Represent the gravity of granite is 2.7
Answer:
Storage battery oe cell
Explanation:
The storage battery or cell is a device that coverts chemical energy into light energy when required.
During charging of battery, there is some chemical changes in the battery and absorb energy. The absorbed energy is converted into electrical energy when connected to an external load.
Hence, the correct answer is "Storage battery or cell".
Explanation:
As per Brønsted-Lowry concept of acids and bases, chemical species which donate proton are called Brønsted-Lowry acids.
The chemical species which accept proton are called Brønsted-Lowry base.
(a)
is Bronsted lowry acid and is its conjugate base.
is Bronsted lowry base and is its conjugate acid.
(b)
is Bronsted lowry base and HCN is its conjugate acid.
is Bronsted lowry acid and is its conjugate base.
(c)
is Bronsted lowry acid and is its conjugate base.
Cl^- is Bronsted lowry base and HCl is its conjugate acid.
(d)
is Bronsted lowry acid and is its conjugate base.
OH^- is Bronsted lowry base and is its conjugate acid.
(e)
is Bronsted lowry base and OH- is its conjugate acid.
is Bronsted lowry acid and OH- is its conjugate base.
Explanation:
Percentage ethylene by weight = 57%
Percentage propylene by weight = 43%
Suppose in 100 grams of polymer:
Mass of ethylene = 57 g
Mass of propylene = 43 g
Moles of ethylene =
Moles of propylene =
1 mole = molecules/ atoms
Units of ethylene =
Units of propylene =
a) Fraction of ethylene units:
b ) Fraction of propylene units:
The correct option would be 3.
Only thermal energy changes
