Answer: Yes the formula of the compound formed is $Fe_2S_3$

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

If iron is having an oxidation state of +3 called as $Fe^{3+}$ cation. Sulphur is an anion with oxidation state of -2 and forms sulphide ion $S^{2-}$ . Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $Fe_2S_3$ .

The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.

Determine how much energy is needed to change 50 g of liquid water at 100°C to steam.

marin [14]

Answer:

$Q=113,000J$

Explanation:

Hello there!

In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:

$Q=m*\Delta _{vap}H$

Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.

$Q=50*2259.36 J/g\\\\Q=113,000J$

Which is positive due to the necessity of heat.

Regards!

State the definition of the partial molar Gibbs energy.

balu736 [363]

Explanation :

As we know that the Gibbs free energy is not only function of temperature and pressure but also amount of each substance in the system.

$G=G(T,P,n_1,n_2)$

where,

$n_1\text{ and }n_2$ is the amount of component 1 and 2 in the system.

Partial molar Gibbs free energy : The partial derivative of Gibbs free energy with respect to amount of component (i) of a mixture when other variable $(T,P,n_j)$ are kept constant are known as partial molar Gibbs free energy of $i^{th}$ component.
