2015年10月23日 · The empirical formula for acetic acid is "CH"_2"O". "CH"_3"COOH" can be written as "C"_2"H"_4"O"_2". An empirical formula represents the lowest whole number ratio of elements in a compound. The subscripts in the formula "C"_2"H"_4"O"_2" can be reduced to the simplest whole number ratio by dividing the subscripts in the molecular formula by 2.

2015年11月12日 · You would divide the numbers of each atom in the molecular formula by their highest common factor. > The empirical formula is the simplest possible formula for a compound. The subscripts of the elements in the empirical formula must be in the smallest possible ratio. We can write the molecular formula "CH"_3"COOH" as "C"_2"H"_4"O"_2. The ratios of "C:H:O" …

2017年6月8日 · Acetic acid, #"CH"_3"COOH"#, will react with sodium hydroxide, #"NaOH"#, to produce sodium acetate, #"CH"_3"COONa"#, and water. The unbalanced chemical equation that describes this neutralization reaction looks like this

2016年6月22日 · The empirical formula is the simplest whole number ratio that defines constituent atoms in a species. Given the defintion, the empirical formula of H_3C-CO_2H, C_2H_4O_2, = CH_2O. The molecular formula, as it is here, is always a multiple of the empirical formula.

2017年3月5日 · Therefore, you can say that the reaction between sodium bicarbonate and acetic acid will produce aqueous sodium acetate, water, and carbon dioxide "NaHCO"_ (3(aq)) + "CH"_ 3"COOH"_ ((aq)) -> "CH"_ 3"COONa"_ ((aq)) + "H"_ 2"O" _ ((l)) + "CO"_ (2(g)) uarr This is a classic example of a neutralization reaction in which sodium bicarbonate, or ...

2015年10月22日 · "CH"_2"O" The empirical formula tells you what the smallest integer ratio between the atoms that make up a substance is. In essence, the empirical formula can be thought of as the building block of a substance. The molecular formula will thus tell you how many building blocks are needed to form that substance. So, for a given molecule, the empirical formula will …

2016年10月6日 · "The molar mass of acetic acid is "60.05*g*mol^-1 And how did we get this quantity? All I did was take the molar mass of each element in the formula of acetic acid, weighted according to its frequency, i.e. "Molar mass" = {2xx12.011(C)+ 4xx1.00794(H)+2xx15.999(O)}*g*mol^-1 = 60.05*g*mol^-1. And can you tell me how many …

2016年6月24日 · According to the balanced chemical equation that describes the ionization of the acid, every mole of acetic acid that ionizes will produce. one mole of hydronium cations; one mole of acetate anions; If you take #x# to be the concentration of acetic acid that ionizes, you can find the equilibrium concentration of the hydronium cations by using ...

2017年5月2日 · Vinegar is an aqueous solution of "acetic acid....." And the formula of acetic acid is "H"_3"CC(=O)OH....." Typically this is obtained by oxidation of alcohol. Sometimes, when you don't finish off a bottle of wine (and this does happen sometimes), the next night you try it, the alcohol has turned into vinegar and is undrinkable.

2017年6月1日 · What are the products when calcium carbonate and acetic acid react? ... How can I know the formula of the ...
