Answer:
N³⁻ contain seven protons and ten electrons.
Explanation:
Nitrogen have seven protons and seven electrons. When it an atom lose or gain the electrons ions are formed.
Cation:
When an atom lose the electrons the formed is called cation.
e.g Na⁺ sodium lose one electron and form cation.
Anion:
when an atom gain the electrons the ions formed is called anion.
e.g N³⁻
Nitrogen consist of seven electrons and seven protons. when it gain electrons anions are formed. In given symbol nitrogen consist of 3- charge which means nitrogen gain three more electrons so total electrons will be ten.
Answer:
To get number of neutrons, you must have the mass number and atomic number of that atom.
atomic number is number of protons
<span>The boiling point of bromine (br2) is lower than iodine monochloride (icl) because icl molecules have a higher melting point. Also, the atoms of iodine monochloride have more electrons causing the intermolecular forces between iodine forces to be stronger. As the iodine forces are stronger, the boiling point will be higher.</span>
<u>Answer:</u> The pressure of NO and 
in the mixture is 0.58 atm and 0.024 atm respectively.
<u>Explanation:</u>
We are given:
Equilibrium partial pressure of 
= 0.29 atm
For the given chemical equation:
Initial: a
At eqllm: a-2x 2x x
Calculating for the value of 'x'
Equilibrium partial pressure of NO = 2x = 2(0.29) = 0.58 atm
Equilibrium partial pressure of = a - 2x = a - 2(0.29) = a - 0.58
The expression of 
for above equation follows:
We are given:
Putting values in above expression, we get:
Neglecting the value of a = 0.555 because it cannot be less than the equilibrium concentration.
So, 
Equilibrium partial pressure of = (a - 0.58) = (0.604 - 0.58) = 0.024 atm
Hence, the pressure of NO and in the mixture is 0.58 atm and 0.024 atm respectively.
A ecosystem is SUSTAINABLE if it can continue to function over long periods of time.
