The Law of Conservation of Mass states that during a chemical reaction, mass/matter is not Because of this law, there must be exactly the same number and kind of on each side of a chemical equation. To check if an enantion is balanced or not simply count the number of atoms of each element on the reactant side of the equation and check to see if there are the same number of atoms of each element on the ___side of the equation. If so, it is balanced.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
