Standard temperature is 273 K
Standard pressure is 1 atm
We use the ideal gas equation to find out density of nitrogen gas in g/L
Ideal gas equation:
Molar mass of 
Pressure = 1 atm
Temperature = 273 K
= 1.25 g/L
Therefore, density of nitrogen gas at STP is 1.25 g/L
A sodium atom contains 11 protons and 12 neutrons. Also A sodium atom contains 11 protons, so its atomic number is 11
For every 3 Fe there is only 1 Fe3O4 producing.
So, ratio would be: Fe3O4 / Fe = 1 / 3
In short, Your Answer would be: 1 : 3
Hope this helps!
Answer:
In a redox reaction, hypochlorite ion would be more easily reduced.
Explanation:
Hypochlorite compounds are generally unstable - e.g. sodium hypochlorite is not available in solid form, because removing water from a NaClO disolution, causes a dismutation, turning it in a mixture of NaCl y NaClO3. Heating the same disolutions will also cause this effect. Hypochlorite will decompose under solar light into chlorides and oxygen.
Due to their low stability, hypochlorite compounds (i.e. those containing the hypochlorite ion) are very strong oxidants. Perchlorate ion can balance its negative charge instead and thus will be less prone to reduction than hypochlorite.
