Asolution was prepared by dissolving 140.0 g of kcl in 215 g of water.
calculate the mole fraction of kcl. (the formula weight of kcl is 74.6 g/mol. the formula weight of water is 18.0 g/mol.)
express the mole fraction of kcl to two decimal places

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.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
