The calculated amount of oxygen required to oxidized a compound to its final oxidation products . The organic matter of sewage is mainly composed of carbohydrats , protein, fats,and products of their decomposition . If the chemical formulaeof the organic matter are called as theoretical oxygen demand can be calculatd.

Percent error of O in MgO?

To calculate the percent error of oxygen in magnesium oxide (MgO), you would compare the experimental value of oxygen in MgO to the theoretical value. The experimental value can be determined by chemical analysis, while the theoretical value can be calculated using the molecular formula of MgO. The percent error is calculated using the formula: (|Theoretical value - Experimental value| / Theoretical value) x 100%.


What if a potassium chlorate sample is contaminated with moisture. Would an analysis show the experimental oxygen higher or lower than the theoretical oxygen?

The experimental oxygen would be higher than the theoretical oxygen in a contaminated sample of potassium chlorate. This is because the moisture would contribute to the sample's weight when measured, resulting in a higher oxygen content calculation compared to the theoretical amount based on the chemical formula.


Would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?

The experimental percent oxygen may be lower than the theoretical percent oxygen due to factors such as experimental error, incomplete reactions, or impurities in the sample. Variability in experimental conditions can influence the accuracy of the results obtained.


What causes biochemical oxygen demand?

Biochemical oxygen demand (BOD) is caused by the presence of organic pollutants in water, such as sewage, agricultural runoff, and industrial effluents. These organic pollutants provide a food source for bacteria, which consume oxygen as they break down the pollutants, leading to a decrease in oxygen levels in the water.


What is the theoretical yield of aluminum oxide if 3.00 mol of aluminum metal is exposed to 2.55 mol of oxygen?

The balanced chemical equation for the reaction is 4Al + 3O2 -> 2Al2O3. Since the molar ratio between aluminum and oxygen is 4:3, aluminum is the limiting reagent. Therefore, the theoretical yield of aluminum oxide is based on the 3.00 mol of aluminum. Using stoichiometry, the theoretical yield of aluminum oxide would be 3.00 mol of Al * (2 mol Al2O3 / 4 mol Al) = 1.50 mol of Al2O3.

6 How much is the theoretical oxygen demand of 1mM acetate solution?

The theoretical oxygen demand (ThOD) of acetate is 2 moles of O₂ per mole of acetate. To calculate the ThOD of a 1mM acetate solution, you would convert mM to moles (1 mM = 0.001 moles) and then multiply by the ThOD (2 moles O₂/mole acetate) to get 0.002 moles of O₂.


What is the different between biochemical oxygen demand and biological oxygen demand?

Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .


Why is there a demand for chemical oxygen?

There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.


What is mean chemical oxygen demand-?

The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.

What is a biological oxygen demand?

A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.

How does the temperature of water effect the dissolved oxygen?

Well, dissolved oxygen impacts water quality because if the level of the dissolved oxygen is too low then organisms can die. _________________________________________________________________ That is okay, but I want to what dissolved oxygen tests for. ------ For the water quality are tested: - total oxygen demand (TOD) - biochemical oxygen demand (BOD) - chemical oxygen demand (COD) - sometimes, carbonaceous biochemical oxygen demand (CBOD) For details about the analytical procedures I recommend you to read a book or a collection of analytical methods for water, searching in a library or searching on the Internet.
