If the acid is 100 percent dissociated in solutions of 1.0 M or less, it is called strong. Sulfuric acid is considered strong only in its first dissociation step; 100 percent dissociation isn't true as solutions become more concentrated.
Answer:
is the limiting reagent
Explanation:
To calculate the moles :


The balanced chemical reaction is :
According to stoichiometry :
1 moles of
require = 2 moles of 
Thus 0.625 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent as it is present more than the required amount.
Maximum number of electrons in nth energy level

Now
Max electrons


I think the answer is it turnes into a gas. Hope it helps! :) Asnwer is density.
Explanation:
In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
So, when at 298 K and 1 atm
exists in liquid state and
exists as a gas then it means there occurs strong force of attraction between the molecules of
due to which it exists in liquid form.
Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among
molecules are greater than those among
molecules.
