given the reaction 4Na(s) +O2 -> 2Na2O How many grams of Na2O can form from 3.0g of Na? use these molecular weight Na=23g/mol

kolezko [41]

No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol

Mr of Na2O = 23+23+16 = 62 g/mol

n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol

m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g

The number of water molecules per ionic molecule in a hydrate is called the ___________. A. electronegativity B. anhydrous numbe

arlik [135]

Answer:

C. hydration number

Explanation:

When we dissolve an ionic compound (a charged species) the charges can interact with the water molecule. In the case of cations (positive charges) the negative dipole of water (generated in the oxygen) will interact with the positive charge at the same time the anions (negative charges) the positive dipole of water (generated in the hydrogen).

The amount of water molecules that can interact with a single ion (cation or anion) is called hydration number. In the example, we have a hydration number of "4" for the sodium cation.

I hope it helps!
