Estimate the mass of oxygen in this building. Explain the bonding in benzene. How do glow sticks work? How do the double bonds in a hydrocarbon affect its solubility? How do you make aspirin? How many isomers of XXX can you draw? How many moles of water are there in this bottle of w...
The emission of absorbed energy as light as the result of a chemical reaction. This occurs in thousands of compounds both organic and inorganic. Chemical glow sticks and fireflies are examples of this.Coefficient of linear thermal expansion The ratio of change in length per degree centigrade compar...
initially emitting infrared, then red, orange, yellow, and white light as it becomes increasingly hotter. When the temperature of a firework is controlled, the glow of components, such as charcoal, can be manipulated to be the desired color (temperature) at the proper time. Metals, such...
With our Glow Lab, Vortex Lab and Fire Lab, we provide everything you need to explore the wonders of chemistry. Fire Lab Activities: The Fire Lab helps kids learn about combustion, oxidation capillary action and other concepts. Here’s a list of activities and experiments that come with the...
As I was growing up, my curious nature often led me to wonder why leaves turn orange and red in the autumn or what makes glow sticks glow? It fascinates me that the genetic makeup of humans and other species is down to four base molecules held together by hydrogen bonds. Current global...

Serial macromolecular crystallography has become a powerful method to reveal room temperature structures of biological macromolecules and perform time-resolved studies. ID29, a flagship beamline of the ESRF 4th generation synchrotron, is the first synchr
