Answer:
Explanation:
binary compounds means Metal + non metal
example : Kcl - potassium chloride
k is metal and cl is non metal
and in the end you have to use ide
6.17749 would be the mass
A mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. Mole ratios are used as conversion factors between products and reactants in many chemistry problems. Ratios are written like- #:#
Answer:
6 N
Explanation:
Per Archimedes' Principle, the buoyant force on an object is equal to the weight of the fluid displaced.
If the buoyant force is 6 N, the weight of the water displaced is 6 N.
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.
