Can anyone help me with this?

(a)

--- Silicon

--- Tin

-- Lead

(b)

--- Silicon

--- Tin

--- Lead

Explanation:

Given

The attached table

Solving (a): The volume of each sample

For each element, the volume (v) is calculated as:

Where:

So, we have:

Silicon:

So, we have:

Tin:

So, we have:

Lead:

So, we have:

Solving (b): The density of each sample

For each element, the density (d) is calculated as:

Where

So, we have:

Silicon:

--- calculated in (a)

Density (d):

Tin:

--- calculated in (a)

Density (d):

Lead:

--- calculated in (a)

Density (d):

what does the table look like

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
