2 answers:

7 0

The statement that would beat describe an Arrhenius acid would be the second Option. It produces H+ ions in solution. The other definitions would be suitable for Arrhenius base, Bronsted Lowry Acid/Base, and Lewis Base.

Answer: it produces $H^+$ in solution

Explanation:-

According to Arrhenius concept, an acid is defined as a substance which donates hydrogen ions $(H^+)$ in water and a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Arrhenius acid: $HCl\rightarrow H^++Cl^-$

Arrhenius base: $NaOH\rightarrow Na^++OH^-$

If element x forms the oxides xo and x2o3 the oxidation numbers of element x are

Deffense [45]

Answer:

b) +2 and +3.

Explanation:

Hello,

In this case, given the molecular formulas:

$XO$

And:

$X_2O_3$

We can relate the subscripts with the oxidation states by knowing that they are crossed when the compound is formed, for that reason, we notice that oxygen oxidation state should be -2 for both cases and the oxidation state of X in the first formula must be +2 since both X and O has one as their subscript as they were simplified:

$X^{+2}O^{-2}$

Moreover, for the second case the oxidation state of X should be +3 in order to obtain 3 as the subscript of oxygen:

$X_2^{+3}O_3^{-2}$

Thus, answer is b)+2 and +3

Best regards.
