Which of the following sets of empirícal formula, molar mass, and molecular formula is correct?

skad [1K]

Answer:

The option C is correct.
CH4N, 90g, C3H12N3.

Explanation:

Option C:

The molecular formula is C3H12N3.

If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

Option A :

In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.

Option B:

In option B, molecular formual is not valid.
It should be as C6H16O2

Determine the element of lowest atomic number that contains a complete d subshell in the ground state. element symbol:

allsm [11]

The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .

Further Explanation:

atomic number:

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.

The elemenents of the intermittent table arranged by atomic mass:

atomic Mass Name substance element Number

1.0079 Hydrogen 1

4.0026 Helium 2

6.941 Lithium 3

9.0122 Beryllium 4

atomic number speak to:

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.

Meaning of subshell:

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.
