Two identical vessels are filled, at the same temperature and pressure, with different gases. One is filled with hydrogen and the other with carbon dioxide. Which statement is correct?.

What effect does a decrease in temperature have on the overall rate of a chemical reaction? a decrease in temperature decreases . the reaction rate will

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.)

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
