Answer: Carbon dioxide made of carbon and oxygen.

This is because compounds are the combination of two atoms from different elements (carbon and oxygen). Hope this helps :)

If a non-cyclic alkane shows a molecular ion peak at m/z 3.80 × 102, what is the chemical formula?

soldier1979 [14.2K]

The General Equation of Alkane is as follow,

CnH₂n₊₂ ------- (1)
As m/z = 380
So,
CnH₂n₊₂ = 380
Or,
12n+ 1₂n₊₂ = 380

12n+ ₂n ₊ ₂ = 380

14n ₊ ₂ = 380

14n = 380 - 2

14n = 378

n = 378 / 14

n = 27
Now, putting value of n in eq. 1

C₂₇H₍₂₇ₓ₂₎₊₂

C₂₇H₅₆
Result:
n = C = 27

y = H = 56

What are the properties of an ionic bond?

Goryan [66]

Answer:

Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.
