Closer to the surface, where the pressure is lower, there’s another obstacle to decomposition—the interior of a mole planet is low in oxygen. Without oxygen, the usual decomposition doesn’t happen, and the only bacteria that can break down the moles are those which don’t require oxygen...
Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol This is the number of moles in ...

We can still deduce the stoichiometry of this reaction even if we do not know the mass of oxygen that reacted. The ratio of hydrogen to water is 1 : 1. But there is only one atom of oxygen in a molecule of water – half the amount in an oxygen molecule. So the mole ratio o...
calculate the mass in grams of 3.6 mol of h 2 so 4 . solution look for the atomic masses of hydrogen, sulfur and oxygen. h = 1.008 s = 32.06 o = 16 therefore, the molecular mass of h 2 so 4 is 2(1.008) + 32.06 + 4(18) = 106.076 hence, one mole of h 2 so 4 weights ...
This reaction is not balanced, however, because the left side contains two oxygen atoms and one chlorine atom, whereas the right side contains two chlorine atoms and one oxygen atom. The balanced form of this equation would be Ca(OH)2 + 2 HCl → CaCl2 + 2 H2O, which contains the same...
First, balance oxygen. We note that the ratio of oxygen is 2:1, so we know we have to double the compound on the right (1) in order to equalize the ratio. Now, our equation looks like this: ___ H2 + _1_ O2 <---> _2_ H2O We can see now that there are two oxygen on ...
Answer the following questions. You may use a calculator A sample of a monoprotic acid was analyzed. The sample contained 40.0% C and 6.71% H. The remainder of the sample was oxygen. a.Determine the empirical formula of the acid.
