Mg gained mass because it went from being a single element (on the reactant side) to being a molecule (on the product side).
Answer:
A. 2
hope this helps :)
if you need an explanation let me know!!
<h2>Answer : Option C) Smaller volume - crowded particles - more collisions - high pressure</h2><h3>Explanation : </h3>
The kinetic molecular theory of gases explains that if there is small volume of gas there will be more crowding of the gas molecules inside the container. The crowded gas molecules will collide with each other and also with the walls of container as a result, exchange of energies will take place. Which will increase the pressure inside the container, and will raise the pressure than the initial pressure.
So this can explain the density of a person very clearly.
Bonjour,
increasing temperature.
for many solids dissolved in liquid water, the solubility increases with temperature.
