A student created the following model to show how the salt cesium sulfate would appear when added to water. Water particles were not included in the student’s model for simplicity. Did the student model the salt dissociation correctly ? Support your claim with evidence from the model.

State two physical properties of ionic compound

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Calculate the temperature rise when 0.2g of propane is used to heat 400cm cubed of water.
