The heat change that accompanies the formation of 1.00 mol of carbon dioxide from its elements is -393.7 kJ/mol. What heat change accompanies the formation of 0.650 mol CO₂? colom
When calculating enthalpy of reaction values, we use the "products minus reactants" mathematical model. Which explanation of this model is most correct? A) The products are coming into existence, thus we use their enthalpy of formation. The reactants are ceasing to exist, thus we use the opposite of their enthalpy of formation. B) "Products minus reactants" is an equation, not a model, and thus tells us nothing about the reaction. C) We model the chemical reaction as taking reactants and turning them into products. The exact steps don't matter as long as it comes to the product eventually. That is why we use "products minus reactants." D) We model the reaction as taking reactant molecules and dispersing them in to pieces (the opposite of the formation reaction of the reactants) and taking those pieces and condensing them down into products (the same as the formation reaction for those products.) Thus we take the negative of the enthalpy of formation for the reactants and…
A decomposition of hydrogen peroxide into water and oxygen gas is an exothermic reaction. If the temperature is initially 28˚ C, what would you expect to see happen to the final temperature? Explain what is happening in terms of energy of the system and the surroundings. endothermic or exothermic?
can you explain why energy must initially be consumed in an exothermic chemical reaction?
Your barbecue grill uses propane (C3Hg) to cook your food while butane (C4H10) is used in chemistry laboratories to perform experiments. Write an equation for hydrocarbon combustion for each of the gases and then balance. Are these reactions endothermic or exothermic? How do you know? Assume that the gases burn clean and completely, calculate the energy released by each in kJ/mole. Calculate the energy released in kJ/g. Which gas is more efficient? Be sure to show all of your work!
The Haber process is exothermic. (the formation of NH3 from its elements) a) Write out the balanced chemical equation (with subscripts) and include energy.
In an endothermic reaction the enthalpy of the reactants is greater than the enthalpy of the products. In an endothermic reaction, the energy required to break existing bonds is more than the energy released when new bonds form. In an exothermic reaction the energy required to break existing bonds is less than energy released when new bonds form. In an exothermic reaction the potential energy of the reactants is higher than the potential energy of the products and the energy term would be written on the product side of the equation.
From a molecular viewpoint, where does the energy absorbed in an endothermic chemical reaction go? Why does the reaction mixture undergo a decrease in temperature even though energy is absorbed?
For an exothermic reaction, how is the measured temperature change affected if some of the heat produced transfers to the calorimeter? How will the determination of the specific heat of the metal be affected if the thermometer used to record the temperature of the water bath reads too low?
