The number of solid precipitate that will be formed is 37.08 g
calculation
write the equation for reaction
=Hg(NO3)2 +Na2SO4 = HgSO4(s) +2NaNO3(aq)
find the moles of each reactant
moles ofHg(NO3)2=126.27/324.6= 0.389 moles
moles of Na2SO4=17.796/142=0.125 moles
NaSO4 is the limiting reagent and by use of mole ratio of NaSO4:HgSO4 which is 1:1 therefore the moles of H2SO4 is also= 0.125 moles
mass HgSO4=moles x molar mass
=0.125 x296.65= 37.08g
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
Please link those observations so we can answer your question. have a good day <3
Answer:
By the Pauling rule, of EN
Explanation:
EN means electronegativity, the ability of atoms to attract electrons.
In the periodic table each atom, has a value of EN.
When there are two atoms bonded, you must substract the EN (the high - the low) → ΔEN
It depends on the ΔEN, that you can define a bond as ionic, covalent or metallic.
Ionic ΔEN → > 1.7
Covalent polar 0.4 < ΔEN > 1.7
Covalent non polar 0.4 < ΔEN
Two metals have always a metallic bond
