The density of carbon in the form of diamond is 3.51 g/cm^3. if you have a small diamond with a volume of 0.0270 cm3 what is its

lora16 [44]

Hey there!:

density = 3.51 g/cm³

Volume = 0.0270 cm³

Therefore:

D = m / V

3.51 = m / 0.0270

m = 3.51 * 0.0270

m = 0.09477 g

How many electrons will a metal generally have in its outer energy level?

Zarrin [17]

Answer:

Metals have one or two electrons in their outermost shell

C. 1-2

Explanation:

Metals have low ionisation energy because they easily looses the outermost electrons

They have only one- two electrons in the outer most shell.

They loose these electron to form charged species called cation.

The combining of atoms is known as nuclear fusion. true false

dimulka [17.4K]

True, nuclear fusion is a reaction in which multiple atoms come in contact to form new atom and subatomic particles. in a nuclear fusion, some of the mass is lost which defies the law of conservation of mass, but according to scientist the lost in mass is manifested in the production of huge amount of energy,

I need help with organic chemistry!!!

Answer:

CHO2- ion

Explanation:

We have the lewis structure of a formate-ion here

This is CHO2-.

The carbon atom is the central atom in the structure. It's the least electronegative atom (C). Carbon has 4 valence electrons. Oxygen has 6 valence electrons.

The carbon will bind with 1 hydrogen atom, this will form 1 single bond, because hydrogen has 1 valence electron.

The carbon will bind with oxygen via a double bond.

Since carbon has only 4 valence electrons, it can only form 1 bond with the other oxygen atom.

There will formed 1 double bond between C and O and 1 single bond between C and O resulting in a negative charged O-atom.

This means there are two resonance structures. for the CHO2- ion
