Answer:
n = 1.7 moles
Explanation:
Given mass, m = 23.8 grams
Molar mass of Nitrogen = 14 g/mol
Let there is n number of moles. We know that,
No. of moles = given mass/ molar mass
So, there are 1.7 moles in 23.8 grams of Nitrogen.
It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
When, it donates electons.
as for example take
NaCl ( sodium chloride)
it's an ionic compund,
that means it is formed by donating or gaining electrons
Na is writen first than, it must be electropositive i.e it has donated electons which made it positive and the clorine gains electron so it's electronegative.
Na is positive because
as we know it's atomic number is 11 that means it has 11 protons and 11 electrons
now, when it donate electon it has, greater number of protons whose change is +ve so the atom becomes overall positively charged ion or cation.
and something same happens in clorine and because it gains one electron and the number of electrons increase in it by 1 whise charge is -ve so, the atom becomes negatively charged ion or anion which has a -1 charge.
Answer:
<em>1 mole is equal to 1 moles NaOH, or 39.99711 grams.</em>
Explanation:
<em>Hope this helps have a nice day :)</em>
The answer is 4.
Gases have low densities, because of the increased space between hight-energy particles.
