Drag each tile to the correct location. Classify the reactions as endothermic or exothermic.
Possible Choices:
1.) The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.
2.) Three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes beaker hotter.
3.) Ammonium chloride dissolved in a beaker of water makes the beaker cold.
4.) Uranium atoms are split to produce nuclear energy.
5.) Water separates into hydrogen and oxygen when an electric current runs through it.
6.) Methane and oxygen are combined to produce methanol and heat.

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.)
