Energetics Definition and 12 Threads

HI EVERYONE. I'm a beginner in system codes for nuclear thermal-hydraulics simulation and i hope to exchange informations about simulations with system codes , like RELAP/SCADAP I thank the creators of this forum, as well as the members who are there for the scientific exchange and the help of...

I am sure this question will have been asked elsewhere, so please forgive me if it has. My question involves the transfer of electrons in ionic bonding. We are told that a metal will give up its outer most electron because by doing so it will gain the electron configuration of a noble gas...

I am curious as to what is the Standard Enthalpy Of Formation is of Tetraoxygen in kJ/mol. I am assuming reference to the molar weight of the Tetraoxygen molecule. I seem to only find papers on the subject which are abstruse with detail but no clear answer to my inquiry. I have little formal...

If so, why do people use the word "energetics"?

My understanding and application: Flowing blood with mass m, and velocity v has KE proportional to mean velocity squared as blood flows inside the vasculature, pressure is also exerted laterally against the walls of the vessels So, it is then reasonable to use Bernoulli's for the blood and...

Hello, I have never been able to keep straight in my head if making bonds and breaking bonds are exothermic or endothermic. Is there any way that someone can explain why which is which in a way that is understandable because I'm tired of constantly having to re memorize it.

please can anyone explain me in simple words why energy is released when bonds are formed?

I am a 1st year physics student at the University of Edinburgh, who's also taking chemical engineering as an outside course. I am intersted in being involved in the energetics industry after gradutation. Could someone provide insight as to (1) what type of courses should I choose in physics and...

Given: Planet is orbiting a star G = 6.67259 x 10^-11 Nm^2/kg^2 Mstar = 1.99 x 10^30 kg mplanet = 5.98 x 10^24 kg distance from perihelion to star = 1.69 x 10^11 m distance from aphelion to star = 1.745 x 10^11 m potential energy at perihelion = -4.698 x 10^33 J Need: Kinetic...

1. Homework Statement The standard enthalpy change of combustion of propane (C3H8) is -2220kJ/mol. It requires 1.0J of energy to raise the temperature of 1.0g of air by 1.0K. Calculate what mass of propane needs to be burned to raise the temperature of the air in the balloon by 50K. 2...

last question Calculate the energy change for the formation in kJ of 0.39 mol of KI(s) given the following information: I2(s) --> I2(g) : 62.44 KJ/mol K(s) --> K(g) : 180.4 KJ/mol 1/2 I2(g) -->I(g) : 138.05 KJ/mol K+(g) + e- --> K(g) ...

Energetics of Organic Compunds!help The energy of interaction between a Mg cation and a Cl anion is -4.000 x 10 -19 J What is the distance in Angstroms between these two ions? Enter a numerical answer only, do not enter units. i tried and tried and can't get this...
