Because energy cannot be created or destroyed, only transferred
N2(g) + 3H2(g) =2NH3(g)
Number of moles of reactants > product...
Therfore if pressure is increased.
Equilibrium is disturbed according to LCP....
Equilibrium shift to the right (product)
......
If you want to understant the fundamental concept:
Take for example 2A + 3B = 4C
Reactant: 5 moles (5 volumes)
Product: 4 moles (4 volumes)
When pressure of a gas is increased, volume decreases!
(Vice-versa)
If pressure is increased, volume decreases. Hence number of collisions INCREASES(constrain). Equilibrium shifts in such a direction so as to decrease the number of collision accordinf to LCP...
This happens when number of paeticles decreases as equilibrium shift forward because the forward reaction is accompanied by a decrease in number of particles (5 to 4)
Answer:
69.152 % → 63Cu
30.848 % → 65Cu
Explanation:
As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.
Hydrogen bonding occurs between polar molecules that have a hydrogen atom that is directly bonded to a nitrogen, an oxygen, or a fluorine atom. That creates an extremely polar molecule with a permanent net dipole moment.
A hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group, and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted Dn–H···Ac, where the solid line denotes a polar covalent bond, and the dotted or dashed line indicates the hydrogen bond.The most frequent donor and acceptor atoms are the second-row elements nitrogen (N), oxygen (O), and fluorine (F).

Answer:
three parts alcohol and seven parts water.
Explanation:
The total ounces of solution formed = 20 ounces
The solution of volume 12 ounces has one part alcohol and two parts water.
If there are three parts of solution, there is one part alcohol and two parts water.
for 12 ounces we have = 4 ounces alcohol and 8 ounces of water.
for 8 ounces of solution we have one part alcohol and three parts water.
It means in 8 ounces we have = 2 ounces alcohol and 6 ounces of water.
The total ounces of alcohol in the solution after mixing = 4 + 2 =6
the total ounces of water in the solution after mixing = 8 + 6 = 14
Thus the ratio of alcohol to water = 6:14 = 3: 7
it means three parts alcohol and seven parts water.
