Question

For a science fair project about food and chemistry, Bill looks around his kitchen for examples of covalent compounds. What evidence can Bill use in his project to show that water (H2O) acts like other covalent compounds?

Answer 1

B) He can demonstrate that water can be boiled on a simple kitchen stove.

Step-by-step explanation:

Answer 2

Answer: by freezing a pure water and allowing it to melt.

Step-by-step explanation:

Covalent compounds generally have low boiling and melting points and are found in all three physical states at room temperature.

At temperature 0°C or 32°F pure water ice melts and changes state from a solid to a liquid.

This is an evidence that water have a very low melting point as to other covalent compounds like CaO, MgO.
