How does Hess's law help us determine the enthalpy change of a reaction? How do you find the equivalence point on a titration curve? What is a neutralization titration? Explain the energy change calculations in chemical reaction. How to determine the process if it is endothermic ...
In this example you have the equation in the form of a line already. y=mx + b where y is lnP, m is -deltaHvap/R, x is 1/T and b is C. You are asked to determine the value of -deltaHvap given that the slope (m) is -8000 K. Can you find a way ...
Explain the energy change calculations in chemical reaction. How to determine the process if it is endothermic Describe briefly the term "exothermic reaction". Is energy created during an exothermic reaction? What is an example of an exothermic reaction?
Q. How do we determine the calorific value of food? Ans.To determine the number of kcals in a given food we directly measure the energy that it produces. Place the food in a sealed container i.e. a bomb calorimeter and surround it by water. Also, burn the food was complete. Then i...
SiO_2 2. Which has the greatest heat of vaporization? What happens when the vapor pressure of a liquid is equal to atmospheric pressure?Explain how intermolecular forces and kinetic energy determine the state of matter of a material.Which liquid, methanol or...
Determine ho If the heat of vaporization of water is 539.5 calories per gram, how many calories of heat are needed to vaporize 2.46 kilograms of water? How many joules does it take to raise the temperature of 2.00 L of water fro...
that their surface finish will gradually lose effectiveness over time. For ENIG boards, the industry usually sets a shelf life of 12 months. After this time, the thickness of the gold layer and the quality of the storage conditions will determine whether the board can still be used. If the...
In engineering and HVAC design, it's used to determine the best conditions for human comfort. I'll mention a couple more charts in a minute, but first a bit about Psychrometry which is the study of the physical and thermodynamic properties of air and water vapor mixtures. Air and water ...
Every substance can change its physical state according to the temperature. The rise and fall of temperature can convert a substance can change a solid into liquid and gas and vice versa. Answer and Explanation: Melting Point: The melting point ...
