2. The beaker now contains sodium ethanoate, water and carbon dioxide. The temperature on the thermometer has fallen, meaning it is an endothermic reaction. When ammonium chloride powder is mixed ...

The equation shows that ammonium chloride (a white solid ... reaction takes place between anhydrous cobalt(II) chloride (which is blue) and water to produce hydrated cobalt(II) chloride (which ...

A white ring of solid ammonium chloride forms where the two gases meet inside the tube. If necessary, protect non-glass surfaces of an overhead projector with clear plastic. Dip one Q-tip into ...

The positive areas of the water molecules surround the negative Chloride ions. The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules ...

A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...
