Answer:
the atomic number is 11 and element is Sodium (Na)
Explanation:
Number of Protons = Number of Electrons = 11
Number of Neutrons = 13
Here, the Number of Protons and Number of Electrons is 11
So,
the atomic number is <em><u>11</u></em> and element is <em><u>Sodium </u></em><em><u>(</u></em><em><u>Na) </u></em>
Answer:
1) 17.5 mL
Explanation:
Hello,
In this case, the reaction between sulfuric acid and potassium hydroxide is:

In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:

And in terms of concentrations and volumes:

Thus, we solve for the volume of acid:

Best regards.
