The pH can be obtained directly from the concentration using the formula below pH = - log [H⁺] Hence, pH of a 8.4x10⁻⁶ M H⁺ solution is 5.08.
<h3>
What is pH ?</h3>
A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
Taking the negative logarithm of the concentration of hydronium ions that are in the solution:
pH = - log [H⁺]
= - log [8.4x10⁻⁶ ]
= 5.08
Hence, pH of a 8.4x10⁻⁶ M H⁺ solution is 5.08.

Answer: true
Explanation:
All living things need food to provide materials for growth. ... A food chain typically only has a few steps (usually 4 at the most). This is because each time one organism eats another, some of that energy is used up and released as heat.
Answer:
2.268
Explanation:
5 lb × 0.45359237
= 2.26796185 kg
How to convert Pounds to Kilograms
1 pound (lb) is equal to 0.45359237 kilograms (kg).
1 lb = 0.45359237 kg
The mass m in kilograms (kg) is equal to the mass m in pounds (lb) times 0.45359237:
m(kg) = m(lb) × 0.45359237
Example
Convert 5 lb to kilograms:
m(kg) = 5 lb × 0.45359237 = 2.268 kg
Hope this helped!!!
I believe the answer is <span>In an instant the car comes to a complete stop.
The net force is calculated through:
F = m x a
m = mass
a = Acceleration
When the car came into a complete stop, the acceleration become 0
Which means that
F = m x a
F = m x 0
F= 0 </span>
The mechanism for the reaction of the alkene side product with concentrated hydrochloric acid cannot easily abstract proton to form alkene.
We do not observe alkene side product because Cl- (chloride) is a poor base which cannot easily abstract proton to form alkene.
For obtaining alkene as product, Sulphuric acid H₂SO₄ is used.
Hydrochloric acid, additionally called muriatic acid, is an aqueous answer of hydrogen chloride. it is a drab solution with a specific pungent smell. Hydrochloric acid, additionally known as muriatic acid, is an aqueous solution of hydrogen chloride. Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (quick-term) inhalation publicity may also purpose eye, nostril, and breathing tract irritation and infection and pulmonary edema in humans.
A reaction mechanism is the collection of standard steps with the aid of which a chemical response occurs. A reaction that occurs in or greater elementary steps is known as a multistep or complex response. A response intermediate is a chemical species that is fashioned in a single essential step and ate up in a subsequent step.
