Answer:
Explanation:
When we react Hydrochlorid Acid with zinc we have the following reaction:
2HCl(aq) + Zn(s) --> ZnCl2(aq) + H2(g)
The hydrogen gas formed is lost to the environment, so we can affirme that in the start we have the mass for all the H, Cl and Zn atoms in the solution, but after the reaction occurs, we have only the mass for the Cl and Zn atoms.
That's why the mass is less than the original.
The law that the student was told is only applied to closed environments.
Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.
