The chemical equation is:
2 Sr(NO3)2 + 2 Na2S = 4 NaNO3 + 2 SrS
To calculate the mass percentage of strontium in strontium sulfide, you need to know the molar mass of strontium sulfide (SrS), which is 119.63 g/mol. The molar mass of strontium (Sr) is 87.62 g/mol. To find the mass percentage, you would divide the molar mass of strontium by the molar mass of strontium sulfide, and then multiply by 100. This would give you the mass percentage of strontium in strontium sulfide, which is approximately 73.2%.
Most nitrate compounds are highly soluble in water, so adding strontium nitrate to water would create a large number of free ions in the water. These free ions could then act as charge carriers, making the water able to conduct current. Since adding strontium nitrate would make the water conductive, strontium nitrate is an electrolyte. Some other strontium salts, such as strontium sulfide, wouldn't dissolve significantly in water, so they wouldn't create the free ions necessary to conduct current.
Strontium sulfide (SrS) is not soluble in water and therefore does not readily form an aqueous solution.
The chemical name for CrS is chromium sulfide. It is composed of chromium and sulfur atoms in a 1:1 ratio.
The chemical equation for the reaction between aqueous strontium sulfide (SrS) and aqueous copper sulfate (CuSO4) is: SrS + CuSO4 → SrSO4 + CuS Strontium sulfate (SrSO4) and copper sulfide (CuS) are the products of this double displacement reaction.

The strontium sulfide has the chemical formula SrS.
When sodium sulfide and cadmium nitrate are mixed, a double displacement reaction occurs. The sodium from sodium sulfide switches places with the cadmium from cadmium nitrate to form sodium nitrate and cadmium sulfide. Cadmium sulfide is a yellow solid that precipitates out of the solution.
The strontium sulfide has the chemical formula SrS.
