Stoichiometry Knowledge check 1.Given the following balanced chemical equation, how many grams of HNO3 would be produced if 107.3 g of Sulfuric acid reacts with an excess amount of Barium nitrate? Ba(NO3)2 + H2SO4 --> BaSO4 + 2HNO3 _________HNO3

Ag(+aq) + Cl-(aq) AgCl(s) ∆H = +112 kJIf ions are colorless, and AgCl is whiteWill the reaction appear “colorless” or “white” if:a) Some of the AgCl (s) is removed?b) The pressure is decreased?c) The temperature is raised?

I need help solving thing and explanation on how you got this so I know what to do next time

Calculate the number of moles of magnesium nitride produced if 7 moles of magnesium were used as a reactant. Answer: _ mol Mg3N2

Stoichiometry Knowledge check 4.Given the balanced chemical equation below, determine the mass of CaCl2 produced if 4.9 g of Ca(OH)2 reacts with 18 g of HCl. Ca(OH)2 + 2HCl --> CaCl2 + 2HOH   g CaCl2 How many grams of excess reactant remains after the reaction occurs?   g   Blank 1:  Blank 2:

Following stoichiometry problem step by step on a sheet of paper or white board explaining each step in great detail. Where did you get each number? What is the final answer? Pay attention to sig figs also. Upload your recording.  C4H8(g) +  6 O2(g)  ⟶⟶4 CO2(g)  +  4 H2O(g) Using the reaction above, show and explain on video how many liters of carbon dioxide can be created if I start with 0.2495 grams of C4H8 gas at STP?

For the reaction: 4N2H4(g)+2N2O4(g)→6N2(g)+8H2O(l) the theoretical yield of H2O is15.7g. Suppose that the actual yield of H2O is 11.0g, what is the percent yield?
