A decrease in the overall volume of gases namely hydrogen would prevent nuclear fusion in a nebula.
Answer:
involves the splitting of an atom into two or more fragments
Explanation:
The season that is starting is winter.
The answer to 21 is (4)
Liquid because 20 Celsius is 68 Fahrenheit<span />
Answer:
According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of
and keep same equilibrium constant
Explanation:
In this buffer following equilibrium exists -

So,
is involved in the above equilibrium.
When a strong base is added to this buffer, then concentration of
increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of
and keep same equilibrium constant.
Therefore excess amount of
combines with
to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
