thermometer
stopwatch
graduated cylinder

Explanation:

• A ruler is used to measure lengths, so it is appropriate for measuring the sides of a metal cube.
• An electronic balance is used to measure mass. Sodium chloride and silver nitrate are measured by mass, so an electronic balance is the right tool.
• A graduated cylinder is used to measure the volume of liquids. Water is a liquid, and 15.0 mL is a volume measurement, so a graduated cylinder is correct.
• A thermometer is used to measure temperature. Mark needs to measure the temperature change of a solution, so a thermometer is the required tool.

Answer:

ruler, electronic balance, graduated cylinder, thermometer
