Answer:
Atom: The smallest particle of an element that has the properties of the element and can exist either alone or in combination.
Particle: One of the very small parts of matter (as a molecule, atom, or electron)
Kinetic: Of or relating to the motions of material bodies and the forces and energy associated with them
Explanation:
Answer:
2Mg(s) + O₂(g) → 2MgO(s)
Explanation:
2Ca(s) + Cl₂(g) → CaCl₂(s) (incorrect)
Ca(s) + Cl₂(g) → CaCl₂(s) (correct)
Li(s) + Cl₂(g) → 2LiCl(s) (incorrect)
2Li(s) + Cl₂(g) → 2LiCl(s) (correct)
2C(s) + O₂(g) → CO₂(g) (incorrect)
C(s) + O₂(g) → CO₂(g) (correct)
Answer:
(not sure if this helps but)
The number of electrons in a neutral atom is equal to its proton.
Explanation:
The number of protons in a neutral atom are equal to its number of protons. It is also equal to its atomic number.
hope it helps :)
Answer:
A
Explanation:
The solubility of a substance is directly proportional to the temperature. It means that solubility will increase with the increases in temperature. At higher temperature, the kinetic energy increased that allow the solvent molecules to break the solute particles more effectively.
Substance A has a higher solubility because the weight of substance A measured at the end of the experiment is less than the weight of substance B.
Hence, the correct answer is A.
