4nh3 + 6 no → 5 n2 + 6 h2o. how many moles of no are required to completely react with 2.45 mol nh3? show all of your work as well as the answer with the proper units.

What is the mass of 0.46 mil of mgcl2

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.)

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.
