Soilds retain their shape because their particles (be they atoms or molecules) are locked in position by bonds or intermolecular forces of neighboring particles. When you heat a solid so that it changes phase to liquid form, the thermal energy put in serves to excite the particles of matter enough so that they are still held together but can now overcome the forces holding them rigidly in place and slides around each other. Liquids are virtually incompressible because the particles are still held together, but they can also flow and change shape because they're not fixed to the same arrangement.
Answer:
the mass of the copper piece is 110.2976 grams
- In chemical weathering minerals are changed into new minerals and mineral byproducts.
- Some minerals like halite and calcite may dissolve completely.
- Chemical weathering may change the size of pieces of rock materials, but definitely changes the composition.
- So one type of mineral changes into a different mineral.
- Chemical weathering works through chemical reactions that cause changes in the minerals.

Answer:
single replacement reaction
Explanation:
the iron molecules would rather react with Bromine instead of Iodine. So, the iron molecules switch over to bromine leaving the iodine molecules by themselves.
