Answer: The pair that consists of a base and its conjugate acid in that order.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms which is a conjugate acid.
Answer:
The correct statement should be The energies of electron are <em>quantized</em> when <em>they are bounded to an atom.</em>
In Quantum Mechanics The term Quantization used to measure the physical entities having certain discrete value. When we say energies of electron are <em>quantized</em> <em>that means it have some specific values</em> that are allowed, that is not continuous range of values.

Kcal=1000 cal
Min=60 sec
0.74 *1000= 740cal/min
740 cal/min /60= 12.333 cal/s
Speed (m/s) = distance (metres) ÷ time (seconds)
For Track 1: 0.2 ÷ 2 = 0.1m/s
For Track 2: 0.2 ÷ 2 = 0.1m/s
For Track 3: 0.6 ÷ 6 = 0.1m/s
For Track 4: 0.4 ÷ 6 = 0.07m/s
The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.
