Chemistry definition correct answers Study of structure, properties, transformations of matter Matter correct answers Anything that has mass + takes up space Phases: solid, liquid, gas Condensed phases = solids + liquids Intermolecular Forces (IMF) correct answers = Interactions between molecules/atoms/ions Solution correct answers = Homogenous mixtures of 2+ pure substances In a solution, the solute is dispersed uniformly throughout the solvent - Solute = compound(s) in lesser amount - ...

What is work? correct answers the product of force and distance W = F⋅ d *where W is the work done, F is the magnitude of the force, d is the magnitude of the displacement What is energy? correct answers *Defined as the exertion of force (kinetic) or the capacity (potential) to do work. *Energy can be expressed as mechanical work, chemical reactions, or heat. *The unit of measurement for energy is the joule. *A joule is the force of 1 N that moves its point of application 1 m in the...

MCB 3020 Exam TWO Study guide List the laws of thermodynamic and describe their relevance in the chemical reactions - Answer- Energy can not be created/destroyed. Total universal energy is constant. Energy may be redistributed. Entropy - requires energy to put molecules together. Define the standard reduction potential. - Answer- Equilibrium constant for an oxidation-reduction reaction. Measures the tendency of the reducing agent to lose electrons. Why does aerobic growth generate the...
