2H2(g) + O2(g) → 2H2O(1) 0 260 g 0.2068 0.180 g 2008
When 45.0 g of CH4 reacts with excess O2, the actual yield of CO2 is 118 g. What is the percent yield? CHA(g) + 2O2(g) - CO2(g) + 2H2O(g) 73.6% 67.9% 95.2% 86.4%
For the reaction: 2503(g) + 790 kcal - 25(s) + 3O2(g), how many kcal are needed to form 1.5 moles O2(g)? 790 kcal 395 kcal 2370 kcal 411 kcal
When 3 moles of Ny are mixed with 5 moles of H2 the limiting reactant is N2(g) + 3H2(g) - 2NH3(g) H2 NH3 ОООО H20 O N₂
I can’t see the whole question......
1 mole ----------- 6.02x10²³ atoms
1.75 moles ------- ?
atoms = 1.75 * 6.02x10²³ / 1
= 1.053x10²⁴ atoms
hope this helps!
When you are making a cake "for example" you put all the ingrediants together.. thrn put it in the oven.. the combination that makes the cake look like that or that combines the ingrediants together is by chemical reaction.
