What advantage does a modern camera offer a pinhole camera

Done

Explanation:

The differences are significant. The main disadvantages of a pinhole camera compared to a modern camera are:

Proper exposure requires a trial and error approach.

Requires manual control of shutter speed (difficult to control)

Poor image quality (due to diffraction effects).

Long exposures (lead to blurry images if the subject moves).

Fixed aperture or f-stop.

Advantages include:

Large depth of field.

Inexpensive

Robust and nearly 100% reliable.

If used properly can create artistic effects.

  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

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
