Answer:
a and b.
Explanation:
I am assuming you mean LICl and NaCl.
a and b are soluble in water.
AgCl is insoluble - If you add sliver nitrate solution (Ag NO3 ) to NaCl solution a white precipitate of AGCl is formed.
Answer:
the answer is O²- hopefully
Answer: B. 448.0 moles
Explanation:
The balanced chemical equation is :
According to stoichiometry :
3 moles of produce = 1 mole of
Thus 48.00 moles of will produce = of
Mass of
Thus 448.0 g of will be produced from 48.00 moles of NaOH.
The equation for calculating a mass is as follows:
m=n×M
Molar mass (M) we can determine from Ar that can read in a periodical table, and a number of moles we can calculate from the available date for N:
n(H2SO4)=N/NA
n(H2SO4)= 1.7×10²³ / 6 × 10²³
n(H2SO4)= 0.3 mole
Now we can calculate a mass of H2SO4:
m(H2SO4) = n×M = 0.3 × 98 = 27.8 g
