The standard nasal cannula delivers an inspiratory oxygen fraction (Fi[O.sub.2]) of 24-44% at supply flows ranging from 1-8 liters per minute. The formula is Fi[O.sub.2] = 20% + (4 x oxygen liter flow). The Fi[O.sub.2] is influenced by br...
The empirical formula for a substance is essentially the lowest common denominator of the elements involved. For example, the formula for glucose is C6H12O6 but its empirical formula is CH2O.Answer and Explanation: Since carbon, oxygen, and chlorine are all pure elements their empirical formulas as...

What is the formula of the hydride formed by strontium? Strontium Strontium is an alkaline earth metal. On the Periodic Table of Elements, strontium is given the symbol 'Sr' and the atomic number 38. Strontium is a solid at room temperature and has a melting point of 1431 degrees Fahrenheit...
also known as fermentation, is a process similar to glycolysis. It generates energy in the absence of oxygen as an electron acceptor. In most eukaryotic organisms, glucose serves as both an energy storage unit and an electron donor. The equation for glucose being converted into lactate is:
The chemical formula of nitric acid isHNO3and it is made up of one hydrogen atom, one nitrogen atom, and three oxygen atoms. What is nitric acid made of? Nitric acid is made byreaction of nitrogen dioxide (NO2) with water. The net reaction is: 3 NO2+ H2O → 2 HNO3+ NO. Normally...
The process of photosynthesis is commonly written as: 6CO2 + 6H2O→ C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen ...
