Explanation:
Unlike the traditional definition of defining acid as any substance that can react with a base to form salt and water, there are two other definition of acid.
These are lewis acid and bronsted lowry acid.
Lewis acid is any substance that can accept a pair of non bonding electrons. This is why H+ is able to as a lewis acid.
Bronsted lowry definition on the other hand is as follows; A brosted lowry acid is any species that can donate a proton to another molecule. A bronsted lowry base is any specie that can accept a proton from another molecule. NH3 is able to accept a proton, hence it is termed as a bronsted lowry base.
BF3 act as a lewis acid because it can accept accept a pair of non bonding electrons. Generally; an atom, ion, or molecule with an incomplete octet of electrons can act as an Lewis acid.
Alloys are preferable at times because they offer interesting properties than pure metal. Alloys are made in order to modify or enhance properties, especially mechanical properties. Examples are stainless steel, brass and wrought iron.
Answer:
High rate of acceleration.
Explanation:
For an automobile power is meant by the power of engine i.e. the amount of energy the engine can deliver in a unit time to the powered-axle of an automobile. Practically it tells about the high throttle of the engine or the acceleration of the engine. This tells that in a very less time duration the car can attain high speed, also called pickup in the fancy term.
A) Combustion

Answer:
[H₃O⁺] → 0.063 M
Explanation:
To determine the pH, our formula is:
- log [H₃O⁺]
To determine the [H⁺] we have to apply the inverse function
10^-pH = [H₃O⁺]
10⁻¹'²⁰ = [H₃O⁺] → 0.063 M
