Answer 1

To identify elements in the salts YX and ZX, use the boiling point elevation data and the van't Hoff factor to calculate the molar mass of each compound. This information will help deduce the identities of elements Y and Z when compared with known elements.

Step-by-step explanation:

Finding the Identity of Elements in a Salt through Boiling Point Elevation

Regarding the question about using the boiling point elevation to identify elements in salts YX and ZX, we can use colligative properties formulas to find the molar mass of the unknown compounds. Given the van't Hoff factor (i), boiling point elevation (ΔTb), mass of the salt (m), and the solvent's mass (kg), we can use the formula ΔTb = i * Kb * m/molar mass. Using the provided boiling point elevation data, we can calculate the molar mass and then infer the identities of elements X, Y, and Z by comparing the computed molar mass with known elements.

For YX: A 0.20°C boiling point elevation is detected when 5.82 g of the salt is dissolved in 100.0 g of water. With the van't Hoff factor of 2, you can find the molar mass of YX and identify element Y.

For ZX: A 0.30°C boiling point elevation is observed when 7.09 g of the salt is dissolved in 200.0 g of water. Similarly, using the van't Hoff factor of 2 for ZX, you can calculate the molar mass of ZX and identify element Z.
