Answer:
each of the above (A, B, and C) occurs
Explanation:
When an ionic compound dissolves in the water, the following happens :
-- the solvent solute attractive forces tries to overcome the solute solute attractions.
-- the water dipoles' negative end attracts the positive ions
-- the water dipoles' positive end attracts the negative ions
For example,
NaCl which is an ionic compound and also a strong electrolyte, it dissociates into water on the hydrated Na cations as well as Cl anions.
In water, the oxygen has negative charge and thus attracts the positive ions of the sodium, whereas the hydrogen is of positive and it attract the ions of chlorine which is negative.
2Al+3Cl2==>2AlCl3
(4mol Al)(2 mol AlCl3/2 mol Al)=4 mole AlCl3
Answer: The initial partial pressures of 
and 
is 139.4 torr.
Explanation:
The equilibrium reaction is
initially conc. p p 0
At eqm. p-2x p-x 2x
Given: 
The expression for equilibrium constant is :
= 2x =115 torr
= (p-2x) = p-115 torr
= (p-x)= p-57.5 torr
Now put all the given values in this expression, we get
Therefore, the initial partial pressures of and is 139.4 torr.
dude im so stress with school
i quit schoool
lol
M(S)=1 g
m(O)=1.5 g
M(S)=32 g/mol
M(O)=16 g/mol
n(S)=m(S)/M(S)
n(O)=m(O)/M(O)
n(S)=1/32=0.03125 mol
n(O)=1.5/16=0.09375 mol
S : O = 0.03125 : 0.09375 = 1 : 3
SO₃ - is the empirical formula
