The empirical formula of a molecule is the elemental composition whose subscripts (indicating number of atoms contained in the molecule) are the smallest positive integers that still describe the correct ratios of atoms. For example, HO is the empirical for...
Answer to: Determine the empirical formula of a molecule that is 18.02% carbon, 2.02% hydrogen, and 79.9% bromine. By signing up, you'll get...
19 Which formula represents a polar molecule?A:Cl_2B:HI 相关知识点: 试题来源: 解析 B: HI 该题考查分子极性。分子极性取决于原子电负性差异和分子结构。Cl_2 中两个氯原子电负性相同,分子结构为线性,电荷分布均匀,是非极性分子。HI 中碘原子电负性大于氢原子,导致分子中电荷分布不均匀,形成极性分子。因此,...
The meaning of FORMULA is a set form of words for use in a ceremony or ritual. How to use formula in a sentence.
the phenomena of fracture, crack and the like cannot occur, the glossiness of the plastic is high, the plastic makes demolding easy, the surface is prevented from being scratched due to high surface strength of the plastic; the demolding is easy due to good molecule fluidity; and the producti...
For ionic compounds, the smallest unit is the formula unit, which is the lowest whole number ration of the ions present. The molecule is the smallest part of a molecular compound that retains the chemical and physical properties of the compound. For an ionic compound, it is the formula unit...
If a compound is molecular, the molecular formula is preferred to the empirical formula since it gives more information. A molecule of glucose, for example, consists of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Its molecular formula, C6H12O6, displays this information explicitly; ...
What is an Empirical Formula? Learn the method to find the empirical formula with examples. Understand the way to find a molecular formula from an empirical formula. Understand how to find the empirical formula given the percent of mass composition of a molecule....
(Chemistry) a chemical formula showing the composition and structure of a molecule. The atoms are represented by symbols and the structure is indicated by showing the relative positions of the atoms in space and the bonds between them:H–C≡C–H is the structural formula of acetylene. See als...
What is the molecular formula for butane if it has an empirical formula of C2H5 and each molecule has 10 hydrogen atoms? Empirical Formulas: The empirical formula of a molecule is often different from its molecular formula. The molecular formula ...
