A narrow ray of yellow light from glowing sodium ( = 589 nm) traveling in air strikes a smooth surface of water at an angle of 35.0°. Determine the angle of refraction.

Low

When you're feeling low

And you just don't know where to run to

Broke

If your heart's been broke

And you feel like you're all alone

If you need something to believe in

If you're looking for a light to guide you home

Just look inside

You light a shining brighter than you know

And if nothing else, you can always count on that

When you need me I promise I will never let you down

Laugh

I will make you laugh

If you ever feel like crying

Close

I will hold you close

You won't be alone anymore

Explanation:

answer: strength i guess

explanation:

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
