Second, take notes on Cell Respiration. Last week, we said the following 3 statements about how we know Photosynthesis is a chemical reaction: Products are different than the reactants. Atoms are rearranged into new molecules. Endothermic reaction because it absorbs energy. Direct current is a bit easier to understand than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current. DC can be generated in a number of ways: An AC generator equipped with a device called a "commutator" can produce direct current. Use of a device called a "rectifier" that converts AC to DC. A chemical reaction must occur to separate a compound into its different atoms/elements. Unlike mixtures, which have no fixed ratios of elements (it’s not even!), compounds are created from the combination of atoms in specific proportions (like in H 2 O, there is a ratio of two atoms of hydrogen to every oxygen molecule). I would point out next time that during the reaction, the bottle gets warm and steam is produced from the water, because this is an exothermic (heat-producing) reaction. I would also mention that although a catalyst speeds up a chemical reaction, it is left unchanged itself: the dissolved yeast is left in the bottle. The Book and the Hat-Tip
