Let me ask u another question
Theoretically, how many moles of NH3 will be produced
I believe it's 2 Moles of NH3 because that's how many there are in the balanced equation. Is it right if so
How should i get the actual yield of NH3 if the percent yield is 80%, how many moles of NH3...
6.0 moles of N2 thats are mixed with 12.0 moles of H2 according to the following equation:
The equation is already balanced:
N2(g)+ 3H2(g) yields 2NH3 (g)
The questions asks for what is the chemical in excess? is it H2 or N2
I solved the problem but i want to make sure if it is right...
idk if i did this correctly so far so here goes.
The question states
A large rubber ball (8.80 kg) is fired straight down from the roof of a building from a spring loaded mechanism that stored 987 J of elastic potential energy. The building roof is 14.0 meters above ground. The rubber...
