Answer:
A). half, higher
Explanation:
The Formal charge is elaborated as the 'allocated charge to a molecules' atom' on the basis of the assumption that the electrons present in the chemical bond are equally split among the atoms. It is estimated by 'halving the no. of bonding electrons that encircle the atom.
While Oxidation number is characterized as the 'hypothetical charge of an atom that is present within a molecule.' It is also defined as 'the actual number of lost or gained electrons or the rate at which the electrons are gained or lost by an atom to develop a chemical bond along with the other atom.' It is <u>calculated by allocating or sharing the electrons having the higher electronegativity belonging to a specific bond with the other</u>. Thus, <u>option A</u> is the correct answer.
Answer:
volume=0.4ml
Explanation:
use the equation
n=c×v. first make v become the subject of the formula by dividing c on both sides of the equation
v=n/c
v=0.100÷2.5×10^-2
v=4×10^-4
v=0.0004L
now convert 0.0004L to ml by multiplying 0.0004 with 1000 to get 0.4ml
therefore the volume in ml is 0.4ml
Answer: Mass is the amount of matter in a substance. Volume is the amount of space matter takes up. Matter has both physical and chemical properties.

Rays (or N-rays) were a hypothesized form of radiation, described by French physicistProsper-René Blondlot in 1903, and initially confirmed by others, but subsequently found to be illusory.
