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.
what are the moles of, 1.87 g SiO2, 0.95 g NH4Cl, and 2.46g NaCl?
A student did this experiment and found her mixture was 15.05% NH4CL, 19.95% NaCl and 75.10% sand. What's wrong with these numbers and what might have caused the problem?
A mixture of NaCl and NaBr has a mass of 2.04g and is found to contain 0.77g of Na. What is the mass of NaBr in the mixture?
A mixture of NaCl and NaBr has a mass of 2.06 g and is found to contain 0.77 g of Na. What is the mass of NaBr in the mixture? Express your answer using two significant figures.
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.
Ammonia and hydrogen chloride react to form solid ammonium chloride, NH4Cl(s): NH3 (g) + HCl (g) -> NH4Cl(s). Two 2.50 L flasks at 20.0°C are connected by a stopcock. One flask contains 5.80NH3(g) and the other contains 4.40 HCl(g). When the stopcock is opened, the gases react until one is completely consumed. A. Which gas will remain in the system after the reaction is complete? B. What will be the final pressure of the system after the reaction is complete?...

w ten species is the catalyst? 6. A mixture with [N:04) - 0.90 and [NO:] = 0.134 at 25°C is at equilibrium as follows: N:04(g) = 2 NOxg) What is the equilibrium constant, Ke, for the reaction? 7. Consider the reaction: C(s) + CO (g) = 2 CO(g), Ke=0.113 at 25°C An equilibrium mixture at 25°C was found to have a CO, concentration of 0.200 M. What is the CO concentration? 8. If Kc - 35 x 10 at 500...
Ammonia and hydrogen chloride react to form solid ammonium chloride: NH3(g) + HCl(g) ---> NH4Cl(s) Two 2.00-L flask at 25 degrees celcius are connected by a valve. One flask contains 5.00 g of NH3(g) and the other contains 5.00 g of HCl(g). When the valve is opened, the gases react until one is completly consumed. a) Which gas will remain in the system after the reaction is complete? b) What will be the final pressure of the systerm after the...
