A new study has found that up to half of people who think they have a penicillin "allergy" can still receive the drug, and other antibiotics with similar structures, without any negative reactions to the meds. Why? Because they're not really allergic, doctors say.
In this video we learn how to understand chemical change in Chemistry. When you start out, you must first figure out what your cathode and anode is in the equation. Then, read it out to find out if it's oxidized. Once you have this figured out, you can find the conditions of temperature you need to maintain the chemicals. You can figure this out b doing a basic equation for all of the chemicals. Fill this in with the correct information, then the answer will be done. Make sure you understand ...
