A sample of hydrogen gas (H<sub>2</sub>) at 1.00 atm and 273 K has a volume of 225 mL. How many moles of hydrogen gas are there?
As we know that PV= nRT for an ideal gas. Now n=PV/RTP = 1.00 atm, V= 0.225 L, R = 0.082 L. atm. K-1. mol-1 , T= 273 Ktherefore n=(1x...

Balance the following equation by the electron-balancing method. Name oxidizing and reducing agents: NH<sub>3 </sub>+ O<sub>2</sub><sup> </sup>= N<sub>2</sub><sup> </sup>+ H<sub>2</sub>O
4NH3 + 3O2 = 2N2 + 6H2O4 N-III - 12 e- → 4 N0 (oxidation)6 O0 + 12 e- → 6 O-II (reduction)

Balance the following reactions of combustion
a) C2H4 (g) + O2 yields CO2(g) +H20(g) + Energy
The energy is throwing me off from doing a normal balancing equation. Can you help me with this
C2H4(g) + 3 O2 → 2 CO2(g) + 2 H20(g) + Energy “Energy” means that the reaction is exothermic and the heat (energy) is released. There is no need to...
