pH scale is used to determine the acidity of a solution
pH is calculated using the H⁺ concentration
pOH scale is used to determine how basic a solution is
pOH is calculated using the OH⁻ concentration
pH and pOH are related in the following formula
pH + pOH = 14
pH = 3
pOH = 14 - 3
pOH = 11
pOH is calculated using the following formula
pOH = - log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = antilog(-11)
[OH⁻] = 1 x 10⁻¹¹ M
the [OH⁻] concentration of lemon juince is D) 1 x 10⁻¹¹ M
Incomplete combustion (where an element or compound reacts with oxygen to produce carbon monoxide and water) as a result of too little oxygen being available such that complete combustion(in which the first product is carbon dioxide instead) is not possible.
A covalent bond is a bond between 2 non metals, they share electrons. Ionic bonding occurs between a metal and a non-metal, and they transfer electrons.
Answer:
potassium and fluorine both react and form potassium fluoride.
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General reaction:
A + B → AB
For example in given potassium and fluorine reaction both react and form potassium fluoride.
Chemical reaction:
K + F₂ → KF
Balanced chemical reaction:
2K + F₂ → 2KF
The oxidation state of potassium is +1 while the oxidation state of fluorine is -1. That's why one atom of potassium combine with one atom fluorine and form potassium fluoride.
