Answer:
The correct answer is "A buffer resists pH change by neutralizing added acids and bases".
Explanation:
In chemistry, a buffer is defined as an aquoeous solution that resist pH changes. Buffers are comprised of a weak acid (HA) and its conjugate base (A−) in an equilibrium relation, which results in the buffer neutralizing added acids and bases. Buffers play a crucial role in living beings since they provide a relative stable environment for the cells in what is known as homeostasis.
Answer:
On returning to lowest energy state which is stable, it releases energy in the form of light. Hence, option A that is the electron releases energy in the form of light on falling to lower energy state from excite state.
Out of the available answers, the most likely correct would be that
eventually everyone must sleep due to our need for mental rest. However,
it is not as simple as this, as all of the processes implicated with
mental rest (including the restoration of biological rhythms as
mentioned in an alternative answer) cannot necessarily be summed up in
this way.
Answer:
Destiny = 5 g/ml
Explanation:
The formula for density is d=
Knowing this, divide your mass by volume:
10 g / 2 ml = 5 g/ml
Final answer:
Destiny = 5 g/ml
