Brady notices that when he places a straw in a glass of water, the image of the straw in water and the image of the straw outside of the water do not match up. What is the reason for the difference in how the straw looks above and below the water? A:Light travels faster through water, refracting the image
B:The surface of the water reflects the image of the straw
C:Light travels faster through air, refracting the image of the straw
D:The light is reflected several times in the glass, creating a false image

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

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

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants
