thermometer my friend since it is a measureful device
thanx
heyaaaa
Your answer is C - Melting of a substance
Answer:
Explanation:
Hello,
In this case, given the acid, we can suppose a simple dissociation as:
Which occurs in aqueous phase, therefore, the law of mass action is written by:
That in terms of the change due to the reaction's extent we can write:
But we prefer to compute the Kb due to its exceptional weakness:
Next, the acid dissociation in the presence of the base we have:
Whose solution is which equals the concentration of hydroxyl in the solution, thus we compute the pOH:
Finally, since the maximum scale is 14, we can compute the pH by knowing the pOH:

Answer: controller.
Justification:
A fission reaction is the split of the nucleus of an atom due to the bombardment with neutrons.
A fission reaction may terminate in a reaction chain, a controlled reaction or extinguish.
When for every 2 or 3 neutrons released, only one neutron is allowed to strike a fissionable nucleus, the reaction is controlled.
When the the ratio is less than one then the reaction will be extinguished.
When the number of reactions grow, this is a reaction chain, where the reaction is out of control, and the consequence is the release of vast amount of energy (heat) is a short time, causing a nuclear explosion.
