Answer:
D. second order, 1/[A]t versus t
Explanation:
Since the power of the concentration is 2 in the rate law, it is a second order reaction. Also, for a second order reaction, the variables that would yield a straight line when graphed are 1/[A]t versus t
Light penetration plays a crucial role in the oxygen concentration in the ocean. Light can penetrate up to 50 to 100 meters of the ocean water, leaving high concentration of oxygen at ocean's depth.
The deep oceans are high in the concentration of oxygen. The rates of consumption of oxygen at such depth are low. The phytoplanktons are found in the photic zones of oceans, where these organisms perform photosynthesis. Phytoplanktons are not observed in the deep layers of ocean, therefore, the oxygen consumption will be low. The photosynthetic organisms yield oxygen as a by product, and use up carbon dioxide.
Therefore, the oxygen concentration at deep ocean levels will be higher.

B. Elements produce continuous spectra.
C. Elements produce spectra with only a few distinct lines.
Atomic emission spectra are unique to each element and consist of distinct lines representing different energy levels.
The correct statement regarding atomic emission spectra is option C: Elements produce spectra with only a few distinct lines.

d. radioactive dating.
D is the correct process to convert 36 yds to centimetres 2.54 cm = 1 in.
A metric unit of length, equal to one-hundredth of a metre.
To convert a yard measurement to a centimetre measurement, multiply the length by the conversion ratio. The length in centimeters is equal to the yards multiplied by 91.44.
