Each water molecule contains two hydrogen atoms (#M = "1.0079 g/mol"#) and one oxygen atom (#M = "15.999 g/mol"#). Therefore, the molar mass is:

Through multiple reactions, a chemist uses C, CaO, HCl, and H2O to produce dichlorobenzene, C4H4Cl2. Assuming that the efficiency of this lab is a minimum of 65.0%, how many molecules of …

An organic compound was taken for combustion.14.77 g was burned in oxygen.The result of combustion gave 43.26g of CO2 &12.40g of H2O.Determine the empirical formula?

Given the following equation: C6H8O7 + 3NaOH --> Na3C6H5O7 + H2O. What is the percentage by mass of citric acid in the orange juice? How many grams of HCI are there in 100.0 mL of …

Complete combustion of C14H18O7 to CO2 and H2O. You have 315.0000 grams of C14H18O7. How many grams of O2 are required? How many grams of CO2 are generated? How many grams of H2O …

Nov 28, 2017 · Why can you only add oleum to water to get SO2 (g) industrially instead of adding SO3 (g) to H2O (l) immediately?

Changes in state are physical changes. Let's take water as an example. H2O. In the gaseous state, we sometimes call it steam or water vapor; it's chemical formula is still H2O. In the liquid state and in the …

Nov 1, 2017 · There is an old joke on the dangers of dihydrogen monoxide. But of course "dihydrogen monoxide" is simply water, i.e. H_2O...and a chemist would never call it anything but water or H_2O. …

Oct 27, 2017 · The trade in energy sucks for H2 (but not so much for water), so the H2⋯H2O interaction is highly unfavored for H2, compared to the H2⋯H2 and H2O⋯H2O interactions. So, H2 is very …

Nov 17, 2015 · You would balance it stoichiometrically. Equal masses must occur on both sides of the equation. If there are 2 xx K atoms on the left hand side of the equation, there must be 2 K atoms on …
