How are human population growth and fracking related?

Chemistry
1 answer:
PilotLPTM [1.2K]4 years ago
4 0

Answer:

The answer is B. The population has increased and so has demand for energy resources.

Explanation:

Fracking is a technique used to increase the extraction of gas and oil from the subsoil. It consists of extracting small dispersed concentrations of hydrocarbons (it can also be done with oil). To do this, a vertical drilling of four or five kilometers is carried out and then water mixed with chemicals is introduced to fracture the rocky substrate, filtering the fuel into the conduit. Fracking is used due to the scarcity of resources and the reduction of reserves. So, while the population continues to increase, the demand for energy also increases. This leads to fracking being used to meet the high demand.

Calculate the mass of 120cc of nitrogen at stp .how many numbers of molecules are prrsent
Ratling [72]

Answer:

3.2 x 10²¹molecules

Explanation:

Given parameters:

Volume of nitrogen gas = 120cm³

Unknown:

Mass of nitrogen gas = ?

Number of molecules  = ?

Solution:

To solve this problem, note that;

   1 mole of gas occupies a volume of 22.4L at STP

  Now;

   convert 120cm³ to L ;

           1000cm³  = 1L

           120cm³ gives 0.12L

    Since;

            22.4L of gas has 1 mole at STP

            0.12L of gas will have \frac{0.12}{22.4}   = 0.0054mole at STP

So;

    Mass of N₂  = number of moles x molar mass

 Molar mass of N₂  = 2(14) = 28g/mol

    Mass of N₂  = 0.0054 x 28  = 0.15g

Now;

        1 mole of a gas will have 6.02  x  10²³ molecules

      0.0054 mole of N₂ will contain   0.0054 x  6.02  x  10²³ =

                          3.2 x 10²¹molecules

What process uses analysis of the decay of atomic particles to determine exact age?
padilas [110]

Answer:

Radioactive dating

Explanation:

Radioactive dating measures the ratio of C¹²(normal) and C¹⁴ (radioactive) in fossils to determine the exact age of the specimen. C¹⁴ is unstable and has a half life of 5730 years, so as the organism ages the amount of C¹⁴ diminishes but the amount of C¹² remains constant. The ratio of C¹⁴ to C¹² is used to analyze the decay of atomic particles to determine exact age.
