All forms of HF can cause severe burns to tissue, which makes its handling and use especially hazardous. HF easily dissolves glass and can attack enamels, pottery, concrete, rubber, leather, many metals and organic compounds. Upon reaction with certain metals, explosive hydrogen gas may be formed.
WebSome substances form more easily than others. For instance, it's not hard to form oxygen gas - gaseous O2 is in its natural state, so its heat of formation is zero. On the other hand, it takes a lot of energy to oxygen into a liquid, so … WebCalculate the enthalpy of formation of propane gas, given the following information.
