Copper atoms and zinc atoms get melted together to form brass. Both atoms have similar atomic radius (135 pm). Based on that information, which of the following diagrams best represents the structure of this alloy and why?

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).

What is the mass of 8 moles of sodium atoms

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
