In what order are redox reactions balanced? A. Atoms, O and H, then charge
B. Atoms, charge, then O and H
C. Charge, O and H, the atoms
D. O and H, charge, then atoms

Consider this initial-rate data at a certain temperature for the reaction described by

Asample of hydrated tin (ii) chloride (sncl2) has a mass of 4.90 g. when it is dehydrated, it has a mass of 4.10 g. which is the correct chemical formula for the hydrate? sncl2•2h2o          sncl2•4h2o          sncl2•6h2o

Suppose that some of the compound spilled out of the crucible after it was heated. would that cause the percent by mass of water in the compound determined by the experiment to be too low, too high, or unchanged? briefly explain your answer.
