Determine the volume of O2 (at STP) formed when 50.0 g of KCIO3 decomposes according to the following reaction. The molar mass for KCIO3 is 122.55 g/mol. 2 KClO3(s)-2 KCl(s) + 302(g) 8.22 L 14.6 L 13.7 L 12.3 L 9.14 L

In 2014, the World Anti-Doping Agency announced that Xenon gas would be added to the list of banned substances for athletes.    Apparently since 2004, Russian athletes had been inhaling xenon while training, with the physiological effect being to boost the capacity of blood to carry oxygen needs for aerobically demanding sports.    If an athlete inhaled an average of 1.75 x 10-4 moles of Xe per breath while sleeping, with an average rate of 13.0 breaths per minute for 8.50 hours how many total GRAMS of Xe(g) were inhaled while sleeping? please show all calculations

Use the chemical equation below to determine how many moles of ammonia will be produced from 4 moles of nitrogen gas. Assume that there is enough H2 for all of the N2 to be converted to NH3. N2 + 3H2 ---> 2NH3

Given that 4 NH3 + 5 O2  →  4 NO + 6 H2O,when 4.50 mol of H2O are formed, the amountof NO formed isA) 3.00 mol B) 6.75 molC) 1.50 mol D) 4.50 mol

Data Table 2: Alum Data Object Mass (g) Aluminum 2.38 g Cup (Empty) Aluminum Cup + 2.0 grams of Alum Aluminum Cup + Alum After 1st Heating Aluminum Cup + Alum After 2nd Heating Mass of Released 4.38 g 3.48 g 3.48 g 0.900 g

For the reaction shown, how many grams of Hg can be produced by the reaction of 18.0 g of HgO? Report 3 sig figs and don't put in units, just enter a number.                                                         2HgO(s) -->  2Hg(l) + O2(g)
