Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
Answer:
Chlorine(Cl)
Explanation:
Because the shielding effect(by the inner electrons) remains the same but the nuclear charge is increasing(due to the increasing number of protons)
So Chlorine has the highest number of protons...so its outter electrons tend to expierence the most nuclear attraction hence making it more harder to remove the first electron
The correct option is B.
This question is testing your knowledge of the differences between solid and liquid particles. The particles of the solid vibrate around a fixed position, they can not move about while those of the liquid are able to move to some extent. The candy in Damien's pocket melted because it was heated up by the temperature of his body. Because the particles of the chocolate has been heated, they gain more kinetic energy and they vibrate faster compare to that of the solid chocolate.
