Aheat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 450°c enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. chlorine gas enters the exchanger at 1 bar and 27.0°c and leaves the exchanger at 132.0℃ assume the heat exchanger is adiabatic. th ecanat r dlaseum dsd what is the specific enthalpy of the inlet steam stream? (use liquid water at 0.01℃ as a reference state.) number what is the specific enthalpy of the outlet steam stream? (use the same reference state.) number kj/ kg se what is the specific enthalpy of the inlet chlorine gas stream? (use chlorine gas at 1 bar and 27.0°c as a reference state.) number kj/mol

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?
