cuál será la densidad de un material que tiene 450g de masa y un volumen de 50 ml? por favor esto lo tengo q entregar mañana ayudA Dx​

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

What statement goes against the kinetic theory of gases

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
