what are the moles of, 1.87 g SiO2, 0.95 g NH4Cl, and 2.46g NaCl?
A mixture was found to contain 1.20 g of NH4Cl, 0.90 g of NaCl, and 1.20 g of SiO2. What is the percentage of Ammonium Chloride in this mixture?
A 1.507 g sample was found to contain 0.872 g SiO2, 0.206 g NH4Cl, 0.155 g NaCl, and the remainder being Fe. Calculate the percent composition of your mixture.
You analyzed 2.475 of a mixture of NaCl, SiO2 and CaCO3. You isolate .825g NaCl, .825g of CaCO3 and .580 g SiO2. You were told that the original mixture contained 35% NaCl, 45% CaCO3 and 20% SiO2. Calculate, compare, and offer an explanation for the differences in the composition of NaCl, CaCO3 and SiO2 you recovered. Explain.
Consider the following reaction: 2HI(g) =H2(g) +12(9) If 1.87 moles of HI, 0.333 moles of H2, and 0.277 moles of Iare at equilibrium in a 14.7L container at 888 K, the value of the equilibrium constant, Kp. is Submit Answer Retry Entire Group 9 more group attempts remaining
1. How many moles of NaCl (s) can be formed from 32 moles of Cl2 (g) reacting with an excess of Na (s)? Na (s) + Cl2 (g) -> NaCl (s) 2. How many moles of H2CO, can be formed from 2 moles of HCl reacting with an excess of Na2CO3? HCI + Na2CO3 -> NaCl + H2CO3
