C. If the banks of the river are eroding, then the river will be wider.
im pretty sure its A if i did all my reasearch right.
hope this helps luv. <3
Answer:
Hybridization: sp
Electron geometry: linear
Molecular geometry: linear
Explanation:
H₃CCCH can also be written as its Lewis structure which is shown in the figure attached. The figure shows that the central carbon atom makes a single bond with CH₃ and a triple bond with CH. This means that the hybridization of the carbon is sp and both the electron and molecular geometry are linear with an 180° bond angle.
C. C and Pb; Carbon and Lead being in the same group.
