Question

b. How many liters of oxygen gas must react with 0.800kg of Fesmo" atm? CHEAP 01 8. When ammonia gas, NH, reacts with oxyoen, gaseous nitric Oxide (NO) and water vapor are collected. How many liters of NO can be made from 12L of oxygen and 10.0 of ammonia at constant pressure and temperature? 9. If a 1.0L container is filled with 1.00g of hydrogen gas and another 1.00L container is filled with 1.00g of nitrogen gas. Both containers are at room temperature, which container has the a) higher pressure b) contains more moles c) contains more molecules d) has greater kinetic energy e) has molecules that move with more speed (1) 8.40atm; (2) 1.76g: (3) 15.7L:(4) 9.67L:(5) 7.28x10 molecules: (60) 180L: (h) 16.2:16) 10410 molecules: (a) 175L: () 03:) 9.6L

Answer 1

Fes to ) Fe of tsa balance 2fes + 7 o reag + 25ą yres + 70 2 0 + 450 to calculate are moles redeat moles rest gal mass molar mass = 0.6ookg x 10 9 1 kg $7.919/mo z 6.82 moles. from reaction tx moles of res reacts a 1 x moles of a & moles of a required, n a 7 x 6.82 molo z 11-a moles. use deal gas equation, oC -2731 PV z nar latm x 2 11-94 males xo-osoittalmx 27 k. motk & 2 267.561 262680 NH3 + a Now + Hua balancet 2 Nr to - 2Not 3409) balance 0.- 2NH + 50 → zno+ 3M0. 14 Nhz + so 4 Not 640)

PV = nRT volume, u 2 moles (n) from reaction, 4 w so 10 02 Nn give 4L NO. give ? 100L NO SL a so 12 Lo que can 4L NO give ? No homes 2 nxy 29.61 No. So no produced so o acts as o volume No from G is less, limiting realhant produced a volume no Chromo 2 1961 U21-ool Puz ner Pressure pressure a moles of gas 2 mass molar mass (mass also same for both gases So Pressure a 1 molar mass a we know molar mass of H ess, molar mass of N. more. higher pressure Container with H gas (due to lower molar mais contains more moles container with the gas (Same mass, so moles is inversly proportant to molar mass) contains more molecules C h gas contaner (t mole contains Avogadro number (Golux 1823) number of molecules, males a number of moleares)

Both containeus d) has have greater same Kimenc energy – kinene energy Temperchure & gas) C kinerne (both energy at same 2 absolute temperature) e has more with more speed molecules that gas container Mums a molar mass
