Answer:
1. Ag+ precipitates. 2. Ca2+ precipitates. 3. Co2+ precipitates.
Explanation:
First AgBr is formed which is practically insoluble in water. CaBr2 and CoBr2 are soluble.
Then precipitates CaSO4. CoSO4 is soluble.
And then precipitates Co2(PO4)3 which is insoluble.
Answer:
electrons are located outside of the atoms nucleus
Answer:
0.3mL
Explanation:
Mass = 0.30mg
Concentration = 1.0 mg/mL
Volume = x
The relationship between the three parameters is given as;
Concentration = Mass / Volume
Making Volume our subject of interest we have;
Volume = Mass / Concentration
Substituting the values we have;
Volume = 0.30 mg / 1 mg/mL = 0.3mL

Answer:
1.67×10^-1
Explanation:
Use the formula n=m/R.M.M
Find the R.M.M. Formula of the compound is AgNO3.
So Ag mass is 108, N mass is 14, and O mass is 16.
So 108+14+(16×3)=170.
Than use formula n=28.39/170 giving 0.167. In scientific notation 1.67×10^-1.
