A0.50 molar aqueous solution of hydrochloric acid (hcl) flows into a process unit at 25°c and a rate of 1.25 m3/min. if the specific gravity of the hcl solution is 1.03 at 25°c determine: a) hcl concentration in kg/m3 b) mass flow rate in kg hcl/s c) massfractioninkghcl/kgsolution d) mole ratio in mol hcl/mol water e) molar flow rate in kmol hcl/s

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
