What is the difference between the empirical and molecular formula of a compound?Can they ever be the same?Explain. 答案 (1)分子式是用元素符号表示物质(单质、化合物)分子的组成及分子量的化学式.而(2)最简式又叫实验式,它仅能表示化合物组成中各元素原子数目的比例.通常是以单独的元素符号来表示这类...
Based on the molecular formula, determine whether each of the following is an alkane, alkene, or alkyne. (Assume that the hydrocarbons are noncyclical and there is no more than one multiple bond.) a. Based on the molecular formula, determine whether each compound i...
Phenol is a common organic compound, also known as hydroxybenzene or phenol alcohol. Its chemical formula is C6H5OH, structural formula is C6H5-OH. Phenol is a white solid with a pungent odor and is readily soluble in water and many organic solvents.
What is the name of the molecular compound BF3? How to find molecular formula of a compound? What is the molecular formula for acetic acid? What is the molecular geometry of XeF4? What is the molecular structure of BrF5? What is styrene's molecular formula? What is isomerism in organic ...
A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indicat...
elemental or compound molecule. An elemental molecule contains only one type of atom, such asozone(O3) or chlorine (Cl2). A compound molecule is made up of one or more different elements. Covalent compounds are built on these types of molecules and are often referred to as molecular ...
IMC (Intermetallic Compound)is a chemical molecular. It’s not an alloy (note: some classify IMC as a type of alloy), nor is it pure metal. Since IMC is a molecular composition resulting from a chemical reaction (IMC can also form under ambient temperature through diffusion, but the proces...
In summary, the conversation discusses a problem involving an alkane and its molecular formula. The empirical formula of the alkane is C2H5, and the conversation goes on to explain how to determine the number of carbons and hydrogens in the molecule using this information. ...
An ionic compound is formed by the reaction of a metal with a non-metal, whereas a molecular compound is usually formed by the reaction of two or more non-metals. In ionic compounds, the ions are held together due to electrical attraction, whereas, in molecular compounds, the atoms are he...
Molecular hydrogen (H2) contains two atoms of the same element of hydrogen. Since H2 contains two or more elements, but the elements are not different, molecular hydrogen is a molecule. Sodium hydride (NaH) is made up of two different elements, sodium and hydrogen, so NaH is a compound. ...
