suppose you have two cans, one with milk, and the other with refried beans. Both cans have the same size, shape, and mass. If you release both cans at the same time, on a downhill ramp, which would have the most energy at the bottom of the ramp? ignore friction and air resistance.. a.can with beans b. can with milk c. both have same energy please explain your answer
TILCIUILL Formaldehyde (CH2O) appeared in your exam. (a) Use Lewis structures to show a molecule of formaldehyde forming hydrogen bonding attractions with a molecule of water. CLEARLY identify the donor and acceptor in this drawing. (b) Referring to your drawing above, briefly explain why two formaldehyde molecules can't form hydrogen bonding attractions between each other. (©) Formaldehyde molecules are twice as massive than both ammonia (NH3) and water (H2O). And yet, formaldehyde has nearly the same boiling point as ammonia,...
Square soda bottle is proposed to replace the traditional cylindrical shape. Both have the same height for packaging and storing purpose. *Use HDPE plastics for both shapes *Bottle cross section: 4 inch square or 4 inch diameter, 0.050 inch thick *Blowing pressure: varies *Assume tensile strength of HDPE is 20% lower than that at room temperature a) Find the blowing pressure that bursts each container at molding temperature of 170 F b)Which is cheaper to produce? Why?
Polar molecules tend to have high boiling points. Explain why polar molecules require a high energy to phase change.
While monosaccharides typically all have a molecular formula that is a multiple of CH2O, they differ in factors such as the length of the carbon skeleton or the orientation of their atoms around asymmetric carbon atoms. What is the impact of this variation in molecular structure? A. Different monosaccharides will form disaccharides with the same properties. B. Cells will use more energy to metabolize a wider variety of polysaccharides. C. Molecules that all share the same bonding pattern but have...
10 Both of the molecules shown below have the same molecular formula. C2HO One of these molecules boils at-24°C and the other molecule boils at 78.37°C. НН НН (i) which molecule boils at the higher temperature - molecule (I) or molecule (l) (% point) (ii) what kind of bonding exists between molecules of molecule (0)? 1% point) (ii) what kind of bonding exists between molecules of molecule (I)? 1% point)
9.1 Explain the concepts of the VSEPR model. Explain why molecules take the shapes they have Define an electron domain Draw dot diagrams and determine appropriate domain geometry based on the diagram From the dot diagram and the domain geometry, determine approximate bond angles is a substance. 9.2 Determine the molecular geometries of molecules. Draw a dot diagram or when given a dot diagram determine the appropriate molecular geometry Explain why non-bonding pairs and double and triple bonds cause the...
NH3, has the same molecular shape as PCl3. Which intermolecular forces are present between NH3 molecules? How are they different than the forces between PCl3 molecules?
Explain why nonpolar molecules usually have much lower surface tension than polar ones.
