Answer:

The main basis for the classification system is the way rocks were formed. With these criteria there are three different types of rocks:

  • Igneous rocks :  formed through the cooling and solidification of magma or lava
  • Sedimentary rocks : formed by the accumulation or deposition of small particles
  • Metamorphic rocks: formed by the transformation of existing rock types by heating and pressure

In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

An aqueous solution 10 g of an optically pure substance diluted to 500ml with water and placed in a polarimeter tube 20 cm long.
Gennadij [26K]

Explanation:

Formula to calculate specific rotation is as follows.

        Specific rotation ([\alpha]) = \frac{\alpha}{c} \times l

where,    \alpha = observed rotation

                   c = concentration in g/ml

                   l = path length in dm

It is given that,

             \alpha = -6.16^{o}    

               c = \frac{10 g}{500 ml} = 0.02 g/ml

              l = 20 cm = 2 dm   (as 1 dm = 10 cm)

Therefore, calculate the specific rotation as follows.

      Specific rotation ([\alpha]) = \frac{\alpha}{c} \times l

                        = \frac{-6.16^{o}}{0.02 g/ml} \times 2 dm

                        = -616^{o}

Thus, we can conclude that the specific rotation of this compound is -616^{o}.
