Which of the following equilibrium reactions
is NOT affected by a change in pressure
caused by a volume change to the vessel?
1. 2 H2O2(ℓ) → 2 H2O(ℓ) + O2(g)
2. 2 CO2(g) → 2 CO(g) + O2(g)
3. 2 BrCl(g) → Br2(g) + Cl2(g)
4. H2(g) + Br2(ℓ) → 2 HBr(g)
5. H2(g) + I2(s) → 2 HI(g)

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

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.
