Thanks+ BRAINLIST only for correct answers AM radio waves have a
a. Shorter broadcast range than FM waves
b. Longer broadcast range than FM waves
C. Better quality sound than FM waves
d. More music options

FM radio travel a shorter distance than AM radio waves.
a. true
b. false

Radio stations, police radios, and amateur radios don't interfere because they
have different
a. volumes
b. music options
C. frequencies

First) is b

Second) is true

Third) is C (not sure tho)

Explanation:

Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere.

  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

answer: b.
