The image compares the arrangement of electrons in two different neutral atoms. Atom P
Atom Q
Which of the following best explains the position of the two atoms in the periodic table?
O Atom P has an estimated Zaft of 7 and is therefore to the left of Atom Q which has a Zet of 6.
Atom P has an estimated Zet of 7 and is therefore to the right of Atom Q. which has a Ze of 6.
O Atom P has an estimated Zam of 5 and is therefore below Atom Q. which has a Zef of 4
Atom Phas an estimated Zer of 5 and is therefore above Atom Q. which has a Zof 4

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

that tool would be a compass
