Hydrogen does everything that it's possible to do in the universe when given enough time. Hydrogen is the lightest and simplest atom, and so it was the most common element to form after the universe cooled sufficiently to contain matter. Eventually, hydrogen formed vast clouds and the first stars.
These early stars were the nuclear furnaces that forged the heavier elements in the universe. As the first stars died, they scattered these elements into space to fuel the next generation of stars along with the first planets and everything on them. Eventually, some of those heavier elements formed organic molecules and began to evolve into life. Hydrogen, left to itself for several billion years, creates galaxies.Learn More
Substances that are attracted to water molecules are known as hydrophilic molecules. These molecules can interact on a molecular level with water and are also known as water soluble molecules.Full Answer >
Octane has a density of about 0.703 grams per cubic centimeter when evaluated at standard temperature and pressure conditions. At these conditions, the temperature is equal to 32 degrees Fahrenheit and 100 pascals of pressure.Full Answer >
Nitrogen is dangerous to consume in its liquid form. While the chemical is non-toxic, its extreme cold temperature, which ranges as low as -346 degrees Fahrenheit, has the ability to cause significant injury or death.Full Answer >
The molecular weight of myoglobin depends on what organism's myoglobin is being used. For calibration in mass spectrometry, horse myoglobin and sperm whale myoglobin are the most common. Horse myoglobin has a molecular weight of 16,951.49, and the myoglobin from sperm whales has a molecular weight of 17,199.91.Full Answer >
