El número de oxidación de un elemento se refiere a la carga que posee un átomo cuando se encuentra como ion. Determina cuál es el número de oxidación del azufre, S, en los siguientes compuestos: H2S​

What is an example of a physical property?

Consider the elements bromine and chlorine; which elements has a larger ionic radius ?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
