What is the specific heat capacity of a substance that has a mass of 25.0 g and requires 52.0 calories to raise its temperature by 18.0°C? *

What neutral atom is isoelectronic to mn+4

In an oxidation-reduction reaction, oxidation is what happens when a reactant

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.)
