the reaction is
2NO(g) + 2H2(g) <—> N2(g) + 2H2O (g)
Kc = [N2] [ H2O]^2 / [NO]^2 [ H2]^2
Given
moles of NO = 0.124 therefore [NO] = moles /volume = 0.124 /2 = 0.062
moles of H2 = 0.0240 , therefore [H2] = moles / volume = 0.0240 / 2 = 0.012
moles of N2 = 0.0380 , therefore [N2] = moles / volume = 0.0380 / 2 = 0.019
moles of H2O = 0.0276 , therefore [H2O] = moles / volume = 0.0276 / 2 = 0.0138
Kc = (0.019) ( 0.0138)^2 / (0.062)^2 ( 0.012)^2 = 6.54
Since there are 63.01284 grams to one mole of HNO3, then 12.5 moles would be in 450 grams of it.
Answer:
the motion of molecules increases
A compound can be treated like an element when balancing chemical equations when : A. when there is no change to the atoms in the compound
If they remain together during the reaction, you can treat a compound as a singe atom.
hope this helps
Answer:
There are alot of facts but here are a few
Explanation:
Atoms:
There are 3 parts to an atom
Protons have a positive electrical charge
Atoms are the smallest particles to make an element
Elements:
Hydrogen is the most common element in the world
An element is a substance that is made entirely from one type of atom.
An element is a substance that cannot be broken down into any other substance.
