Calculate the molarity of a solution prepared using 128 grams of KCL with a volume of 552 mL

The number to the right of an element's symbol (ex. c-12) identifies the of an isotope.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
