[H₃O⁺]=4.4 x 10⁻⁴
pH=3.357
[OH⁻] = 2.28 x 10⁻¹¹
<h3>Further explanation</h3>
Given
HNO3 concentration = 0.00044 M
Required
[H3O+],[OH-] and the pH
Solution
HNO₃ = strong acid
HNO₃ ⇒ H₃O⁺ + NO₃⁻
[H₃O⁺]=[HNO₃]=4.4 x 10⁻⁴
For strong acid pH=-log[H₃O⁺]
pH=-log 4.4 x 10⁻⁴ = 4-log 4.4 =3.357
pOH+pH=pKw
pOH+3.357=14
pOH=14-3.357=10.643
pOH=-log[OH⁻]
<span>The main purpose of an antacid is to reduce acidity and thus ph will increase inside the stomach. Thus, by the consumption of an antacid, the pf of of the urine will decrease and it will become acidic.</span>
Answer:
Ionic bonds hold atoms together using the electrostatic charge between their positive and negative ions. These ions are formed when electrons are transferred between atoms, the net loss or gain determining if the ion is positive, called a cation, or negative, an anion.
Explanation:
A solar panel works by talking in light and transforming it into energy and a windmill collects kinetic energy to transform it into energy.
A) They are different states of matter.
