Answer: After losing the presidential reelection, Carter returned to Georgia and founded.
A. not C.
SLOW
Explanation:
Answer:
Evaporation is the method of separating a solid (solute) from a homogeneous solution.
in this method, the solution is heated until the solvent gets evaporated in the form of vapor and the solute is left behind as residue.
Answer:
Reactant : A combustion of hydrocarbon.
Explanation:
It is known that when hydrocarbons are involved in combustion, they produce carbon dioxide and water.
CxHy + (x+y/4)O2 ===> xCO2 + y/2H2O
Answer:
The transition which is associated with the greatest energy change is from n=1 to n=3.
Explanation:
where,
= energy of orbit
n = number of orbit
Z = atomic number
Energy of n = 1 in an hydrogen like atom:
Energy of n = 2 in an hydrogen like atom:
Energy of n = 3 in an hydrogen like atom:
Energy of n = 5 in an hydrogen like atom:
1) Energy change transition from n = 1 to n = 3 occurs .
Let energy change be E.
(absorption)
2) Energy change transition from n = 2 to n = 1 occurs .
Let energy change be E.
(emission)
3) Energy change transition from n = 3 to n = 2 occurs .
Let energy change be E.
(emission)
4) Energy change transition from n = 3 to n = 5 occurs .
Let energy change be E.
(absorption)
Highest magnitude of energy corresponds to the greatest energy change.So,the transition which is associated with the greatest energy change is from n=1 to n=3.
