Gas at 25ºc, 1 atm enters an insulated reactor operation at steady state, where it burns with 200% excess air entering at 25ºc,1 atm. an equilibrium mixture of co2, co, o2, h2o and n2 exits at 1 atm. determine the temperature of exiting equilibrium mixture in k.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

What is the primary force that suspension bridges use cables to hold their spans up? a. tension force b. resistance force c. normal force d. elastic force e. applied force

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
