AgNO3 + HCl + H2O?
1 AnswerChemistry5 years agoHow do you predict reactions when they are not single/double replacements?
How can you predict reactions that don't follow the "typical" reactions (like double replacement)?
Ex. Na2SO3 + 2HCl = 2NaCl + H2O + SO2
Why isn't it 2NaCl + H2SO3?
Any help is appreciated
