How many moles of each molecule are represented in the equation, 2H2 + O2 + 2H20? A
2, 1, 1
B
2, 2, 2
C 2, 1, 2
D 1, 1, 1

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
