Leaves (and probably other things as well) that have fallen make the soil richer from decay.

A) Since both are carbons with the only difference in the number of neutrons,

They are called Isotopes

B) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,

Therefore Carbon-12 and Carbon-13 have the same number of protons

C) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,

Therefore Carbon-12 and Carbon-13 has different numbers of neutrons

D) Sorry i don't know any uses of Carbon-12 and Carbon-13, you might have to research to get it.

E or F) Sodium 23 has 12 neutrons and 11 electrons, because its mass number 23, atomic number is 11 and since protons and electrons count is same, the number of neutrons = mass number - atomic number = 23 - 11 = 12 neutrons

Happy to help :)

Draw the structures of the following compounds from their names: Pentane 3-methyl-hexane 2,4-dimethylpentane

Monica [59]

I am assuming that the compounds given are Pentane, 3-methyl-hexane, and 2, 4-dimethylpentane considering that the compounds were not separated by a comma.

_______________________________________________________

Pentane is in the form of a straight chain alkane. This is important as there are many isomers of Pentane, taking different shapes. By it's name it consists of 5 carbon atoms, and the number of hydrogen atoms should be 12, as the compound is nonpolar.

3-methylhexane is an alkane present in a hexane structure at position 3. There are thus 3 molecules at 3 ends of a hexane structure - H3C, CH3, and CH3

2,4-dimethylpentane is an alkane with respect to the formula [(H3C)2CH]2CH2.

With that information, refer to the three attachments below, for each compound given. They are in order -
