Can anyone help me to understand this concept?

Question

Na +Cl --> NaCl
1 mole of sodium plus 1 mole of chlorine produces 1 mole of sodium chloride. Shouldn't that make 2 moles of sodium chloride? (1+1=2) I really don't understand this concept.

Answer 1

NO, it makes one mole of a new material -- the salt sodium chloride. The single mole of sodium chloride **molecules** still has two moles of **atoms** -- one mole of sodium atoms, and one mole of chlorine atoms.

A mole does not refer to specific things -- I can have a mole of atoms, a mole of molecules, a mole of grains of sand, or a mole of bottlecaps. A mole refers to a specific number of things -- Avogadro's Number, 6.023E23.

Answer 2

No, because a mole is a specific number of particles. When a sodium ion reacts with a chloride ion, it produces a new particle, a molecule of a compound, and it takes a mole of each ingedient to produce a mole of these 2-atom molecules. Substitute "dozen" for "mole" and you'll get the idea more easily.

Answer 3

This equation is not exactly the same as 1+1 = 2.

It only means 1 mol of Na + (combined with) 1 mol Cl --> (produces) 1 mol NaCl.

so in this case 1 + 1 = 1
1 element plus 1 element equals 1 substance...

but remember, this only applies to this example.

let's say NaCl + H20 --> NaOH + HCl
1 mol of Na bonded with 1 mol of O and H. the other mol of H bonded with Cl.

Answer 4

No because Na+ + Cl¬ - -----> NaCl. Na has a positive ion and Cl has a negative ion. So,,,,positive + negative = zero.

Answer 5

If one cube of sugar goes with one cup of coffee....and you have 100 cubes and 100 cups, then you have 100 cups of coffe with sugar.

Answer 6

its like if u had a one pound lump of white clay and a one pound lump of black clay and mixed them together. you may have a 2 pound lump of gray clay now but it is still only one lump of gray clay.
