Equation 1
weight of 2 bolt = 6.75 weight of washer
Equation 2
mass = W/g
Where
g = 9.8m/s^2
mass of box of 2 bolt = weight of 2 bolt x 2 bolt pcs/box/9.8 m/s^2
mass of box of 2 bolt = 6.75 weightwasher x 2 bolt pcs/box
if there are 144 pcs of bolts/box
mass of box of 2 bolt= 6.75 weight of washer x 144/9.8m/s^2
mass of box of 2 bolt = 972 weight of washer /9.8m/s^2
=99.18 weight of washer s^2/m
Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
