The answers are A. Pseudoscience is often based only on opinions; D. Pseudoscience often involves explanations of beliefs; E. Pseudoscience includes subjective ideas.
Explanation:
Pseudosciences comprises disciplines or theories that do not follow scientific standards but claim to be factual. This includes areas such as clairvoyance or astrology because this is not based on evidence but subjectivity. Indeed, the base of most pseudosciences are personal beliefs, opinions, or subjective ideas. Moreover, complex theories or methods are created to try to explain these beliefs, but because they do not follow scientific standards they are not considered as valid. In this context, options A, D, and E are correct.
Conversion factors are useful in solving problems in which a given measurement must be expressed in some other units of measure.
Conversion factors are helpful in solving issues where one unit of measurement needs to be expressed in another. In general, a measurement's numerical value changes when it is multiplied by a conversion factor, while the quantity being measured's real size stays the same.
A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value. For instance, 12 inches equals one foot when converting between inches and feet.

Answer:
It would look bigger and brighter
Answer:
The concentration of the solution is 1.068×10⁻⁴M
Explanation:
Hello,
To find the concentration of the solution, we'll have to use Beer-Lambert law which states absorption is directly proportional to the concentration of the solution.
Beer-Lambert law = A = εCL
A = absorption = 2 - log₁₀%T = 2 - log₁₀(34)
A = 2 - 1.5314 = 0.47
A = 0.47
ε = molar absorption coefficient = 4400
C = concentration of the solution
L = path length = 1cm
A = εcl
C = A / εl
C = 0.47 / 4400 × 1
C = 1.068×10⁻⁴M
The concentration of the solution is 1.068×10⁻⁴M
