Carry out these steps, and record your findings in the table. 1. Pour water to the 2.0 mL mark in the graduated cylinder. If you look at the graduated cylinder from the side, you will see the water forms a curve. Make sure the bottom of the curve is at the 2.0 mL mark. 2. Use the gram scale to measure the mass of the graduated cylinder and 2.0 mL of water. Record the mass in the table. Calculate the mass of 2.0 mL of water by subtracting the mass of the graduated cylinder. 3. Repeat this process to find and record the mass of 4.0 mL of water and then 6.0 mL of water. 4. Density is mass in grams divided by volume in cubic centimeters (cm). 1 mL is equal to 1 cm. Calculate and record the density of water.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
