Mr. Britt is pouring a 36' x 58' concrete pad for a metal building. If concrete costs $123.00 per cubic yard, what will be the cost of the concrete to pour the pad 8 inches
thick? A cubic yard of concrete = 27 cubic feet and Cu. Ft. = T’xW'x L' (Round up
to the nearest cubic yard when calculating concrete needed.) Pls help me
a. $5,047.00
b. $6,396.00
C. $6,564.00
d. $7,329.00

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
