If you add two or an ext thermochemical equations to provide a final equation, you can also include the heats the reaction to provide the final heat that reaction
What three determinants do you need to recognize in order to calculation the heat readjust of a chemical reaction in a calorimeter
When heavy steam is offered to journey a turbine, the kinetic energy of the moving turbine will certainly be much less than the power used at first to warmth the water come steam. Describe why this is no a violation that the law of preservation of energy.

You are watching: The amount of heat required to raise the temperature of 1 gram of a substance by 1°c is called

The power that is no converted come kinetic energy escapes together heat. Friction reasons the surroundings to come to be warm, therefore this thermal energy makes that so that the energy in out equates to the power output.
The value of deltaH for a chemical reaction is negative. What does this indicate around the chemical power of the commodities of the reaction contrasted to that of the reactants? Explain.
This method that the product is an exoteric reaction because it"s shedding heat, while the reactants are endothermic reactions.
Explain the distinction between warmth capacity and certain heat. Provide an example to highlight this distinction.
Heat capacity is the amount of warmth needed to change an object"s temp by 1 degree C. Certain heat is the heat forced to progressive the temp of ONE GRAM of problem by 1 degree C. For example, you"d require a larger heat capacity to warm a bigger amount the steel. However, two different quantities of steel have the same details heat.
What is the function of the water exterior the reaction room of a calorimeter? Why does the water bath in a calorimeter have to be insulated?
The water absorbs the warm from the sample, and also it needs to it is in insulated so the doesn"t shed its warmth to the surroundings.

Using what you know about physical changes, why does heavy steam at 100 levels C create a an ext harmful burn 보다 boiling water?
Steam contains much more energy 보다 boiling water in ~ 100 degrees C. Also, steam releases an ext heat as soon as it condenses to a fluid on contact with skin.
Change the kJ that the equation the doesn"t have actually the very same product together the initial product come a negative value, then include together
