What Have individual monomers known as nucleotides?
its is mulecules
How do you find the mass and volume of a atom?
it depends on how many mulecules it contains ^_^
How do food molecule glucose benefits life?
how food mulecules from glucose benefit life
Why is the speed of sound slower then the speed of light?
The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.
If helium and oxygen have the same number of mulecules the same distance apart what makes helium lighter?
Helium is less dense than oxygen because it has a smaller atomic mass (4 amu compared to 16 amu).
What can cause snow to melt?
As snow or any form of frozen water heats up the mulecules absorbe the heat as internal kinetic energy. This causes the molecules, which are locked in place by attractions to other molecules while 'cold' enough, to move faster and faster until they can break free from their positions in the solid. With enough energy absorbed all the molecules are free to move out of the position in the solid and flow around each other. There are still attractive forces which keep the molecules close together in liquid form. This is what we call melting.
Pure substances that are made up of more than one element is called?
Matter that has more than one type of atom is called a compound. Examples of compounds include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl). The elements in a compound are chemically bonded either by covalent bonding, which involves the sharing of electrons, or by the formation of ionic bonds, which occurs when one atom loses an electron and becomes a positively charged ion, and the other atom gains the electron and becomes a negatively charged ion. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
How do the particles behave in the reaction between iron and sulphur?
The iron atoms absorb enough energy to lose three electrons each and become iron(III) ions. The octa-atomic sulphur molecules absorb enough energy to become sulphur atoms. These atoms each gain two electrons to become sulphide ions with a -2 charge each. Since electrons are conserved, 1½ times as many sulphur atoms so react as do iron atoms. These ions now form a solid and give up energy. The overall process gives up energy (enough so that some of the solid goes off as a smoke).Depending on how far you are in chemistry, you could get by with this explanation, or you could discuss whether the iron(III) sulphide formed is a simple ionic solid as described or something a bit more complicated.
What happens to a sample of water when it is heated between 4 degrees c and 100 degrees c?
4 degrees celcius is the temperature at which water has it's highest density. As it goes lower towards freezing, it actually expands (one of waters most interesting and important attributes)As you heat water from 4 degrees celcius, it gradually looses it's density, and steadily comes closer to crossing the threshold of boiling.Fun fact:Why is it that the bathroom is full of steam after i've showered, when the water wasn't nearly hot enough to be turning in to it's gas form (which it is generally concieved that water mulecules do once they reach 100 degrees celcius, and boiling starts)?This is because energy in the mass of water as a whole, is not distributed evenly between the molecules.As a consequence, some water will vaporize, even though most of the water still is far from doing so.So to answer the rest of the question: as the water gradually rises in temperature, more and more water will have the nessecairy energy to vaporize.And so, at some point, the vapor pressure of the liquid, is equal to the pressure exerted on it by the surrounding environmental pressure, and at that point, the water starts boiling.
