Refer to the image shown to answer the question. If a light ray is reflected off the shiny surface at 170 degrees, at what angle did the light ray first strike the surface?
Incident rays are shown at 10, 30, 50, and 70 degrees. The line at 90 degrees is labeled normal. Reflected rays are shown at 110, 130, 150 and 170 degrees.

70 degrees

170 degrees

10 degrees

110 degrees

Concerning the 10.0 ml of 0.50 m nacl to 100 ml of solution: when a solution is diluted, does it change the number of moles dissolved?

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
