What is 2NaOH? - Answers
WebA mole2(mol) is a number of things equal to the number of atoms in exactly 12 g of carbon-12. Experimental measurements have determined that this number is very large: 1 mol = 6.02214179 × 1023things Understand that a mole means a number of things, just like a dozen means a certain number of things—twelve, in the case of a dozen. WebFor example, theatomic mass of an oxygen atom is 16.00 amu; that means the molar massof an oxygen atom is 16.00 g/mol. Further, if you have 16.00 grams of oxygen atoms, you know from the definition of a mole that your sample contains 6.022 x 10 oxygen atoms. The concept of molar mass can also be applied to compounds. WebDec 17, 2024 · The correct answer is reactants 2Na and 2H₂O and products 2NaOH and 1H₂. The given unbalanced chemical equation is: Na (s) + H2O (l) → NaOH (aq) + H₂ (g) From the equation, it can be seen that there are three atoms of hydrogen on the products side, however, only two on the reactant's side. the age victorian election
