What is the number placed in front of a chemical formula that tells how many atoms or molecules there are in the formula?
it's a subscript
How many magnesium atoms would be needed to react with one bromine molecule?
Two magnesium atoms.
How many niobium atoms would have to be laid side by side to span a distance of 4.76 mm?
Depending on the material used (atoms laid down side to side or raw metal in a grid) will also depend the specing between the atoms. http://en.wikipedia.org/wiki/Atomic_radius When laid out in a grid of 145pm, in the 4.76mm line there would be 4.76E-3 / 145E-12 = 32827586 atoms. Since the outer layer of metal atoms is formed by valence band electrons, you coudl easily stretch or compress the required amount of Nb atoms.
How many atoms would 3 moles of Ca have?
3 moles of Ca would have 1.806 × 10^24 atoms.
The diameter of an helium atom is 100 pico meters how many helium atoms must be placed end to end to make chain of helium atoms one centimeters long?
100 million helium atoms, being the number (1.0E-2 m)/(100E-12 m).
What are the differences among atoms?
the crystal structure, its emission spectrum, and how many and where it's electrons are placed in the atoms shell
How many atoms do you need to equal the distance of one meter?
There are so many atoms in a meter that it would be impossible to count them all perfectly. It is also necessary to know what atom you where talking about if you possibly want a "good" answer.
How many hydrogen atoms does caffeine has?
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
How many atoms must be placed end-to-end to make a chain of atoms one-millionth meter long?
An atom is about 10-11 meter in diameter, so to make a chain of them 10-6 meter long you would need about 10-6/10-11 =105 or 100,000 atoms.
