A. 1
b. 1
c. 1
d. 4
As u can see H is the only one with 4 atoms as in the chemical formula it has a little 4 next to it
He conditions needed to produce lightning have been known for some time. However, exactly how lightning forms has never been verified so there is room for debate.
Leading theories focus around separation of electric charge and generation of an electric field within a thunderstorm. Recent studies also indicate that ice, hail, and semi-frozen water drops known as graupel are essential to lightning development. Storms that fail to produce large quantities of ice usually fail to produce lightning.
Hope this helps!
Answer: The molarity of the solution is 2.00 M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L = 1.00 L
moles of solute =
Thus the molarity of the solution is 2.00 M
Answer:
True
Explanation:
It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.
1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.
2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.
The values of pH and pOH always obey the following expression:
pH + pOH = 14
Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.
For example, in an acidic medium:
if pH= 3, pOH= 11
In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.
