The four rows of data below show the boiling points for a solution w/ no solute, sucrose (C6H22O11), sodium chloride (NaCl), and calcium chloride (CaCl2) (not in that order). Which boiling point corresponds to calcium chloride? A. 101.53 C Which of the following solutions will have the lowest freezing point? C. 1.0 mol/kg sodium phosphate (Na3P) Which of the following compounds will be most effective in melting the ice on the roads when the air temperature is below zero? D. All ...

Elastic Objects interact with each other without producing sound, heat, or light *Both momentum and kinetic energy are conserved, total momentum and kinetic energy before and after are the same Ex: the two magnets facing each other Inelastic Sound, heat, or light are produced, so kinetic energy is NOT conserved *Kinetic Energy is different before and after the collision, BUT momentum is conserved Completely Inelastic Two objects strike each other and stick together *Kinetic ...

In order for a chemical reaction to take place, what must occur? All answers are correct When two or more reactants combine to form one or more products, what has occurred? chemical reaction Which of the following can impact the reaction rate? All answers are correct Choose the BEST answer that finishes this statement about the collision theory: the speed of chemical reactions is related to: the number of successful collisions Which of the following is true about ...

Protecting passengers in a collision In a collision (e.g. car crash): there's a sudden change in momentum. A large force can be exerted on passengers by rapid deceleration, causing injuries. Seatbelts, crumple zones, and airbags in cars help reduce injuries in a crash by reducing momentum more gradually. Each of these features also absorbs some of the energy of the collision and transfers it into a less dangerous form. Seatbelt How it works in a crash: Stretches, rather than holdin...

Absolute brightness the intrinsic brightness of a star that depends only on its luminosity. Apparent brightness how bright a star appears to an observer on Earth. Mpc Astronomers describe the apparent brightness of a star as the ratio between the brightness of the star to the brightness of the Sun when viewed from a distance of 1 _____________ . For example, a star with an apparent brightness of 10 is 10 times brighter than the sun would be if viewed from a distance of 1 _______...

Which of the following statements correctly expresses collision theory? Reactants collide with reactants to form activated complex that separates into products. For the chemical reaction CH3Br + OH- ----> CH3OH + Br -, which of the following would speed up the reaction? Increasing the CH3Br concentration Both beakers contain a liquid substance that will react with the substance represented by the gray dots. Which statement is true about this chemical reaction system? Containe...
