С какими из веществ формулы которых H2S, Fe, S, CaCO3, Al, P, BaSO4, будет взаимодействовать концентрированная нитратная кислота? напишите уравнения возможных реакций и название веществ.

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.)

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?
