Laughing Gas, N2O, is made by the careful decomposition of ammonium nitrate
NH4NO3 (s) = N20 (g) + 2H20 (g)
How many grams of N2O can you obtain?
How many dm3 of stream would also be produced?
Not interested in the name of your high school. It is important that you say chemistry though so you do not get a cranky old physicist looking at your question.
There is no way to tell how much comes out without knowing how much went in.
To calculate the number of grams of N2O obtained, you need to know the amount of NH4NO3 used or have enough information to determine it. However, the question doesn't provide this information. If you have the amount of NH4NO3, you can use stoichiometry to calculate the amount of N2O produced.
Here's an example of how to calculate the number of grams of N2O:
Step 1: Determine the molar mass of N2O
The molar mass of N2O is calculated as follows:
N (14.01 g/mol) * 2 + O (16.00 g/mol) = 44.02 g/mol
Step 2: Set up a stoichiometric ratio
From the balanced chemical equation (NH4NO3 -> N2O + 2H2O), the ratio between NH4NO3 and N2O is 1:1. This means that for every 1 mole of NH4NO3, 1 mole of N2O is produced.
Step 3: Calculate the number of moles of N2O
To calculate the number of moles of N2O, you need to know the number of moles of NH4NO3 used or have enough information to determine it.
Step 4: Convert moles of N2O to grams
Multiply the number of moles of N2O obtained in step 3 by its molar mass to find the number of grams.
Regarding the second part of the question, there is no direct information in the given equation about the production of steam (H2O). Therefore, it is not possible to determine exactly how many dm3 (cubic decimeters) of steam would be produced without further information.
