Write ONLY ONE Net ionic equation for each of the following reactions. Give state only for solids, weakly dissociated or gases. No state is required for aqueous solutions. Rules sufficient for judgment which salts are soluble or insoluble: All Na , K and NO3 - salts are well soluble. Please do any preparative work on a scratch paper, so that only ONE equation will be placed in the space highlighted in yellow. Start writing in the position of the arrow to be within yellow space.

During metamorphic processes, increased pressure and temperature can affect the of minerals in rock. rocks subjected to very high pressure are typically than others because mineral grains are squeezed together, and the atoms are more closely packed. during metamorphic processes, water facilitates the transfer of ions between and within minerals, which can the rate at which metamorphic reactions take place. the growth of new minerals within a rock during metamorphism has been estimated to be about per million years. metamorphism is commonly associated with convergent plate boundaries, where two plates move toward each other. during contact metamorphism, a large intrusion will contain thermal energy and will cool much more slowly than a small one. metamorphosed sandstone is known as the metamorphic rock made from metamorphosed shale, was once used to make blackboards for classrooms.
