If wet silver carbonate is dried in a stream of hot air, the air must have a certain concentration level of carbon dioxide to prevent silver carbonate from decomposing by the reaction:
ag₂co₃(s) ag₂o (s) + co₂(g)
∆h° is 79.14 kj/rxn for this reaction in the temperature range 25 to 125°c. given that the partial pressure of carbon dioxide in equilibrium with pure solid silver carbonate is 6.23 x 10-3 torr at 25°c, calculate the partial pressure in torr of co₂ necessary to prevent decomposition of ag₂co₃ at 99°c.

Calcium hydride (cah2) reacts with water to form hydrogen gas: cah2(s) + 2h2o(l) → ca(oh)2(aq) + 2h2(g) how many grams of cah2 are needed to generate 45.0 l of h2 gas at a pressure of 0.995 atm and a temperature of 32 °c?

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
