Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

Today's super-resolution microscopes have made it possible to observe the nanoscale world with unprecedented detail. However, ...

because no chemical bonds are broken or formed as it takes place. But it generates heat, so can be described as exothermic. Although aqueous solutions of 'slaked' lime are alkaline, its solubility ...

DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the ...

Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally ...
