NEED HELP ASAP What type of reaction is shown in this image AND what is the result of this reaction?

I can't understand the picture, it could be synthesis or decomposition.

Explanation:

If they are added togethere then write synthesis and if one element is broken to two the it's decomposition.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
