<u>Step 1: Define</u>
Water H₂O
<u>Step 2: Find Formulas Mass</u>
<em>Formula mass is molar mass.</em>
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
Answer:
C. hydrocyanic acid
Explanation:
The mixture of a weak acid (As hydrocyanic acid, HCN), with its conjugate base (Na⁺CN⁻) produce a buffer effect in the solution due the equilibrium:
HCN ⇄ CN⁻ + H⁺
Now, when NaOH (A base) is added to the mixture, the reaction with <em>HCN </em>is:
NaOH + HCN → Na⁺CN⁻ + H₂O
As the OH⁻ of NaOH are not affecting directly the H⁺ concentration, <em>the pH does not increase dratically.</em>
<em />
Right answer is:
<em>C. hydrocyanic acid
</em>
Well protons and neutrons are in the center in the atom, while electrons travel in orbitals outside of the nucleus. The electric charge for protons, neutrons, and electrons are 1, 0, and -1 respectively. the mass for protons and neutrons are 1 amu (atomic mass unit) while the electron is 1/2000 amu.<span>
