    Pre-Lab Work Sheet Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down‚ ionic bonds have high melting and boiling points. In covalent bonds‚ the intermolecular forces are very weak and

    Homeostatic Mechanism using the Comparitive Melting-Point Method for two Crab Species. Abstract Two crab species‚ Plagusia and Cyclograpsus‚ were collected from a local estuary in the littoral and deep water zone for osmoregulation studies. To examine differences in osmoregulatory mechanisms among the species‚ haemolymph of the specimens was extracted once they were acclimated to varying concentrations of seawater. Using the comparative melting-point‚ capillary tubes were filled with small samples
