Based on the equation, how many grams of Br2 are required to react completely with 72.4 grams of AlCl3 NEVERMIND, I FIGURED IT OUT

 131 g of bromine is required.

Explanation:

The balanced equation will be :

To calculate the moles, we use the equation:

moles of

According to stoichiometry :

2 moles of require  = 3 moles of

Thus 0.544 moles of require=  of

Mass of

Thus 131 g of bromine is required.

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.
