saw5 [17]3 years ago
6 0

Answer:

The direct channels by which extraction can affect the economy are of particular interest. The development of mines or oil and gas fields can result in significant shocks to a regional economy, generating jobs and drawing in capital from other regions and countries.

Answer: The final pressure is 0.81 kPa

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.58 kPa

P_2 = final pressure of gas = ?

V_1 = initial volume of gas = v

V_2 = final volume of gas = v-\frac{40}{100}\times v=0.6v

T_1 = initial temperature of gas = 25^0C=(25+273)K=298K

T_2 = final temperature of gas = -22^0C=(-22+273)K=251K

Now put all the given values in the above equation, we get:

\frac{0.58\times v}{298}=\frac{P_2\times 0.6v}{251}

P_2=0.81kPa

The final pressure is 0.81 kPa

   I                                 +1                                                           1

   II                                 +2                                                         2

   III                                +3                                                          3

   IV                           +4 or -4                                                     4

   V                                  -3                                                         5

   VI                                 -2                                                         6

  VII                                 -1                                                          7

  VIII                                 0                                                          8

For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)
