Matter is everything around you, atoms and molecules are all composed of matter.
I believe the answer is "Bohr's model explains the chemical behavior of all atoms."
Answer:
The diluted solution is 0.65 M
Explanation:
Dilution formula to solve the problem is:
M concentrated . V concentrated = M Diluted . V diluted
We can also make a rule of three though.
In 1000 mL of concentrated solution, we have 13.1 moles of HNO₃
So in 25 mL we have (25 . 13.1 ) / 1000 = 0.327 moles of HNO₃
This moles are also in 0.500 L of diluted solution, the new molarity will be:
0.327 mol / 0.5L = 0.65 M
Molarity of diluted solution must be always lower than concentrated solution, otherwise the excersise is wrong.
If we replace in the formula
13.1 M . 25 mL = 500 mL . M diluted
M diluted = 13.1 m . 25 mL / 500 mL = 0.65 M
The equation for the production of Ammonia is:
N₂ + H₂ → NH₃
N₂ + H₂ (LeftHandSide of equation) : 2 Nitrogen atoms; 2 Hydrogen atoms
NH₃ (RightHandSide of equation): 1 Nitrogen Atom; 3 Hydrogen atoms
To balance the equation you must place in front of each compound/molecule/element that makes the amount of atom of each element equal on both sides of the equation.
N₂ + 3H₂ → 2NH₃
LHS RHS
Nitrogen 2 2
Hydrogen 6 6
So essentially the set of coefficients you use to balance the equation are 1 for N₂, 3 for H₂ and 2 for NH₃.
