If you react 20, and 4H , how many atoms of hydrogen and how many atoms of oxygen will there be in the product?​

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

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.
