Write a balanced equation and draw an enthalpy diagram for (select if exothermic or endothermic):

So I'm reading my textbook and got very confused after learning about Anabolic/Catabolic reactions So bond breaking requires energy (energy needed to break the bonds), and is therefore endothermic. Therefore, bond making would release energy, therefore being exothermic. So here's where Im confused.. If Anabolism is BUILDING (aka MAKING bonds...),why does my textbook say that it's an endothermic process ? (because endothermic means energy IN when I was previously told bond making puts energy... Quoting this sentence from EK 10th Bio 2 (Systems) book. The topic is about how the respiratory system serves as a thermoregulator. "**Evaporation** is an exothermic process, so it has a cooling effect on the body." This sounded absolutely false. When I'm confused, I usually think about ice. You need heat to melt ice, so melting of ice is endothermic which is an expansive phase change (solid to liquid). And with that logic so too is evaporation. Can someone please confirm? This also explains ... Enthalpy diagrams for exothermic and endothermic processes.

B. Draw an enthalpy diagram for the reaction, showing the activation energy, Ea A thermochemical equation is a balanced chemical equation in which enthalpy change is variable. ∆H is negative for an exothermic reaction (a reaction where heat is given out), while it is positive for an endothermic... Write down the enthalpy change you want to find as a simple horizontal equation, and write ΔH over the top of the arrow. Working out an enthalpy change of reaction from enthalpy changes of formation. This is the commonest use of simple Hess's Law cycles that you are likely to come across. Enthalpies of formation are set ∆H values that represent the enthalpy changes from reactions used to create given chemicals. In other words, if you have to turn one or more of your formation reaction equations backwards in order to get all of your products and reactants to cancel properly, reverse the...

So if the sum of the enthalpies of the reactants is greater than the An enthalpy diagram plots information about a chemical reaction such as the starting energy level, how much energy needs to be added to activate... Obviously it would be some sort of estimate since the number of possible reactions is prodigious. But from what we know, are chemical reactions split roughly evenly between exothermic and endothermic?

Write and balance thermochemical equations. Calculate enthalpy changes for various chemical reactions. Define standard enthalpy of formation and write balanced equations for enthalpy of formation reactions. Explain Hess's law and use it to compute reaction enthalpies. Since enthalpy is a state function, the heat of reaction depends only on the final and initial states, not on the path that the reaction takes. A positive ΔHº value represents an addition of energy from the reaction (and from the surroundings), resulting in an endothermic reaction. Horizontal lines are drawn across the refrigerant's pressure enthalpy diagram for the suction and discharge pressures. This equation multiples the refrigeration flow rate by the change in enthalpy between the entrance and exit of the condenser. The x-y axes of the P-H diagram are the pressure... When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy The categorization of a reaction as endo- or exothermic depends on the net heat transfer.

like the title says, a thought experiment. it seems if the above is true then they would be contradicting each other if so. To the extent that either the Theory of Gravity is wrong or that light has mass which would lead to another problem being that when an object or mass reaches luminous speed it gains infinite mass, which then ends at singularities popping up all over the place. Unless i’m missing something here this would explain why a unified theory of gravity is necessary as this paradox ...

I was given this problem: * Consider two solutes that are equally solvated by water, but solute A has a much greater lattice energy in kJ/mol than solute B. Which of the two dissolution processes is more exothermic on a kJ/mol basis? This is the answer: * The greater the lattice energy of a solute, the more energy it takes to break it apart. Thus, since both solutes are equally solvated by water, the solute with the smaller lattice energy (B) will have an overall more exothermic dissolution p...

If that chemical equation comes with a ∆H, then you can easily determine the nature of reaction. Negative ∆H means the reaction is exothermic, while positive ∆H means the reaction is Having delta G will tell you right away if a reaction is exothermic or endothermic (negative means endothermic).

Greetings. I'd like to know how I can use EES to calculate enthalpy of steam, but in Excel. Enthalpy calculations require temperature and pressure.

I was reading about azeotropes when I read this part of the text which mentioned that: the mixing of ethanol and benzene is endothermic because the attractions between ethanol and benzene molecules are "less favorable" than between each type of molecule separately. Then vice versa for chloroform and acetone, where it stated the mixing was exothermic because the interactions between the acetone and chloroform molecules are "stronger" than those between molecules of chloroform or acetate separat...
