This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)
10+17=17
Total amount is 32
32-17=15
15 is you mass
Hope this Helps
Alll are correct. Matter is literally everywhere
In the balanced reaction shown, there are twice as many moles of water as oxygen. If 13.35 moles of oxygen are reacted, 26.70 moles of water is formed.
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
Atomic number = amount of protons, so 7 protons.
Because it is a neutral atom, that means that the number of protons has to be the same as the number of electrons. So, there are 7 electrons.
The mass number of an atom, 15, is the total number of protons + neutrons, so 15 - 7 = 8. There are 8 neutrons
