Curious about reduction & oxidation? In this two-part episode of The Science Catalyst hosted by Barry Lambson, the subject of Chemistry, reduction & oxidation is gone over with iron powder and copper sulphate. Oxidation and reduction are heavily related which is why they are both considered "redox reactions". Acids and bases may be thought of as reactions involving hydrogen, or protons, while redox reactions tend to be concerned with electron gain and loss.

During pregnancy the natural curves of the spine become exaggerated causing the lower back to sway as well as the upper back and shoulders to round. This rolling forward of the shoulders causes the ribcage to collapse down compressing the lungs and diaphragm which results in a breathless feeling along with feeling like there is very little space left for the baby. Another unfortunate result of the ribcage compressing the stomach area is the stomach acid gets pushed up the esophagus resulting ...

Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
Having a Clostridium difficile infection means stomach pains, diarrhea, fever, and loss of appetite, and if the symptoms weren't bad enough, the disease often reoccurs. Now, new research has found an increased risk of recurrence in people who take medication to treat their stomach acid, gastroesophageal reflux disease, peptic ulcer disease, or stomach discomfort.
Having someone send you flowers will almost always lift your spirits. Wilting, dying flowers, on the other hand, aren't so great to look at and smell even worse. While there are time-honored tricks to keep flowers alive longer (change the water regularly, put a penny in the bottom of the vase, and cut stems diagonally are three that come to mind), it turns out that a few items in your kitchen are pretty useful at making sure those blooms stay perky.
Is it possible to cut or chop onions in the kitchen without stinging eyes and looking as if you just watched the saddest movie ever? Before we get to that answer, it's important to know why we tear up when cutting raw onions in the first place. What is this irritant? Are you reacting to the odor? The answer to the latter question is "no," and the irritant responsible is amino acid sulfoxides.

In this tutorial, we learn how to solder with a soldering iron. You will need: tinning pads, desoldering braid, and an adding component. Start off by heating the copper, before you add the wire. You need for the acid to flow from the core onto the copper to create a surface that will accept the solder. A cold solder will break or cause burn. If you use too much solder, use the braid to remove it. Next, place the wires onto the holes and heat them onto the circuits where you want them to be pl...
