Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...
The comb is sterilized chemically (for example, by ethylene oxide at 60 °C). The adherence and proliferation activity of bacteria is monitored in two distinct procedures. We confirmed the nature ...
They were exposed to a stream of ethylene gas flowing into a reaction chamber while being introduced to tungsten oxide on silica, which resulted in the breakage of the carbon-carbon bonds.

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...
Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. A catalyst is a substance that speeds up a chemical reaction.
This creates hydrogen to feed into the ethylene reaction but also oxygen that the gallium nitride absorbs to become gallium nitride oxide. The copper is good at hanging onto the hydrogen and ...
