Oxygen is lost from the water body by the respiration of animals and plants and also by decomposition of organic matter.

WebbThe water is pushing against the sides of the glass, but not enough to do anything. Add a little energy - and knock the glass over - and all the water qwill promptly move to the floor. When oxygen and hydrogen are found in the atmosphere, they are mostly bonded to themselves: two oxygen atoms, two hydrogen atoms. WebbThere are two key methods used to obtain oxygen gas. The first is by the distillation of liquid air. The second is to pass clean, dry air through a zeolite that absorbs nitrogen and leaves oxygen. A newer method, which gives oxygen of a higher purity, is to pass air over a partially permeable ceramic membrane.
WebbInstead, since we know the molar mass of carbon dioxide, we can measure out a comparable mass. Carbon dioxide has a molar mass of 44.01 g/mol, so 7 moles of carbon dioxide corresponds to. 44.01 g/mol×7 = 308.07 … Webb30 mars 2024 · Convert 72g of water into moles of water using molecular weights.

WebbIn the reaction of hydrogen and oxygen gas to produce water, 10.0 grams of hydrogen are mixed with 40.0 grams of oxygen. What is the limiting reagent, and how many excess grams of the other is left over? 2 H 2 + O 2 ---> 2 H 2 O a) Hydrogen is the limiting reagent and 30.0 grams of oxygen are left over.
Webb8 juni 2024 · So for every mole of #H_2# you will form a mole of water, assuming you have sufficient oxygen to react with it all. The atomic weight of hydrogen atoms is 1, but the molar mass of diatomic #H_2# is 2 g/mol. ... The molar mass of water is 18 g/mol so you will form 4 x 18 = 72 g of water. Answer link.
