decomposition reaction.

molar mass of HgO is 200.6 +16 =216.6

2HgO2Hg + O2(g)

1.65 kg HgO = 1650gm/216.6=

7.62 moles )

2 moles of HgO gives 1 mole of O2

7.62 moles gives 3.81 moles O2

molar mass O2=32

3.81 moles of O2=3.81 X 32 =121.92 gm O2 released

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
