For all simple substances, their standard enthalpies of formation are 0 kJ·mol-1 at room temperature C. If ∆rSmӨ< 0, the reaction is spontaneous D. Because the decomposition of CaCO3(s) is endothermic, the standard molar enthalpy of CaCO3(s) formation is negative ...
Is oxidation endothermic or exothermic? If ClO_{3}^{-} is a reactant in a redox reaction and Cl_{2} is a product of the same reaction, the number of electrons involved in the reduction half reaction is ___. When iron rusts the iron metal reacts spontaneously with oxygen to form ir...
For each reaction, determine how the oxidation state of the carbon atom changes. a. C3H8(g) + 5O2(g) rightarrow 3CO2(g) + 4H2O(l) (combust What's the balanced chemical equation for the combustion of carbon? What type of chemical reaction is combustion? Is decomposition a chemical reac...
What is a decomposition chemical reaction? What is the product formed from the reaction of formic acid and sodium hydroxide? What type of reaction occurs during an acid-base titration? How can you make a chemical reaction? What is released or absorbed during a chemical reaction?
