From the a balance equation 2C6H6(1) + 1502(G) ---------12CO2(G)g) + 6H2O(1) How much CO2(in L) is produced from the conbustion of 189.0 g of C6H6 at STP

The air bags in cars inflate through the explosive decomposition of a solid to produce a gas. The simplified version of the reaction that takes place  in most air bags is shown. 2NaN3(s) -> 2Na(s) + 3N2(g) (a) If a typical air bag has a volume of 67.0 L when inflated, how much NaN3 (in grams) is required to inflate an air bag at STP? (b) Would you want to rely on an air bag that contained only 40.0 g NaN3? Explain.

A student experimentally determines the gas law constant, R, by reacting a small piece of magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.

[6] Magnesium carbonate reacts with hydrochloric acid to form the products shown below. If 45.0 g of MgCO; reacted with 50 ml of 0.1000M HCl what volume of CO2 would be produced at STP. MgCO3(s) + 2HCI (aq) → MgCl2(aq) + H2O(1) + CO2(g)

11.) According the following chemical equation. (not balanced) + NH3 (g) O2 (e) => C3N¿H3 (g) + H2O C,H6 () + O2® => C,N;H3 9 + H,0 () (8) At constant pressure of 2.0 atm and a constant temperature of 298K, 0.50 L of C,Ho , 0.8 L of Oz are mixed. How many liters of water vapor will be formed? If the water condensed into a liquid, how many liters of liquid H2Os would be formed?
