There are conformational and constitutional isomers that are differentiated based on their composition.Answer and Explanation: Constitutional isomers are molecules with molecular formula composition, but they h
How is water a molecule and a compound? In what ways are hydrogen bonds and ionic bonds similar? When two hydrogen atoms chemically bond to one oxygen atom, what do they create? What attracts the atoms in an ionic bond? A polar covalent bond is created when ...
First, there are two electron pairs on the molecule, which means there will be a large partial charge vector in that direction. Next, oxygen is more electronegative than hydrogen and will hog the electrons. This means that the partial charge vector on each bond will have a component pointing ...
For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...

They break down into a gooey, messy blob because the liquid in the hydrogel evaporates too quickly for the substance to retain its shape. With each molecule that seeps out, others try to fill the gaps. This causes what's known as capillary stress within the pores of the gel, causing the...
What will be the molecular formula of a compound with vapour density 15 and empirical formula CH2O? AC2H4O2 BC6H12O12 CCH2O DC6H6OSubmit Assertion: Molecular formula shows the exact number of different types of atoms present in a molecule of a compound. Reason : Molecular formula can be ob...
smallest particle in a chemical element or compound, they are made up of atoms that are fused together by chemical bonds that form when electrons share or exchange among atoms. Now, researchers have reached new heights and managed to build a molecule for the very first time in scientific ...
Topoisomerases are classified into several families, namely, types IA, IB, IC, IIA and IIB. These families have different cellular roles and preferential substrate specificities. Topoisomerases are involved in a range of cellular nucleic acid transactions, including DNA replication, transcription, packag...
How is water a molecule and a compound? What is the difference between an element and a compound? What are the characteristics of chemical elements? How can two different nonmetals form a compound? What does each different element on the periodic table of elements represent? How are synthetic...
