describe the difference between a monoprotic acid and a triprotic acid. How does a triprotic acid generate hydrogen ions?
natita [175]
With the Bronsted-Lowry theory of acids and bases, acids donate protons to other substances. A monoprotic acid is an an acid that can only supply one proton (hydrogen). A triprotic acid is an an acid that can supply up to three protons (hydrogens). A triprotic acid get get its hydrogen ions by receiving them from a base.

For the reaction of hydrogen with iodine
fenix001 [56]

Answer:

r_{H_2} = \frac{-1}{2} r_{HI}

Explanation:

Hello!

In this case, considering the given chemical reaction:

H_2(g) + I_2(g) \rightarrow 2HI(g)

Thus, by applying the law of rate proportions, we can write:

\frac{1}{-1} r_{H_2} = \frac{1}{-1}r_{i_2} = \frac{1}{2} r_{HI}

Whereas the stoichiometric coefficients of reactants are negative due their disappearance and that of the product is positive due to its appearance. In such a way, when we relate the rate of disappearance of hydrogen gas to the rate of formation of hydrogen iodide, we obtain:

r_{H_2} = \frac{-1}{2} r_{HI}

Best regards!

What is the octet rule? What is it based on?
Nimfa-mama [501]

Answer: The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
