M₁=50 g
m₀=60 g
w=100m₁/m₀
w=100*50/60=83.3%
Answer:
<u>Reasons water is important </u>
Imagine earth without water. The soil, with no water in it and nothing growing on it, would be lifeless, dead, collapsed into dust, sand, clay or rock.
-Water consumption helps lubricate and cushion your joints, spinal cord, and tissues. This will help you enjoy physical activity and lessen discomfort caused by conditions like arthritis.
-Water is a main component of saliva. Saliva also includes small amounts of electrolytes, mucus, and enzymes. It’s essential for breaking down solid food and keeping your mouth healthy.
It would be D light dependent reaction, I don’t have much of a explanation but I promise it’s D
Answer: Ozone's molecular geometry can be described as bent.
Explanation:
The molecular geometry of the O3 groups has a trigonal planar arrangement.
Here is a quick explanation of the molecular geometry of O3 including a quick description of the O3 bond angles.
Examining the Lewis structure of O3 we can see that there are a pair of unbounded valence electrons at the top of the structure.
Based on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) these electrons will repel the electron clouds of the two oxygen atoms on the end.
As a result they will be pushed down giving the 03 molecule a bent molecular geometry or shape.
The 03 bond angle will be 116° degrees since it has a Bent molecular geometry
