Explanation:
avogadros law states that under constant temp n pressure, volume of a gas is directly proportional to amount of gas
amount of gas1 = 352millimoles
amount of gas2 = 352+100 = 452millimoles
new vol = old vol x 452/352 = 25.2 x 452/352
= 32.4 mL

Explanation:
<span>If one chooses to blow carbon dioxide gas into aqueous barium hydroxide it will reduce. This happens because the ions become removed from the solution and in turn this decreases the conductivity of it.</span>
Physical Properties<span>: </span>Physical properties<span> can be observed or measured without changing the composition of matter. </span>Physical properties<span> are used to observe and describe matter. so physical changes are the change in temperature of the land and the evaporation of water and change humidity of the air. chemical change is the ripening of the orange</span>
