Hi.
From the knowledge I have left of biology, I have to go with D. Decomposers
Hope this helps!
I think the correct answer is 109.5 degrees. The bond angle of a chlorite ion or ClO2- ion is 109.5 and has a bent shape. This is because of two groups of bonding electrons and two lone pairs of electrons. Another example of a molecule that has a bent molecular geometry is water. It results from its tetrahedral electron pair shape.
The answer is A. The pH decreases
D. Viral disease
Because it’s a virus that spreads around to other people and need a vaccine to combat it
