How many grams of water are needed to react with 37.2 g of Li2O? Given: Li2O + H2O → 2LiOH

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

Identify arrows pointing to bonding electrons. done h-0-0-h ) intro

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
