Answer:- Third option is correct, relative strength of orange juice to pure water is 1000 times
Solution:- pH is a way to represents the strength of the acids. Lower is the pH higher is the acid strength and higher is the pH lower is the acid strength. So, we could say that acid strength is inversely proportional to the pH.
From given pH value, we calculate the hydrogen ion concentration and then compare the hydrogen ion concentrations of the two acids to find out the relative strength.
for orange juice = and for pure water it is .
So, the relative acidity of orange juice compared to pure water =
= 1000
So, third option is correct, the relative strength of orange juice to pure water is 1000 times.
Answer:
Closed as it can never be an open system for a number of reasons.
Answer:
You find the molar mass of calcium metal, it is listed as 40.1⋅g⋅mol−1 . You should check your copy of the Periodic Table to see if I have got it right. This means that Avogadro's number of calcium atoms, i.e. 6.022×1023 individual calcium atoms have a mass of 40.1⋅g .
Explanation:
The second thesis statement is perfect. It supports the claim and presents main idea.
