What is the definition of a lewis base? a substance that donates a proton a substance that donates electrons to form a covalent bond a substance that accepts electrons to form a covalent bond a substance that when dissolved in water increases hydrogen ion concentration

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

Ethyl alcohol, also known as ethanol, has a density of 0.79 g/ml. what is the volume, in quarts, of 1.95 kg of this alcohol?

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.
