HON CHEMISTRY: So the little mole turns out to be a pretty big deal – and a very handy tool!!
Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!

Today’s latest inventions include the creation of a micro heart monitor that takes the first steps down the road of wearing ultrasound patches. These patches record how sound waves bounce off of each other. This helps doctors examine organ damage, diagnose internal diseases, or track bacteria.
Scientist have recently invented a new way to brush your teeth by using nano particles. The nano particles are very small magnetic balls, when bristles are attached to the nano particles they are able to moved around to brush your teeth.
Chemistry Nobel prize winners have found a way to snap together compounds easily, which eventually combine. They are able to catalyze the reaction without copper, which harms living cells. This helps scientist be able to snap together complex molecules.

Scientists have wanted to see if they could possibly redirect an asteroid’s path if one were to pose a threat to us in the future. NASA has finally tested this tactic on an asteroid named dimorphos. NASA’s DART not only succeeded in hitting the asteroid, but it decreased the asteroid’s revolution time by a whole 32 minutes around the larger asteroid that it orbits. https://www.snexplores.org/article/nasas-dart-spacecraft-successfully-bumped-an-asteroid-onto-a-new-path
Recently scientist have discovered that your phone can determine the stability of a bridge. Scientists are using information gathered by the phone such as vibrations to determine whether the bridge may need repair.

Harlequin frogs is a genus of frogs consisting of around 100 species. In the 1980’s a skin eating fungus wiped out about 1/3 of these frog species. Ever since this mass extinction, people have been constantly searching for traces of these frogs. I’m the past few years, there have been a few rediscoveries of once-extinct species of harlequin frogs.
