Consider the following reaction (assume an ideal gas mixture). 2NOBr(g) -> 2NO(g) + Br2(g) A 3.0-L vessel was initially filled with pure NOBr, at a pressure of 3.7 atm, at 3290 K. After equilibrium was reached, the volume was increased to 2.0 L, while the temperature was kept at 300 K. This will result in:

A. an increase in Kp.
B. a decrease in Kp.
C. a shift in the equilibrium position to the right.
D. a shift in the equilibrium position to the left. E) none of these

a) the particles of the chair are strongly held together.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

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.
