Questions and Videos on Thermochemistry with Equation Stoichiometry, within Chemistry

Jan 17, 2018 · The material is heated; thus, it is expected that the temperature of the material will also increase. This problem can be solved using the standard formula: Q = mCpΔT where: Q = …

You use the standard enthalpies of formation. To calculate the enthalpy change for a reaction, in your case for the combustion of ethane, you can use the standard enthalpies of formation of …

Using the data given, the heat of combustion would be 308 kJ/mol. To calculate the heat of combustion, you must determine the amount of heat energy released and divide by the …

What is the definition of human anatomy and physiology? What is an example of each? Does anyone have any tips for how to study the names of bones, and the different parts of bones for …

Dec 19, 2017 · Here's how you can do that. For starters, you know that in order to melt "100 g" of ice at its normal melting point, i.e. to go from ice at 0^@"C" to liquid water at 0^@"C", you …

It is matter. The definition for matter is anything that has mass and takes up space (has volume). It is the "stuff" of which things are made. The basic building blocks of matter are atoms. The …

Can you please explain how to use bond energies to determine the change in heat for reactions, or maybe post a link to a video on thermodynamics/ thermochemistry? How to estimate (Delta …

By definition, the relative humidity will be 100% when the temperature reaches the dew point. The dew point is the temperature at which the relative humidity is 100% (which is another way of …

Aug 3, 2016 · Here's what I got. The idea here is that the heat given off by your reaction will be absorbed by the calorimeter. -q_"given off" = q_"absorbed" The minus sign is used here …
