Opinions are bent, linear, Tetrahedral, trigonal pyramidal, and trigonal planar Match the following descriptions with their correct electron group
geometry.
A molecule has a central atom
with two single bonds and a
double bond. Example carbonate ion
A molecule has a central atom
with only two electron groups.
Example HCN
A molecule has a central atom
with three single bonds, and a
lone pair. Example ammonia
A molecule has a central atom
attached to only two double
bonds. Example CO2

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

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

answer: they produce more slow than unicellular organisms.
