because Na- is sodium and the charge for sodium is +1
but NO3 is a -1
so when you Cris cross them:
your formula should look like this.
Na+1NO3-1= +1 and -1 cancel out and you are left with NaNO3
:) hope it helped.
To find the grams of oxygen in 765g of Na2O, we first need to calculate the molar mass of Na2O. This can be done by adding the atomic masses of sodium and oxygen. The molar mass of Na2O is 61.98 g/mol. Since there are 2 oxygen atoms in 1 molecule of Na2O, the molar mass of oxygen is 32 g/mol. So the mass of oxygen in 765 g of Na2O would be (2*32)/61.98 * 765g.
The chemical formula for sodium oxide is Na2O (with the '2' written in subscript). So in one formula unit of sodium oxide, there is one sodium and two oxygen. 1 mole of sodium oxide would have 3 x 6.02 x 10^23 = 1.81 x 10^24 atoms.Sodium oxide is made of sodium and oxygen atoms. The chemical formula of it is Na2O. There are 3 atoms in 1 molecule of Na2O.
Na2O is sodium oxide. It contains the elements, sodium and oxygen. The chemical formula tells us that there are 2 sodium atoms and 1oxygen atom . It is a highly reactive compound, which will readily dissolve in water to form sodium hydroxide. Na2O + H2O = 2NaOH .
There are two sodium atoms in each molecule of Na2O, as indicated by the subscript immediately after the symbol for sodium atoms in the formula.
Since Na2O is an Ionic compound. it does not have any shape.

Sodium oxide is a compound, two sodium atoms for each oxygen atom, or Na2O (if I could do the subscript).
The formula of the product would be sodium oxide (Na2O). Sodium metal reacts with oxygen gas to form sodium oxide, where two sodium atoms combine with one oxygen atom.
Nothing.4 atoms of sodium would have a 4 + charge and 5 atoms of oxygen would have a 10 - charge.So you need 2 atoms of sodium and 1 atom of oxygen to get...,Na2O=====
The compound Na2O is formed through a reaction between sodium metal (Na) and oxygen gas (O2). During this reaction, the sodium atoms lose electrons to become positively charged ions (Na+), while the oxygen atoms gain electrons to become negatively charged ions (O2-). These ions combine to form the ionic compound Na2O.
The chemical formula for sodium oxide is Na2O.
