Hi teacher,How does the sand help in absorb the heat/ prevent it from cracking the glass?Sodium in group 1 and reacts with water. But in this experiment, does the water act as a catalyst?How come the sodium cannot react without addition of water?
2Na(s) + Cl2(g) → 2NaCl(s)teacher, macam mana sand to absorb heat and glass tu tak pecah?kenapa sodium tak react? kenapa kena ada addittion of water?kalau sodium + chlorine(liquid) what will happen?
