Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
Explanation:
We have to calculate 
value.
It is known that at the equivalence point concentration of acid is equal to the concentration of anion formed.
Hence, [HA] = ![[A^{-}]](https://tex.z-dn.net/?f=%5BA%5E%7B-%7D%5D)
Now, relation between and pH is as follows.
pH = ![pK_{a} + log \frac{[A^{-}]}{[HA]}](https://tex.z-dn.net/?f=pK_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5BA%5E%7B-%7D%5D%7D%7B%5BHA%5D%7D)
Putting the values into the above formula as follows.
pH =
4.23 = 
(as [HA] = )
= 4.23 (as log (1) = 0)
or, = 4
Thus, we can conclude that of given weak acid is 4.
If element A has an ionic charge of +2 and element B has an ionic charge of -3
then the reaction is given as: A^2+ + B^3- --------------------> A3B2
the compound formed is : A3B<span>2</span>
At high speeds, there is more kinetic energy involved - more energy that will be converted to other forms of energy. This includes breaking a car, or body parts of people involved.
