Consider the reaction. A(aq) = 3 B(aq) K. = 1.18 x 10^-6 at 500K If a 2.00 M sample of A is heated to 500 K, what is the concentration of B at equilibrium?​

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.)

Find the mass, in grams, of 5.00*10^23 molecules of f2
