When a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid forms and the iron dissolves, some of the water ...
This is because dextrose only has one molecule, so there’s no chain for the body to break down. Longer chain molecules, such as proteins, take longer to be broken down by the body and as a result, don’t cause the blood sugar to spike in the way that single molecules like dextrose ...
An acid is a molecule that donates what? What is common to all acids? Is HBr a strong acid? What is the strength of the hydrohalic acids from weakest to strongest (HF, HCl, HBr, HAt)? What is hydrochloric acid made of? Explain two ways that strong acids can be differentiated from ...
blood will be drawn from the vein in your arm and siphoned into a special tube for laboratory testing. The blood is tested for hemoglobin levels in the red blood cells, which can help your doctor if you have anaemia caused by iron deficiency. Iron produces the molecule heme, which carries...
Antidiuretic hormone (ADH) is a hormone secreted by the hypothalamus which plays a significant role in regulating fluid and electrolyte balance in the body. This hormone directly affects the blood volume, the level of water in the body, the concentration ...
Water and the bad smelling molecule hydrogen sulphide do not seem to have a lot in common at first sight. However, when investing a little energy, some differences disappear. At first glance, the ice cube in your soft drink and the smell of grandma’s famous egg salad don’t seem ...
The hydrogen ion does not remain a free proton for long, as it is quickly hydrated by a surrounding un-ionized water molecule. The formation of the resulting ion, the hydronium ion, is represented in equation [2]: [2] H2O + H+⇔ H3O+ ...
Betaine anhydrous is a molecule that comes from the breakdown of choline, and you can find it in sugar beets, wheat germ, quinoa, spinach and other foods. In humans, betaine is essential for methylation, a metabolic process that’s behind the synthesis of creatine (24). Much like electroly...
Different substances have different constants because each molecule has a different "natural elasticity," which allows some to store vastly greater amounts of energy than others. Among frequently used dielectrics are plastics of various kinds, air, mica, and paper. ...
Define an electrolyte. Define electrolyte and non-electrolyte. What is the definition of a strong electrolyte? Give some examples. Is CaI2 classified as a strong electrolyte? Explain. What does it mean to describe the charge distribution of a molecule?
