2 answers:
Answer:
b. a proton donor.
Explanation:
An acid can be defined as a substance that produces hydrogen ions or H+ protons when dissolved in water, according to Arrhenius
It, also, can be defined as a molecule or ion which gives or donates a H+ protons when dissolved in water, according to Bronsted y Lowry
And, finally, according to Lewis, an acid can be defined as any compound that can accept a pair of electrons.

Answer : The balanced chemical equation is,
Explanation :
Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on product side.
The given unbalanced chemical reaction is,
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of individual elements are not balanced.
In order to balanced the chemical reaction, the coefficient 2 is put before the , the coefficient 3 is put before the
and the coefficient 4 is put before the
.
The energy evolved in this reaction =
Thus, the balanced chemical reaction will be,
The balanced chemical reaction is :
Number of moles of Na, .
Now, from balance chemical reaction we can see that 1 mole of oxygen reacts with 4 moles of sodium.
So, number of moles of oxygen are :
So, amount of oxygen required is :
Therefore, 5.08 gram of oxygen will react with 14.6 gram of sodium.
