How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen This is the formula for the reaction?
4Na + O2 -> 2Na2O
10 moles Na (2 moles Na2O/4 moles Na)
= 5.0 moles Na2O produced
When you have 46 grams of sodium react with 160 grams of oxygen how many moles of sodium oxide are obtained?
The equation for the reaction is 4 Na + O2 -> 2 Na2O. This shows that, for complete reaction, one mole of oxygen is required for each four gram atomic masses of sodium. The gram atomic mass of sodium is 22.9898; therefore, 46 grams of sodium constitutes 2.00 moles of sodium, to more than the justified number of significant digits. The gram molecular mass of diatomic oxygen is 31.9988; therefore 160 grams of oxygen constitutes…
The reaction between sodium and water will produce sodium hydroxide and hydrogen. The reaction will also produce energy in the form of light and heat. This heat will ignite the remaining sodium, followed by the ignition of the hydrogen produced (hydrogen will react with the oxygen in the surrounding air). The result will be an explosion.
Sodium and oxygen are combined to form some kind of oxide of sodium, but there are three different ones. The specific kind produced will be determined by the conditions under which oxidation occurs. When burned in air, sodium will form sodium peroxide (Na2O2). If there is a limited amount of oxygen, sodium oxide (Na2O) will form. Lastly, sodium superoxide (NaO2) will be produced if sodium is burned in oxygen under pressure. Wikipedia has some extra…
The reaction between citric acid and sodium bicarbonate (baking soda). is an acid base reaction. This reaction produces water, carbon dioxide, sodium hydrogen citrate, and sodium citrate. The relative amounts of sodium hydrogen citrate and sodium citrate produced depend on the amount of citric acid added.
How much sodium nitrate is produced when 1.7G of silver nitrate and 1.5G of sodium iodide is reacted?
The equation for the reaction between silver nitrate and sodium iodide is AgNO3 + NaI -> AgBr + NaNO3. The gram formula masses are 169.87 for silver nitrate, 149.89 for sodium iodide, and 84.99 for sodium nitrate. Therefore, 1.7 g of silver nitrate constitutes 1.7/169.87 or 0.010 formula mass of silver nitrate and 1.5 g of sodium iodide constitutes 1.5/149.89 or 0.010 mole of sodium iodide, to the justified number of significant digits. The reaction…
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.
