Una muestra de 3,87 mg de ácido ascórbico (vitamina C) por combustión genera 5,80 mg de CO2 y 1,58 mg de H2O, el ácido ascórbico contiene solamente C, H y O. ¿Cuál es la composición en porciento de este compuesto (el porcentaje de masa de cada elemento), y cuál es la fórmula molecular?

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
