aqueous hydrochloric acid and aqueous magnesium hydroxide combine to produce magnesium chloride and water. suppose 18.0 g of magnesium hydroxide was combined with 18.0g of hydroxide acid. how many grams of water should be made?

What will most likely happen when two bromine atoms bond together?

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.)
