In this video, I demonstrate how to make an oxygen generator using manganese dioxide (MnO2) and hydrogen peroxide (H2O2) Alaska’s record snowfall sank boats and collapsed roofs Massive fraud ...

Scientists have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the ...

IN a recent communication in Nature 1, Dr. P. George described manometric experiments which showed a rapid initial decay of the enzyme compared with which the well-known decay due to irreversible ...

More efficient and sustainable energy conversion technologies, among other applications, hinge on lowering the amount of ...

With a new electrochemical synthesis via an electrochemical nitrogen reduction reaction (NRR), achieving carbon-free ammonia ...

It uses a system called simplified molecular-input line-entry system (SMILES). This translates chemical 3D structures into ...

New research shows that these fields speed up water dissociation not by lowering energy costs, but by increasing molecular disorder once ions form. The reaction becomes entropy-driven—exactly the ...

This page of IGN's Animal Crossing: New Horizons guide covers everything you need to know about Reactions, including how to unlock them all. Reactions are animations that are used to express yourself ...

To the first test-tube insert a glowing splint – record your observations. Repeat with the second test-tube of gas.

The same method is used as for carbon dioxide except zinc (or sometimes magnesium ribbon) is used in place of calcium carbonate. Collect 3 gas jars/test tubes of hydrogen gas in the same way.
