substrate
The symbol (g) is gas (in a chemical reaction) or gram.
In a battery, there is a cathode, that gives off electrons in a chemical reaction, and an annode, which absorbs electrons in a complimentary chemical reaction. A car battery uses lead (which I will call by its chemical symbol Pb) as the cathode, and lead oxide (PbO) as the annode, both of which are bathed in Sulphuric acid. Lead is oxidized by water in the reaction Pb + H2O = PbO + 2H+ + 2e- (the symbol H+ stands for a hydrogen ion, and e- stands for electrons). The reaction at the annode is PbO + 2H+ + 2e- = Pb + H2O This regenerates the lead, making the car battery rechargable. The Sulphuric acid is a source of H+ which is used to get the reaction going at the annode (the cathode reaction is also a source of H+, but the reaction at the annode requires a large amount of H+ to get going) so Sulphuric acid can be considered a catalyst for this reaction.
The delta symbol in a chemical equation stands for "change". Since you have to break and reform the bonds between atoms in molecules to have a chemical reaction there is going to be a change, whether it be in the thermal energy, chemical energy, phase of the matter etc.
The chemical symbol Pb stands for "lead", Plum bum.
The HVZ Reaction is an organic reaction and stands for the Hell-Volhard-Zelinsky halogenation reaction. It involves replacing an alpha-hydrogen with a halogen.
in the enzymatically controlled chemical reaction a to b plus c, the letter a stands for what?
The symbol (g) is gas (in a chemical reaction) or gram.
PCR stands for Polymerase Chain Reaction.
K stands for the chemical pottasium.

It is butane.
PKR can stand for a lot of things. In entertainment it stands for a poker website. In relation to Science and technology it could be referring to a Pauson-Khand reaction or a chemical reaction. It could also stand for People's Justice Party, a political party found in Malaysia.
SiO2 is the chemical formula (not symbol) of silicon dioxide.
Mg stands for magnesium and O stands for oxygen, on the chemical reaction of both the following happens in the presence of heat: Mg + O ---> MgO magnesium + oxygen = magnesium oxide
