same for all four balls, the ball with the greatest mass will have the greatest kinetic energy (since mass and KE are directly related). Below shows these calculations:
A. m = 5
B. m = 25
C. m = 10
D. m = 1
Answer:
E) HBr
Explanation:
Because Bromine (Br) isn't part of the original formula for Apirin. (I answered this based on the assumption that the letter "A" in option C was a typo of sorts, since there is no element with a chemical symbol of just "A" that I am aware of. If this is incorrect, then I apologize.)
