How many grams are in 2.5 moles of Carbon
Jet001 [13]
According to the periodic table, carbon's molar mass is 12.011 grams per mole (that's the small number under the element).  So, just multiply like this to get the answer:

(2.5\ mol\ C)(\frac{grams\ C}{12.011\ mol\ C})=0.20814\ g\ C

So, there are approximately 0.208 grams in 2.5 moles of carbon.

Three quantum numbers are derived from Schrodinger’s equation that describe the probability of finding an electron around a nucl
hodyreva [135]

Principle: Orbital size & main energy level

Angular: Orbital shape

Magnetic: Orbital orientation

Orbital size is Principle; main energy level is Principle; shape is Angular; orientation is Magnetic

Principle:

imagine a bullseye. each ring shows how far its from the nucleus

Angular:

0 looks like circle

1 looks like a bowtie

2 looks like a flower or 4 leaf clover

3 looks like multiple lobes

Principle Quantum Number: It describes the size of the orbital and the main energy level. It is represented by n. Where, n = 1,2,3,4....stands for K, L, M, N shell and so on..

Angular momentum Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of  will be -2, -1, 0, +1, +2.

If a reaction releases 675,000 Joules, how many kcal does it release?
Mamont248 [21]

Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Explanation:

According to the standard conversion,

1 Joule = 0.000239006 kcal

Therefore, 675,000 Joules will be converted into kcal as follows.

1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal

Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
