Plzzz I need help ASAP! Question: Now build a model of liquid water. Place your materials on a sheet of paper. The regular-size marshmallows can represent the larger oxygen atoms, and the mini marshmallows can represent the smaller hydrogen atoms. Connect the marshmallows with toothpicks using the picture as a guide. Create a total of four molecules. What was difficult about building the model?

How does a hydroelectric power plant converts energy into energy.

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
