Condensation and rarefaction in a longitudinal wave correspond, respectively, to what parts of a transverse wave? group of answer choices :
wavelength and amplitude
period and frequency

Wavelength

Explanation:

Compression and rarefaction in a longitudinal wave correspond respectively, to the wavelength of a transverse wave.

Compression is the part of a wave where the density of particles are very close to each other while the rarefaction is the part of a wave where the particles are far apart from each other.These are the parts of longitudinal waves.

So, the correct option is (a) "wavelength".

  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
