Answer:
PH₃.
Explanation:
Hello.
In this case, among the options:
PH₃, GaF₃, SF₂ and CO₂
We compute their molar masses by adding the atomic masses of the constituting elements by their subscripts:
Thus, the answer is PH₃.
Best regards.
The answer is A. The “plums” or the “raisins” of the pudding are the electrons. The actual “pudding” is the nucleus, which is made up of protons and neutrons, so it is a large positively charged mass.
Hope this helps!!! ^v^

The answer is volume, in gasses, volume depends on the matter, but in solids, volume can be measured.
The electron group arrangement of PH₃ is tetrahedral. The molecular shape is a Trigonal pyramid, and the bond angle is 93°.
<h3>What is the bond angle?</h3>
The angle between the atoms in a compound is known as the bond angle. The degree of the binding angle is specified. There is also the bond length. It is the separation between the two atoms' nuclei.
The bond angle between the atoms of phosphine is 93°. It has one lone pair. The central atom is covered with 4 atoms.
Thus, the electron-group arrangement of phosphine is tetrahedral. The molecular geometry or shape is a trigonal pyramid. The bond angle is 93°.
