You can think of pi bonds in the terms of pi electrons as well which will become more important in terms of aromaticity.
A Triple bond has 1 sigma bond & 2 pi bonds.
There are 6 electrons in a triple bond; 2 sigma electrons and 4 pi electrons.
The two unhybridized p orbitals on each atom on either side of the triple bond are perpendicular to each other. So, if you are trying to determine the number of pi electrons in an aromatic monocyclic compound and you have an uninterrupted combination of sp & sp2 orbitals (sp3 does not have p orbitals), whenever you come across a triple bond you would add 4 pi electrons and for a double bond you would add 2 pi electrons. The important thing to remember though is if the question asks for the number of electrons delocalized in the ring because of the aforementioned p orbitals in a triple bond being perpendicular only 2 of the 4 available pi electrons would delocalize in the ring. The really dirty trick is that Huckel's rule applies to electrons in the cloud, delocalized electrons.

There are two pi bonds in Cl2O. Each chlorine atom forms a double bond with the oxygen atom in the molecule.
How do you predict a sigma or pi bond?
Sigma bonds are always formed between two atoms when their atomic orbitals overlap head-on, resulting in the highest electron density along the bond axis. Pi bonds are formed when two parallel p-orbitals overlap side-by-side, resulting in electron density above and below the bond axis. You can predict the type of bond based on the orientation of the overlapping atomic orbitals.

How many sigma and pi bond are there in chlorine?
In a chlorine molecule (Cl2), there is one sigma bond and one pi bond. The sigma bond is formed by the head-on overlap of atomic orbitals, while the pi bond is formed by the sideways overlap of p orbitals.

It has one sigma bond and two pi bonds
What are the products of the hydrolysis of ATP what else is released during this reaction?
The products of the hydrolysis of ATP are ADP (adenosine diphosphate) and inorganic phosphate (Pi). In addition to ADP and Pi, energy in the form of a phosphate bond is also released during this reaction.
