How is the image that you see through the lens different from images that you see using your eye?

the image you see through a lense is different then you see with your eye because the lense is stained a certain way to prevent exposure to dangerous things because it filters it out, also its because the lense were made a special way with certain chemicals that also produce that effect, meaning that the color spectrum is different when you look at certain things with a lense.

Explanation:

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
