Who discovered the empirical formula?
The empirical formula of a compound is determined based on the simplest whole-number ratio of the atoms present in the compound. It was not "discovered" by a single individual, but rather developed through the work of many scientists over time. Some key contributors to the development of empirical formulas include John Dalton, Jöns Jacob Berzelius, and August Kekulé.
What is the molecular compound name for hydrazine N2H4?
It's empirical formula would be NH2. An empirical formula represents the ratio of the atoms in the compound, rather than the actual number. You can work this out by dividing by a common denominator (in this case, 2).
When do gastric acid inhibitors work best?
Gastric acid inhibitors work best when taken before a meal to prevent excess acid production in response to food intake. They are most effective when used consistently as prescribed by a healthcare provider to control symptoms of acid reflux or peptic ulcers.
What is the empirical formula of a hydrocarbon with 85.7 mass carbon?
* Carbon = 79.9g, hydrogen = 20.1g (work out the mass of each element) * 79.9/12 = 6.66, 20.1/1 = 20.1 (divide mass by atomic mass number) * Ratio = 6.66 : 20.1 = 1:3 (simplify to find lowest ratio) * Therefore the simplest ratio and the empirical formula is CH3.
How do buffers work in chemistry to maintain a stable pH level?
Buffers in chemistry work by resisting changes in pH when an acid or base is added. They contain a weak acid and its conjugate base, or a weak base and its conjugate acid. When an acid is added, the base in the buffer neutralizes it, and when a base is added, the acid in the buffer neutralizes it. This helps maintain a stable pH level in a solution.
What is empirical formula for tellurium Oxide?
from my work and looking around i think it is TeO2
What is the empirical formula for mercury oxide . Please show work.... Thank you?
Mercury oxides are: HgO and Hg2O.

A compound has a mass of 16.7g 12.7g Iodine 4g Oxygen Therefore the empirical formula is I2O5 What additional information do you need to work out the molecular formula?
To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.

Why are molecular formula of a compound such more useful to a forensic scientist than the empirical formula?
The molecular formula provides the exact number of atoms of each element in a compound, while the empirical formula gives the simplest whole number ratio of elements. This specificity in the molecular formula is crucial for identification and analysis in forensic science, as it helps determine the exact composition of a substance.
How can you find the molecular formula of a compound when its percentage composition is given?
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)
When 97.5grams of zinc was heated in oxygen 121.5grams of zinc oxide was formed calculate the empirical formula of the oxide?
This is how to work it out:Elements that combine:Zinc+OxygenMasses that combine:97.50 g121.50 gRelative atomic mass (Ar):65.40g16 gMoles of atoms that combine:97.50/65.40 = 1.49...`121.50/16 = 7.59375Ratio in which atoms combine:1.49... : 7.59375 OR 1 : 5 (simplified)Empirical formula (the simples ratio in which atoms in a compound are combined) should be ZnO5This is the method that should be used to work it out, although just check for yourself that the answer is right as usually the actual formula for zinc oxide is ZnO - so just check that it's right
