Arnold makes a chart to summarize what happens when light interacts with matter and is reflected. a 2 column by 4 row table. column 1 is titled type of interaction and contains the following entries: specular reflection, diffuse reflection, scattering. column 2 is titled description and contains the following entries: occurs when light strikes smooth surface, follows the law of reflection, reflected rains move in the same direction, occurs when light strikes rough surface, follows the law of reflection, reflected rays move in different directions, occurs when light strikes particles in atmosphere, follows the law of reflection, short wavelengths are scattered the most which best describes arnold’s error? in specular reflection, reflected rays move in the same direction. in scattering, short wavelengths are scattered the least. in diffuse reflection, reflected rays move in the same direction. the law of reflection is not followed in scattering.
the law of reflection is not followed in scattering.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

double the distance = divide strength by 4

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
