Its overall charge is zero because it has 2 electrons 2 protons and 2 neutrons also it is zerovalent in nature as it is an inert gas
Answer:
A new element
Explanation:
As you add mopre and more protons and electrons and neutrons it keeps on crating new.
Answer:
Sl reproduction occurs when living organisms combine genetic information from two different types.
Explanation:
In this case, the hydrogen atoms are present in the (NH3)2 part of the molecule. The sign (NH3)2 mean that there are two NH3 molecules in their compound. That means the total atom of hydrogen would be: 3*2 = 6 atom for every compound molecule
Since there is 0.7 mole of compound, then the hydrogen atom would be:
0.7 mole * 6= 4.2 moles
Answer:
126g
Explanation:
Data obtained from the question include:
Mole of Fe = 2.5moles
Molar Mass of Fe = 56g/mol
Mass of Fe =?
Number of mole = Mass/Molar Mass
Mass = number of mole x molar Mass
Mass of Fe = 2.25 x 56
Mass of Fe = 126g
Therefore, the mass in 2.25mol of Fe is 126g
