The synthesis of NH3 is represented by the equation above. Based on the equilibrium constant, K, and ΔH°rxn given above, which of the following can best be used to justify that...

AP Chemistry | Unit 3 Progress Check: MCQ: 2023. (two diagrams shown above) Which particle diagram shown above best represents the strongest intermolecular force between two ethanol, C2H6O, molecules? C) Diagram 2, because it shows the formation of a hydrogen bond between an H atom bonded to an O atom with an O atom from another molecule. (Li+, Mg2+, Na+, and Ca2+ cations shown above) The diagram above represents four cations, all shown to the same scale. Which cation would be predicted by ...

Why are alpha particles deflected by the nucleus? - Answer-Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." - Answer-False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic particles? - Answer-The nature of the electron is i...

Friction - The force that always opposes motion Coefficient of friction - Force of friction divided by normal force Net force - Resultant force, the sum of all forces acting on an object Free body diagrams - Physical model of a representation of forces acting on a system 2-dimensional motion - Any motion of an object is more than one line, a plane Vector independence - Changes in one vector do not cause changes in another Projectile - Any object launched into the air with no force other th...
