Using only the elements Ca, Cl, Si, give formulas for the
following: (a) an ionic compound. (b) a molecular compound with
polar covalent bonds that obeys the octect rule and has no formal
charge. For part b I drew the lewis structure Cl(double
bond)-Ca-(double bond)Cl with two lone pair on each chloride, is
that correct? Please explain. Thank you.
How would you explain fluid and electrolyte imbalances with Na+,
K+, Mag+, Cl-, Ca+, P? And what would the signs and symptoms be if
a person were to be hypo or hyper? And what would be the nursing
interventions? (Not sure if you know, but I thought I would ask
just in case.)
Thank you
Calculate the empirical forumla of your compound. Set the
formula in the form Ni(Cl)x(NH3)y where x and y are determined from
their titration results.
From my titration results:
% mass of Ni+2= 25.8% (0.192mmol)
% mass of Cl- = 26.8% (0.315mmol)
% mass of NH3 = 45.4% (1.12mmol)
1-
why Pb2+ form a ppt with Cl- and if the ppt placed in hot water it
would dissolve?
2- why when NH3(aq) add to the Al3+ it would form solid then
if more NH3(aq) been add it would form complex ion?
3- why when NH3(aq) add to Mn2+ it would form solid even when
extra NH3(aq) add it didn’t dissolve but it would dissolve with
HNO3(aq)?
4- why Ni2+ didn’t form a ppt with H2S while Cu2+ form a...

Hexachlorobenzene, C 6 Cl 6 , is a solid compound that is
somewhat volatile but not very soluble in water; water is not
soluble in C 6 Cl 6 . Solid C 6 Cl 6 and liquid water are allowed
to
reach equilibrium at 20°C to form a solid phase, an aqueous
phase, and a gaseous phase. The vapor pressure of pure solid
C 6 Cl 6 is 1.45 mPa at 20°C and 8.85 mPa at 40°C.
