In order to answer this question, the units of volume must be consistent. In this problem, we decide the unit m3 to be uniform. Option A is equal to 12 m3, option b is equal to 1.2x10^8/100^3 or 120 m3. Option C is 2.0 x10^4/ 10^3 or 20 m3. Option D is 1.2x10^8/ 1000^3 or 0.12 m3. The greatest volume is option b. 120 m3.
Okay thanks for the update I will give you a call when you get home thanks
Answers to wave questions:
1) trough - lowest point of the wave.
2) crest - highest point of wave.
3) amplitude - distance from rest position to the crest or thoughs.
4) wavelenght - distance from two consecutive crest or troughs.
5) rest position - the flat line running through middle of the wave.
In the reactants Sb has oxidatin number 0 (because it is in its elemental form)
In the products Sb has oxidaton number +3.
Then Sb lost electrons which means it oxidized.
Explanation:
hypothetically speaking it's becouse the charges will either could have been lost or not thus since the electron drifted away from the nucleus its energy increases.
