did i do this correctly?
Instructions: For the following reactions, identify the precipitate and write its balancet net ionic equation:
H2SO4+BaCl2->HCl+BaSO4
answer:
2SO4+Ba->Ba(SO4)2
Close but no cigar.
You need to put the charges on SO4^-2 and Ba^+2.
You can see from the charges that the formula for barium sulfate is BaSO4 (in fact the problem lists it correctly--I wonder why you changed it? If you did it dileberatly; i.e., it was NOT an oversight, then we should talk about it.)
The balanced molecular equation is
H2SO4 + BaCl2 ==> BaSO4 + 2HCl
SO4= + Ba++ ==> BaSO4
oh sorry, i didn't mean to change those formulas. thanks for the help
To check if you did the problem correctly, we can break down the steps and compare them to the correct answer.
Step 1: Identify the reactants and products in the chemical equation:
H2SO4 + BaCl2 -> HCl + BaSO4
Reactants:
- H2SO4: sulfuric acid
- BaCl2: barium chloride
Products:
- HCl: hydrochloric acid
- BaSO4: barium sulfate
Step 2: Determine the solubility of the products:
- HCl: hydrochloric acid is a strong acid and is therefore soluble in water. It won't form a precipitate.
- BaSO4: barium sulfate is insoluble in water and will form a precipitate.
Step 3: Write the balanced molecular equation:
H2SO4 + BaCl2 -> HCl + BaSO4
The balanced molecular equation you provided is:
2SO4 + Ba -> Ba(SO4)2
Step 4: Write the net ionic equation:
The net ionic equation only includes the species that are directly involved in the reaction and excludes the spectator ions (ions that do not participate in the reaction). In this case, the spectator ions are H+ and Cl-.
The net ionic equation for the given reaction is:
Ba2+ + SO42- -> BaSO4
Overall, your answer for the balanced molecular equation is correct. However, the net ionic equation you provided is missing the charges on the ions. The correct net ionic equation is Ba2+ + SO42- -> BaSO4.
