I have to write a little report on an industry that uses a chemical reaction(s) and basically answer these questions (skip down to the bottom if you just want to see my quick question):
~~~~~~~~~~
1. Identify chemical reactions upon which the industry relies.
2.Write the chemical equation...
Here is the example I was given:
------------------------------
Example:
How many liters of hydrogen gas can be produced at 290 K and 2.5 atm if 40.0 g of sodium react with excess water according to the following equations:
2 Na(s) + 2 H2O(l) --> 2 NaOH(l) + H2(g)...
How do I figure out how many moles to mutiply by?
It says "multiply by the number of moles of that substance"
How do I figure that out?
Here's where I am:
H2O(l)= - 285.830 kJ/mol x ___ mol
NH3(g)= -46.11 kj/mol x ___ mol
---
And what does the L or G mean for the...
I hate stoichiometry.
Here's the problem:
How do I figure out how many mols to multiply for each product and reactant? I've already been given the other part of the equation.
Thanks
Please help me I am so lost!!
Here's the lesson. My writing is in Blue.
Where should I start? I am that confused; I feel like :cry:
Thanks for your help!!
