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...
Thanks everyone (Samba especially)! I 'completed' the assignment last week - Looks like I got one right. I just guessed though because I couldn't figure out how to find the amount of moles to use in the PV=nRT equation. I'm still pretty fuzzy about that but thankyou so much Samba your step by...
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)...
Looking over my notes, it looks like you hit it right on! I'm still a *little* fuzzy but I can't thank you enough for helping me out. I was gonna have to submit this with no idea what I was doing.. :) Any help at all is better than no help. Thankyou SO much for your help.
This is the question:
Balance the equation and Calculate the enthalpy change for the following reaction:
NH3(g) + O2(g) --> N2(g) + H2O(l)
NH3(g)= -46.11 kj/mol
O2(g) = 0 kJ/mol
N2(g) = 0 kJ/mol
H20(l)= - 285.830 kJ/mol
I know that to begin, I need to multiply the numbers above by the...
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...
Ok! So here's the correct balanced equation:
4NH3 + 3O2 ----> 2N2 + 6H2O
Keeping in mind the problem:
Now, I already know this (I didn't figure this out, it was provided to me):
NH3(g)= -46.11 kj/mol
O2(g) = 0 kJ/mol
N2 = 0 kJ/mol
H20= - 285.830 kJ/mol
So now I need to...
Whoops! This is an example question!! Sorry sorry - here's the real problem! This is what I'm trying to figure out how many mols to times by. :o :D
Balance the equation (Already did this) and Calculate the enthalpy change for the following reaction:
NH3(g) + O2(g) --> N2(g) + H2O(l)
NH3(g)=...
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!!
