Answer:
George Washington is the first president
Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)

Hence, The pH of a solution containing 0.1 mM H+ is 4
Answer: C6H12O6+6O2→6CO2+6H2O+energy C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + energy .
Explanation:
Answer:
It contains only about an eighth of our sun's mass. Faint red Proxima Centauri is only 3,100 Kelvin (5,100 degrees F or 2,800 C) in contrast to 5,778 K for our sun. So Proxima is 500 times less bright than our sun.
