Gabriel is studying a newly discovered element. Through his work, he has proven that this element can exist in the form of 3 different stable isotopes: X - 413, X - 415, and X - 416. He has determined that the natural abundance for each isotope is 62%, 24%, and 14%, respectively. Which of the following would most likely be the average atomic mass for this element?

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.
