It would most likely be acid rain
To find moles from grams would be the amount of grams which in your case is 3.4 divided by the molar mass which is just adding ip Si, O2
should be nonpolar covalent bond i believe, the electronegativity is the same
<u>Answer:</u> 0.943 M of potassium hydroxide solution is required.
<u>Explanation:</u>
A neutralization reaction is defined as the reaction in which an acid reacts with a base to form a salt and water molecule.
To calculate the molarity of potassium hydroxide, the equation used is:
........(1)
where,
are the n-factor, molarity and volume of acid that is
are the n-factor, molarity and volume of the base that is KOH
We are given:
Putting values in equation 1, we get:
Hence, 0.943 M of potassium hydroxide solution is required.
Answer:
ka = 2x10⁻⁹
Explanation:
Using the pH we can <u>calculate the molar concentration of H⁺</u>, [H⁺]
- = [H⁺] = 2.24 x 10⁻⁵ M
Then we use the expression of Ka for the equilibrium of a weak monoprotic acid:
HA ↔ H⁺ + A⁻
Where:
ka =
ka = = 2x10⁻⁹
