Elements, Mixtures and Compounds. Chemistry is the study of physical matter, which is classified in many different ways, such as state of matter (gas, liquid or solid), chemical form (element, mixture or compound), chemical structure (atoms or molecules, etc.) and so on. In animal cells, cytokinesis results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus. In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells. Mitosis animation (480 k) OR The elements on top of the column will replace the elements below them on the periodic table but not the other way around. Thus, the reaction represented by.

Again, the formula for copper was simply Cu but became CuO, CuCO 3, CuSO 4, and various other compounds due to chemical change. Sometimes there is no obvious change to a formula, but bonds within the substance are broken and the substance takes on a different shape which doesn't reverse back to its original shape. That is also a chemical reaction.
