The chemical formula for strontium sulfide is SrS. A chemist determined by measurements that 0.0900 moles of strontium sulfide participate in a chemical reaction. Calculate the mass of strontium sulfide that participates. Be sure that the answer has the correct number of significant digits.

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

In which phase(s) do the molecules take the shape of the container?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
