Yes, each element on the periodic table has a unique name and chemical symbol.
There is no element with the symbol ma2 on the periodic table.ma2 is a formula for a di atomic element like oxygen-O2 and Hydrogen-H2.The element with a similar symbol like ma is Magnesium-Mg
Fe is the chemical formula for the element iron in the periodic table, whenever you see it it means iron.
No, gluten is a molecule not an element. Gluten's chemical formula is C29H37N5O9.
Niacin is a compound, not an element, and doesn't have a "symbol". Its molecular formula is C6H5NO2.
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
· Assume that you have 100.0 g sample of the compound · Calculate the amount of each element in the sample · Convert the mass composition of each element to a composition in moles by dividing by the appropriate molar mass

YES.For one to know the percentage composition,the amount of moles of the reacting element must be considered using the compound. •Well you dont really have to know just the formula. You can eaither use the formula if its given or the molar mass if its given. i just recently did a test where i was given either the Molar mass or Formula name and i had to figure out the percent composition. so it depends on the info given.
N2 is the chemical formula of the diatomic molecule of nitrogen. The periodic table contain the element as N.
To work this out you need the formula of the compound and your periodic table to tell you the relative atomic masses of each element. First add up all the relative atomic masses to get the relative formula mass. Then for each element in turn, take its relative atomic mass (multiplying up if there is more than one of it in the formula) and divide by the relative formula mass, then multiply by 100 to get a percentage. I'm not going to give you the answer - partly because then you'll never practise doing it for yourself, and partly because I wonder if you meant magnesium permanaganate, or the more usual school compound of potassium permanganate, KMnO4.
