Answer:
False
Explanation: isotopes generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Setting up the equation, you get


Therefore, the equation is 
The correct answer is C - sound.
Sound is a wave, and it is thus not considered a form of matter.
Answer:
CaF2 + CO3- ----> CaCO3 + 2 F-
Explanation:
The chemical compounds found on the left side of the date are the reagents and those found on the right are the products, where calcium carbonate appears.
Calcium carbonate is a quaternary salt
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
