Answer:
+2
Explanation:
Nickel (II) oxide, or NiO, is an ionic compound. Recalling a few rules of determining the oxidation number of substances:
1. Oxidation numbers of elements in ionic compounds are usually their own ionic charge
2. The total oxidation number of a neutral compound should be 0
And,
3. The oxidation number of oxygen in most cases is -2.
Therefore, since O in NiO has a oxidation number of -2, and nickel (II) ion usually has a charge of 2+, the oxidation number of Ni in NiO is +2 (always remember to put the positive sign in front of the number)
Answer:
Explanation:
Calcium sulfide is the chemical compound with the formula CaS.
I would convert my years of age to months, to days, to hours to minutes and finally to seconds. By knowing these facts:
365 days = 1 years
1 day = 24 hours
1 hour = 60 minutes
1 minute = seconds
I would be able to solve it.
Answer: What are phase fractionation methods used for? well They apply to the prefractionation of the sample to obtain less complex protein mixtures for an easier analysis; they are also used as a means to evidence specific proteins or protein classes otherwise impossible to detect.
Explanation: in spanish /
Se aplican al prefraccionamiento de la muestra para obtener mezclas de proteínas menos complejas para un análisis más fácil; también se utilizan como un medio para evidenciar proteínas específicas o clases de proteínas que de otro modo serían imposibles de detectar.
