Answer:
Melting Is when a substance is actually melting and melting point is a point at which a substance is able to melt.
First, we must know that the hydronium ion is formed when a water molecule accepts a hydrogen ion. Therefore, the hydronium ion concentration is equivalent to the hydrogen ion concentration. Furthermore, the equation relating pH and hydrogen ion concentration is:
pH = -log[H+]
4.33 = -log[H+]
[H+] = 4.68 x 10⁻⁵ M
The concentration of hydronium ions is 4.68 x 10⁻⁵ M
Answer:
When you know the number of moles that you expect, you will multiply by the molar mass of the product to find the theoretical yield in grams. example, the molar mass of CO2 is about 44 g/mol. (Carbon's molar mass is ~12 g/mol and oxygen's is ~16 g/mol, so the total is 12 + 16 + 16 = 44.)Explanation:
Oxidation numbers are the electrical charges of ions. Transition metals, such as manganese, can have multiple oxidation states. We can use the oxidation states of other elements in the compound with manganese to determine manganese's oxidation state.
