How many atoms are in one mole of carbon?Mole:A mole is a unit to count atoms or molecules. When we have a mole, we are counting one Avogadro's worth {eq}\displaystyle (N_A = 6.022\ \times\ 10^{23}){/eq} of these atoms or molecules. The mole is an important quantity because...
How do we turn that into something much more useful, namely electricity? A nuclear power plant works pretty much like a conventional power plant, but it produces heat energy from atoms rather than by burning coal, oil, gas, or another fuel. The heat it produces is used to boil water to...
carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a
First, water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another, so they clump together in big droplets on the window. The forces that make them do this are called cohesive forces (and the process involved is called cohesion). Second, ...
Making a photocopy requires a light source with enough energy to boot electrons out of the photoconductive atoms. What wavelengths of light can do this? It turns out that most of the visible spectrum of light contains enough energy to drive the process, especially the green and blue end of ...
carbon atoms form tightly bonded carbon crystals that are aligned more or less parallel to the long axis of the fiber. In some processes, two furnaces operating at two different temperatures are used to control the rate of de-heating during the carbonization phase....
When the gas is hot enough, the compound molecules break apart, and the atoms recombine with the oxygen to form water, carbon dioxide and other products. The gases, which rise through the air, make up the flame. Carbon atoms rising in the flame emit light as they heat up. (Check out ...
Then, through a process similar to a neon sign, they collide with the atoms and molecules of Earth’s atmosphere to create the light we call the aurora. Not all solar storms produce aurora. Only if the solar storm’s magnetic field couples with Earth’s magnetic field do we have a ...
Gravity influences many physical processes on the blue planet we call home. For example, gravity alters the way that atoms come together to form crystals. Aboard the ISS, experimenters can develop bigger and better-structured crystals than they could on Earth. Such crystals could help us devise ...
but perfect for igniting in an engine. It mixes with air to create a combustible mixture that gets your car going. To get molecular, gasoline is made up of a mixture of hydrogen and carbon atoms. The composition depends on the refining process and the original source. Producers may include...
