A 20.2g chunk of magnesium metal reacts with 13.7 g of oxygen gas to make magnesium oxide. Write the balance equation. Write the chemical formula, balanced equation, and state the type of reaction for magnesium reacting with ox...
The oxidation reaction of a compound is the same as the combustion of that compound with O2 gas. If the exact chemical formula and amount of the compound are known, then the oxygen required can be obtained from the balanced chemical equation ...
Nernst equation The reversible voltage of hydrogen-oxygen fuel cells under the standard condition (298.15 K, 1 atm, 101,315 Pa) is calculated in Eq. (1.19). For other conditions, the reversible voltage will certainly change. Temperature and gas reactant concentration are two main factors affecti...

We predict the amount of product that can be formed in a chemical reaction in stoichiometry. Stoichiometric calculations always use the balanced chemical equation. In addition, we must determine the limiting reagent. This reagent is the...
Chemical oxygen demand formula COD tests help us evaluate the amount of organic pollutants in water. So, it is somewhat crucial to know the equation behind said tests. The chemical oxygen demand formula is: COD=(A−B)×N×8000Sample volumeCOD=Sample volume(A−B)×N×8000 where: CODCOD...
Oxygen in marine sediments regulates many key biogeochemical processes, playing a crucial role in shaping Earth’s climate and benthic ecosystems. In this context, branched glycerol dialkyl glycerol tetraethers (brGDGTs), essential biomarkers in paleoenv
