Answer:
K2CO3 = K2O + CO2
Explanation:
In a chemical equation, the number of atoms on the left needs to be balanced with the number of atoms on the right, and there has to be the same number of the same *type* of atom on both sides as well.
On the left:
2 K
1 C
3 O
and on the right,
2 K
1 O
On the right, there are a few atoms missing, specifically, 1 C and 2 O.
The missing atoms then should be added to the side missing the atoms, preferably in a stable molecule. Luckily, CO2 contains exactly 1 C, and 2 O s, and is quite stable. So, a "CO2" has to be added on the left
<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11
<u>Explanation:</u>
Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.
This energy is calculated by using Einstein's equation, which is:

where,
E = Binding energy of the atom
= Mass defect = 0.0343g/mol =
(Conversion factor:
)
c = speed of light = 
Putting values in above equation, we get:

(Conversion factor:
)
Hence, the binding energy for lithium-6 nuclei is 3.09 E+11
Answer: Electrons
Explanation: The electrons are found outside the nucleus and orbit it.
This would be a homogenous mixture (either a colloid or a solution).
