Answer : The concentration is, 0.0316 M
Explanation :
pH : It is defined as the negative logarithm of hydrogen ion concentration.
First we have to calculate the pOH.
Now we have to calculate the concentration.
Therefore, the concentration is, 0.0316 M
At STP, the volume of Cl2 is 22.4 L/mol.
11.5 L Cl2 * (1 mol Cl2/ 22.4 L Cl2)= 115/224 mol Cl2.
115/224 mol Cl2* (70.90 g Cl2/ 1 mol Cl2)= 36.4 g Cl2.
The final answer is 36.4 g Cl2.

Answer:
d. the relative age of these rock layers
Explanation:
Principle of superposition -
It is the form of relative dating , where the relative age of the rocks are determined .
It is on of the important principle for the study of geological stratigraphy .
According to the principle of superposition , the bottom most layer of the strata is one of the oldest one , and the top most is the most recent one .
Hence , the relative age of the rock can easily be determined by using this principle of superposition .
The answer is B, large turbines
The location of an electron can't be determined exactly, because of it's high speed, by the time we define it in a position, it changes it position. The location is determined by probability, and also uncertainty theory
