Define inference and explain how it is used to form conclusions

What will happen to the temperature of a substance if the kinetic energy of the molecules decreases?

Justin added concentrated HCl solution in excess to 45.8 grams of magnesium metal and collected the hydrogen gas that was produced by the reaction. Mg (s) + 2 HCl (aq) → MgCl2 (aq) + H2 (g) If Justin collected 2.

Water (h20) is composed of the same element as hydrogen peroxide (h202) how do their properties compare? They have different properties because the arrangement of atoms is different. They have the same properties because they have the same atoms.
