Pre-Lab Assignment: 1. Describe the procedure for vacuum filtration. (3 pts) MUST SHOW ALL WORK TO GET FULL CREDIT. USE SIGNIFICANT DIGITS. A student performed the following reaction using 2.50 mL of a 5.00 M aqueous solution of silver nitrate (AgNO3) and 1.80 mL of 3.00 M potassium chromate (K2CrO4) and obtained 1.567 g of silver chromate (Ag CrOs). Determine the limiting reactant. Calculate the theoretical yield and % yield of A&Cro. Use correct significant digits and show all work...

please answer 1 & 2 thank you 1. limiting Reactant - Mass to Mass: Perform two calculations to determine the limiting reactant and amount of product produced. Hydrogen cyanide, a highly toxic compound, is made by the following reaction: 2 CH4(g) + 2 NH3(g) + 3 O2(g) → 2 HCN(g) + 6 H2O(g) What is the limiting reagent with respect to HCN production if 45.4 g of O2 are added to 23.8 g of NH3? (assume CH4 is in excess)...
stoichiometry review: you measure 4.0 mL of 2.2 mol/L HCl, and you mix this with 30.5 mL of 3.25 mol.L NaOH. These undergo a neutralization reaction. which reactant is the limiting reactant? What is the theoretical yield of your product? show work for full credit
Use the data table to answer the questions please. Thank you
in advance! :)

What is the limiting reagent and theoretical yield? (please show work step by step with units) This is an aldol reaction with acetone, benzaldehyde, NaOH (5M in 25 mL solution = 5g), and an ethanol solvent. There is a 2:1 ratio of benzaldehyde and acetone. 3g of acetone which I calculated to be .05 moles . Since it was 2:1 I assumed that meant there needed to be 0.10 moles of benzaldehyde that I calculated to be 10.16 g.
