Answer:

56.17% is percent composition of Sb in the molecule

Explanation:

Percent composition is the percent in mass of each element present in a particular molecule.

In SbF₅, there is 1 mole of Antimony -Molar mass: 121.76g- per 5 moles of fluorine -Molar mass: 19g/mol-. In a basis of 1 mole, the mass of Sb and F is:

<em>Mass Sb:</em>

1mol * (121.76g/mol) = 121.76g

<em>Mass F:</em>

1 mol SbF₅ = 5 moles F * (19g / mol) = 95g

<em>Total mass:</em>

121.76g + 95g = 216.76g

And percent composition of Sb:

121.76g / 216.76g * 100 =

<h3>56.17% is percent composition of Sb in the molecule</h3>

2) Which liberates the most energy?
evablogger [386]

Answer: F(g)+e^-\rightarrow F^-(g)

Explanation:

Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.  

The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.

F(g)+e^-\rightarrow F^-(g)

Which of the following statements is true?
dybincka [34]

Answer:C

Explanation:

A process is called spontaneous if the process takes place on its own without the intervention of external factors.

The spontaneous processes are generally quick with observable rates of reaction.But processes can be spontaneous even with negligible rates of reaction.

Spontaneity of reactions depend on temperature.

This is because spontaneity is measured by gibbs energy or enthalpy.

Both of these measures are dependent on temperature.

So,temperature affects spontaneity.
