Explanation:
The formula applied here is rydberg's equation (Bohr's equation.)
E = -Rh (1/(nf)^2 - 1/(ni)^2)
where Rh = Rydberg constant = 2.8*10^-18
1 mole = 6.02 * 10^23 particles
nf & ni stand for final & initial principal quantum numbers respectively.
your question lacks the principal quantum numbers.
Answer: 44,8 l. of CO2 and 72 g. of water will be produced
Explanation:
Answer:
the ander is B. 6 neurons
Answer: Option (d) is the correct answer.
Explanation:
It is known that water loving bonds are called hydrophilic bonds and water hating bonds are called hydrophobic bonds. Since, water is a polar solvent and it is only able to dissolve polar molecules and not non-polar molecules.
Lattice of water and hydrogen bonding are responsible for the various properties of water like cohesion, adhesion, heat of vaporization etc.
Thus, we can conclude that water lattice excludes non-polar substances.
Answer:
Water and acetone is best by separated through distillation
The correct answer would be option C Acetone and water.
Explanation:
When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.
The different liquids that are present in mixture are boiled and the vapours are condensed and the condensed portion is accumulated in another beaker.
