A solution of sodium acetate has a concentration of 0.1 M. Calculate the pH value when 0.0025 M of HCl has been added to the solution.
An unknown metal M reacts with sulfur to form a compound with the formula MS. If 4.37 g of M reacts with 2.51 g of S, what are the names of M and MS. (Type your answer using the format iron(II) sulfide for FeS.)
In a typical mass spectrum, a smaller signal is observed at a mass 1 amu higher than the molecular ion peak. Why? A) Due to small impurities in the sample
