Use the balanced equation below to answer the following questions.

2Al(NO3)3 + 3Na2CO3 Al2(CO3)3(s) + 6NaNO3

- What is the ratio of moles of Al(NO3)3 to moles Na2CO3? (1 point)
- If 852.04 g Al(NO3)3 reacted with the 741.93 g Na2CO3, which would be the limiting reagent? Show your work.
- Use the limiting reagent to determine how many grams of Al2(CO3)3 should precipitate out in the reaction.
- If only 341.63 g of Al2(CO3)3 precipitate were actually collected from the reaction, what would the percent yield be?

I have an idea you want to check your answer. Rather than me do all of that typing to answer four LONG questions, tell me what you don't understand or if you want me to check you answers show your answers and I'll do that.
