I have checked wikipedia it says the IUPAC name is Sodium pentacyanonitrosylferrate(II). But according to me its Sodium pentacyanonitrosylferrate(III).

Na2[Fe(CN)5NO]

Oxidation number calculation

-2= x + (-5) + 0 => x= 5-2= 3

So the oxidation number of Fe should be 3.

Shouldn't the oxidation number be 3? What is the correct IUPAC name? Please explain.

ron metal is produced in a blast furnace by the reaction of iron (III) oxide and coke (pure carbon). If 25.0 moles of pure Fe2O3 is used, how many grams of iron can be produced?

Two glass vessels M and N are connected by a closed valve.
MN
M contains helium at 20 °C at a pressure of 1 × 105 Pa. N has been evacuated, and has three times the volume of M. In an experiment, the valve is opened and the temperature of the whole apparatus is raised to 100 °C.
What is the final pressure in the system?

A student performed an experiment to measure the enthalpy change of combustion of ethane.
He used the following values for the standard enthalpy changes of combustion of carbon and hydrogen.
carbon = –394 kJ mol–1 hydrogen = –286 kJ mol–1
He calculated the enthalpy change of formation of ethane to be –140 kJ mol–1.
What was his experimental value for the standard enthalpy change of combustion of ethane?
