3 days ago · Alcohols are classed as tertiary alcohols when the hydroxy group is bonded to a carbon atom that is, in turn, attached to zero hydrogen atoms and three alkyl groups. Tertiary alcohols can be described with the R C O H 3 general formula where R is an alkyl group.
4 days ago · Number of atoms = (mass of the sample / molar mass) × Avogadro’s number. First, divide the mass of your sample by the molar mass of the element or compound. Then, multiply the result by Avogadro’s number, which is 6.022×10²³. This formula helps you determine how many individual atoms are present in a given amount of substance.

3 days ago · K-ion batteries (KIBs) have drawn much attention due to the abundant potassium reserves and wide accessibility as well as high energy density, which can be designed for large-scale energy storage systems. As the most promising anode materials for KIBs, graphitic carbons, especially those with an intermediate structure between the crystalline graphite and amorphous carbons become a hot research ...
5 days ago · But carbon has 4 electrons in the valence shell. It can neither lose electrons nor it can gain electrons and hence, it shares electrons. So, covalent compounds can be formed by carbon atoms. Example: Methane. Carbon has 4 valence electrons and hydrogen has 1 electron.
