Ionic bonds form between two elements that have a very large difference in electronegativity ie. a metal and a non-metal. The electronegative element will want an electron to make it stable whilst the less electronegative element wants to donate an electron to make it stable. Therefore the metallic element donates a electron to the non-metal and both become ions, which attract each other. Eg. Na becomes Na+ and Cl becomes Cl-, the opposite charges attract, forming the bond.
Answer:
Explanation:
A measurement is the action of measuring something, or some amount of stuff. So it is important to measure certain things right, distance, time, and accuracy are all great things to measure. By measuring these things or in other words, by taking these measurements we can better understand the world around us.
Answer:
0.54 moles of N2
Explanation:
First remember to find the volume in moles, 1 mole equals 22.4 liters.
So now use the dimensional analysis to show your work.
12 liters of N2 * 1 mol /22.4 liters of N2
Now calculate this. 12 * 1/22.4 or 12/ 22.4
12/22.4 = 0.535714286.
12 has two significant digits.
With that, The answer rounds to 0.54.
So that the final answer is 0.54 moles.
Hope it helped!
