Another significant characteristic of side effects is that side effects are mild in nature and self-resolving when compared to adverse effects. What is an Adverse Effect In the medical field, an adverse effect is a harmful, undesirable effect that that result from a medication or other intervention such as surgery.
A synthesis reaction is the joining together of two reactants (compounds) to produce a complex product (compound). Sometimes synthesis reactions can result in the formation of more than one product, as we will see shortly with the process of photosynthesis.
In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product is another way to identify a synthesis reaction. For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance-----water! The chemical equation for this synthesis reaction looks like: reactant + reactant -------> product.
