The particles move faster when more thermal energy is added creating heat.
Answer:
Explanation:
1. the 1/2 reaction that occurs at the cathode
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
2 the 1/2 reaction that occurs at the anode
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
E0 = -0.59v
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
E0 = 1.39v
3Cl2 (g) + 2MnO2 (s) + 8OH^(−) (aq)---------> 6Cl^(−) (aq) + 2MnO4^(−) (aq) + 4H2O (l)
E0cell = 0.80v
Answer: A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!! :D
Answer:
Mass of Oxygen = 32 grams
Explanation:
Given:
Mass of water = 36 grams
Mass of Hydrogen = 4 grams
Find:
Mass of Oxygen
Computation:
Using Law of Conservation of mass
Mass of water = Mass of Hydrogen + Mass of Oxygen
36 grams = 4 grams + Mass of Oxygen
Mass of Oxygen = 32 grams
When an atom of the unstable isotope Na-24 decays, it becomes an atom of Mg-24 because the Na-24 atom spontaneously releases (2) a<span> beta particle</span>.
