Consider the rate law below. r=k[a]^2 . what effect does doubling the concentration have on the rate ? a - doubles the rate b - triples the rate c - quadruples the rate d - no effect on the rate

Explain what happens at the saturation point when adding salt to water at room temperature.

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.)

Which of the following is most likely true about water in chemical solutions?
