Where would you find 79 percent nitrogen 16 percent oxygen 4.5 percent carbon dioxide?
In the air around you.
What is the oxidation number of sodium carbonate?
We can find this in bleaching powder. Chlorine shows +1 oxidation number.
How do you find the chemical formula of sodium oxide?
Well you should know the formula and valency of each element first, Sodium formula - Na valency - +1 Oxide formula - Oxygen - O valency - (-2) Since the charge of the compound has to be 0 (zero) 2 atoms of sodium (+2) are required to neutralize the effect of the one oxygen atom (-2) ----------- [2 + (-2) = 0] Na2O
What the answer for to find the number of moles equal to 1.48 10 24 molecules na2o?
If you mean 1.48 x 1024 molecules, just divide by 6.022 x 1023 = 2.46 moles
How many electrons in Sodium Oxide?
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.

In the air around you.
What percent of O and N can you find in the atmosphere?
78% Nitrogen 21% Oxygen
How do you find theoretical percent of water?
Water contain 88,88 % oxygen and 11,11 % hydrogen.
Where can you find oxygen hydroxide in nature?
Its water.... so over 70 percent of the earths surface
What is the oxidation number of sodium carbonate?

What should I do if my 4 year old boy's oxygen level is 89 percent?
Oxygen levels should be 98% or higher. Find professional help at a hospital. Right now!
What are the steps on finding what the mass of oxygen in a 10 g of zircon?
Well, the formula for zircon is ZrSiO4 so, this means that you need to find the molar mass of the entire thing. Once you have this you find the percent mass that oxygen takes, by dividing the mass of the oxygen by the mass of the total compound. Then you multiply this number by the 10g and voila.

Where can one find medical oxygen solutions?
One can find medical oxygen solutions from the following sources: Health Oxygen, Portable Oxygen, Oxygen Solutions, Alternative Oxygen Solutions, to name a few.
How do you Find a whole when the percent is known?
how do you find a number when a percent of it is known
How do you increase by 17 percent?
The way I find percentages is: To find 17% I: Find 10 percent, Then half the 10 percent, to get 5 percent which makes 15%. Then find a 5th of the 5 % and double it to make 17%
