If your new bike is painted so that it looks red, what color of light is reflected by the paint? a) blue b) indigo c) red d) violet

The red light waves are reflected. If any colors of light are reflected by an object then that object will look the same color as the reflected light.

law of conservation of matter

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
