Answer:a series of an chemical reaction
Explanation:
Answer : 12 karat
Explanation : When pure gold is considered to be 24 karat then if its 50 mol% silver and 50 mol% silver then using karat scale calculation;
Karat/24 X 100 = 50 mol% (for gold) in alloy
So, Karat = (50 X 24) / 100 = 12 karat.
Hence the alloy will be of 12 karat.
True I believe because plants require gases which they take from the air.
There are other ions that make acidic and basic solutions, but we won't be talking about them here. That pH scale we talked about is actually a measure of the number of H + ions in a solution. If there are a lot of H + ions, the pH is very low.
Hope I helped :)
