Answer:
pH = 2.18
Explanation:
Perchloric acid (HClO₄) is a strong acid. This means that in an aqueous solution it completely dissociates into H⁺ and ClO₄⁻ species.
First we <u>convert 249 mg HClO₄ into moles</u>, using its <em>molecular weight</em>:
- 249 mg HClO₄ ÷ 100.46 mg/mmol = 2.49 mmol HClO₄
<em>Because it is a strong acid</em>, 2.49 mmol HClO₄ = 2.49 mmol H⁺
We <u>calculate the molar concentration of H⁺</u>:
- 2.49 mmol H⁺ / 380 mL = 6.52x10⁻³ M
Finally we <u>calculate the pH of the solution</u>:
- pH = -log[H⁺] = -log(6.52x10⁻³)
Answer:
Because the Earth is always shifting, so research has to constantly be updated.
<span>Which determines whether the fire will have open flames?
flash point - this is not the answer as it only denotes the minimum temperature required for vapors of something combustible will ignite
exothermic energy - is the energy released during the combustion reaction so this is not the answer
type of fuel - is not the general answer
The answer is </span>fuel-air mix as it will determine the vigor of the flame.
Answer is: Proteins-growth and repair of cellular structures.
Proteins are macromolecules made of amino acids (usually 20 amino acids) and they are main structure molecules of all living cells.
Lipids and sugars (glucose) are main source of energy in every living organism and they are used as the cell's energy reserves.
