What is the oxidation number of the oxygen atom in H2O2? Is hydrogen reactive? What is the number of electrons in the outermost energy level of an oxygen atom? What is the dominant species of cobalt? What elements does lawrencium react with?
What happens when methane reacts with oxygen? View Solution What will happen when sodium reacts with cold water? View Solution What happens when silver nitrate reacts with sodium chromate? View Solution When water is dropped over sodium peroxide, the colourless gas produced is ...
A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). For many years, we’ve used natural gas to heat our homes and...
To understand what happens when chlorine reacts with slaked lime, we can break down the process step by step:Step 1: Identify the Reactants - Slaked Lime: This is chemically known as calcium hydroxide (Ca(OH)
Living things, for example, are mostly made from the atoms carbon, hydrogen, and oxygen. These are just three of over 100 chemical elements that scientists have discovered. Other elements include metals such as copper, tin, iron and gold, and gases like hydrogen and helium. You can make ...
Astrocytes help clear neurotransmitter chemicals so that the synapse can be ready to react to the next signal that might arrive. Oligodendrocytes produce and maintain the myelin sheath that coats and insulates the axon, making electrical conduction more efficient. ...
Magnesium atoms react with oxygen to form Magnesium oxide. 5 Magnesium Ion It is positively charged due to an imbalance between protons and electrons. The positive charge of the Magnesium ion plays a role in ionic bonding. 6 Common Curiosities What's the difference between a Magnesium Atom and...
Carbon, hydrogen, and oxygen are present in air and water. Water may contain a variety of elements according to your local treatment plant additions and should be factored into your final conductivity factor. Rain water should have an EC of 0.0. ...
As thunderfvck said, it is electrons being excited by the energy released during the violent reaction with oxygen or fusion in the sun. This energy can then be converted into motion = heat or photons = light. May 30, 2004 #7 loseyourname Staff Emeritus Gold Member 1,829 5 I ...
