Answer:
0.3808
Explanation:
number of moles,n=Conc.XVol.
hence 0.85X0.448
Answer: To be able to not forget what have they done when they want to re-do it.
to make it easier for the next person to re-do the experiment.
Explanation:
the description of the procedure ensures that when the experiment becomes of a success,specific steps are recorded for improvement of the experiment if maybe the experiment can be done at a short space of time.
I really hope that this helps. H-F because the difference in electronegativity is the greatest, about 1.9 on the Pauling scale. The term means which bond has the greatest polarity and is thus most similar to an ionic bond, which involves the transfer of an electron (in opposition to covalent bonds, which share electrons). It is H-F because out of all the atoms here bonded with H, ie hydrogen, F is the most electronegative which means it can pull the bonded electrons to itself more than can Cl, O, and N. <span>That means a stronger polarization of the electron cloud forming the bond with hydrogen and therefore a stronger ionic character.</span>
Answer:
magnesium chloride: MgCl2
zinc sulphide: ZnS
sodium sulphate: Na2SO4
calcium bicarbonate: Ca(HCO3)2
For ionic bond
The metal atom will lose electrons to form cations and the non metal atom will gain electron.egNaCl
