This is a simple chemical change due to what it produces and how it is added together. Hope this helps.
B) The elements become less reactive.
Answer:
Electron pair geometry- trigonal planar
There is one lone pair around the boron atom
The geometry of BH2 is bent
Explanation:
The valence shell electron pair repulsion theory offers a frame work for determining the shape of molecules based on the number of electron pairs of the valence shell of the central atom in the molecule.
In BH2-, the central atom is boron. There is a lone pair on boron. Owing to the lone pair on boron, the molecular geometry of BH2 is bent.
A control group is the group in an experiment that does not receive any sort of change, to then be compared to the other treated objects at the end of the study.
