Follow the given steps:
Balance the equations.
Calculate the molar mass of substances involved.
Use the mole ratios between substances involved to solve the problems.
Given the following reaction:
_Na2S2O3 + _AgBr __NaBr + __Na3[Ag(S2O3)2]
a. How many moles of Na2S2O3 are needed to react completely with 40.7 g of AgBr?
b. What is the mass of NaBr that will be produced from 40.7 g of AgBr?
2. From the reaction: _B2H6 + _O2 _HBO2 + _H2O
