Explanation:
A compound or molecule which will have least dissociation and that is not able to given hydrogen ion easily upon dissociation will also have a low value of
.
Dissociation of the given compounds or species will be as follows.



As, chemical formula of bicarbonate is
and due to the presence of a negative charge it is difficult to lose a positively charged hydrogen ion. This is because oppositely charged ions will be bonded by strong force of attraction.
Hence, it will not easily lose a hydrogen ion due to which bicarbonate has the lowest
.
Thus, we can conclude that out of the given species bicarbonate has the lowest
.
To satisfy the law of conservation of mass
Please note that since magnesium is in group 2 it has a valency of 2+ and so the formula for magnesium hydroxide is

This is a typical neutralization reaction of an acid with a base to form a salt and water. The reaction is exothermic, gives off heat,

, and may be balanced by adding balancing numbers in front, ie adding molecules, in order to ensure that the total number of atoms of each element is the same on the left and right hand sides of the equation.
Doing so we obtain :

Explanation:
to identify an atom you need to know either it's atomic number or it's proton number
while the neutron is used to determine it's atomic mass
Answer:

Explanation:
Hello there!
In this case, according to the given information, it possible for us to realize that this problem is solved via the ideal gas equation:

By which we solve for n (moles) as shown below:

Then, we plug in the given pressure, volume and temperature (in K) to obtain:
