Acompound consists of 4.50 g of nitrogen for every 7.71 g of oxygen and has the same empirical and molecular formula identify the compound

Explanation:

Hi, the empirical formula is the minimal expression of the molecule composition and doesn't always represent the molecule in the reality.

On the other hand the molecular formula is a multiple of the empirical and represents how the molecule is composed in reality.

In this case they are the same.

Now, nitrogen has an atomic weight of 14 g/mol and oxygen one of 16 g/mol:

So the formula would be:

Dividing per 0.321:

In natural numbers:

if you're asking what comes out, it's steam.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
