NaBr + Ca(NO3)2 ==> is mixed in aqueous solution, nothing will precipitate out.
All salts of sodium and all nitrates are soluble. It is possible a little calcium bromide may ppt out.
NaBr+CaNO3--- NaNO3+CaBr
Sodium bromide (NaBr) and Silver nitrate is AgNO3 When mixed in aqueous solution pale yellow(cream) coloured silver bromide will precipitate down . NaBr(aq) + AgNO3(aq) = AgBr(s) + NaNO3(aq) NB THis is the classic test for halogens. AgF remains in solution AgCl white ppt AgBr pale yellow ppt AgI yellow ppt.
Sodium hydroxide Sodium chloride Calcium nitrate Calcium chloride
Silver bromide is insoluble in water and don't react with sodium nitrate.
Yellow Precipitate of Silver Bromide
The molecular mass of sodium nitrate is 84,9947.

lead nitrate + potassium bromide --> lead bromide + potassium nitrate
It is lead bromide and potassium nitrate
Sodium hydroxide Sodium chloride Calcium nitrate Calcium chloride
The relative molecular mass of Ca(NO3)2, also known as calcium nitrate, can be calculated by adding the atomic masses of calcium (Ca), nitrogen (N), and three oxygen (O) atoms. The atomic masses are 40.08 g/mol for calcium, 14.01 g/mol for nitrogen, and 16.00 g/mol for oxygen. When you add these values together, the relative molecular mass of Ca(NO3)2 is 164.08 g/mol.
Silver bromide is insoluble in water and don't react with sodium nitrate.

off the top of my head = 102Let's break this down. Very easy- first, take the #atoms of each element, 1 calcium,2 nitrogen, 6 oxygen. You can pull these straight off of the chemical formula. Now, multiply by molar mass- on the periodic table. (calcium) 1*40.078=40.078, (Nitrogen) 2*14.0067=28.0134, (Oxygen) 6*16=96. Now, add 'em up. 40.078+28.0134+96=164.0914 (Grams/mole)nothing to it.
