Answer:
Explanation:
Hello!
In this case, we consider the given reaction to realize there is a 5:4 mole ratio between oxygen and nitrogen monoxide; thus, we infer that, at STP conditions, such mole ratio is eligible as a volume ratio too; therefore, the produced liters of nitrogen monoxide gas is:
Best regards!
In the compound Co2O3, cobalt has an oxidation number of 3, while oxygen's oxidation number is -2.
An oxidation number is a number assigned to an element in chemical combination that represents the number of electrons lost (or gained, if the number is negative) by an atom of that element in the compound.
The answer to the problem is 7/10
Finding the difference in math usually means to subtract to numbers. In the case of your problem though, I think the correct answer would just be 4...
Answer:
²³⁵₉₂U
Explanation:
The right symbol for the nuclei is ²³⁵₉₂U;
For this chemical element, the atom is represented by the symbol U;
To the superscript before the symbol is the mass number
The subscript before the symbol is the atomic number
Mass number is the number of protons and neutrons
Atomic number is the number of protons.
