The establishment, consolidation and cohesive phases constitute the progression stages in building a positive classroom climate. true or false?
when should I use 10 ^(2pH) in equilibrium concentration questions?
A student was tasked to perform gravimetric analysis of a soluble sulfate. His unknown sample weighed 0.7543 g. The sample underwent
precipitation using BaCl2 and was digested for overnight. The precipitate was then filtered off to obtain white crystalline precipitate that was collected in
an ash less filter paper. In performing constant weighing, he obtained a crucible mass that is 29.9442 g. After burning his samples inside the crucible,
the obtained mass was 30.3375 g. Compute for the mass (g) of BaSO4 from the experiment.
