Hello, I need help studying for a chemistry test out could someone please help get the baseline down for some of these prompts so I have a template to expand off of. 1.Using experimental data, determine the relative mass of two objects

2.Use experimental data to determine the number of particles in a sample without counting them individually

3. Given a chemical formula, determine its molar mass be able to calculate mass, mole, or number of particles from any one of mass, mole, or number of particles.

4. Given a chemical formula, be able to calculate the percent composition for that substance.

5. Given percent composition data, be able to calculate the empirical formula for a substance.

6. Given percent composition data and molar mass, be able to determine the molecular formula for a substance.

Explanation:

false

because it does not have the potential to be entirely used up

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.
