Calculate the number of molecules present in 0.5 mole of water​

Chemistry
1 answer:
Aleksandr-060686 [28]3 years ago
6 0

Explanation:

Mole = 0.5 = n/NA

n = no. of molecule

NA = avogadro number = 6.023x 10^23

so

N/NA = 0.5

N = 0.5 x 6.023 x 10^23

N = 3.0115 x 10^23

What is the atomic number of the as yet undiscovered element in which the 8s and 8p electron energy levels?
Andreyy89

The atomic number of the undiscovered element is 168

Element 118 will have just filled its 7p orbitals. therefore the predicted element to fill completely up to its 8 p orbital would have to filled a whole set of s, p, d, f and g orbitals

That's another 2 + 6 + 10 +14 + 18 = 50 electrons

To determine the total number of quantum numbers we have to find

Nml × Nms

we have Nml × Nms = ( 2 + 1 ) × 2

8s + 8P + 7d + 6f + 5g = 2 + 6 + 10 + 14 + 18 = 50

The element right below should be

Z = 118 + 50

   = 168

Hence the atomic number of the undiscovered element is 168

Two iron rods are placed horizontally, touching end-to-end. One end of one rod is heated. After some time, the other rod also fe
Genrish500 [490]

Answer:

Electrons conducted heat

Explanation:

Iron is a metallic compound. One property of metallic compounds are that they have many loose electrons.

Consider the two rods to be a singular rod, since they touch:

An uncountable number of electrons at one end of the rod are heated, so they gain kinetic energy. Those electrons then collide with other electrons, which energize those as well (although less), which is equal to adding heat. This is a pattern that will flow all the way through the rod.
