How much heat is absorbed by the calorimeter (qcal) if the temperature is increased 12.4 C and the calorimeter constant (Ccal) is 3.30 J/C? A 65.45g piece of zinc metal at 75^\circ C was dropped into a calorimeter containing 125mL water at 19.9^\circ C. IF the apparatus comes to ...
What type of reaction is used in calorimetry? The water in a bomb calorimeter was replaced with the organic compound methylene chloride (CH_2Cl_2). Burning 2.23 \ g of glucose (C_6H_{12}O_6; DH_{comb} = 22801 \ kJ/mol) in the calorimeter causes its temperature to rise 9.64^oC....
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
No calorimeter is perfect because it can lose heat to its surroundings. Although bomb calorimeters in laboratories have insulation to minimize these loses, it's impossible to stop all heat loss. Moreover, the reactants in the calorimeter may not be well-mixed, which leads to uneven heating a...
What does a calorimeter directly measure?Counting CaloriesA calorimeter is a scientific instrument used by biologists, chemists, and physicists that is capable of making very fine measurements of particular quantities down to a finite amount.Answer and Explanation: ...
In the lab, you can put nutrients or foods in what is called a bomb calorimeter (which would be a great band name: let’s welcome to the stage Bomb Calorimeter, followed by The Thermic Effect of Food!!!) and burn them. And then you measure the amount of heat given off. And...
If 0.5calg−1C−1 is the specific heat capacity of a substance of mass 50 g, calculate the amount of heat energy required to change the temperature of a substance from −5∘C to 10∘C A250 cal B125 cal C375 cal D500 calSubmit A bomb calorimeter has a heat capacity of 783...

A device known as a bomb calorimeter is a very common example. This piece of equipment is typically made out of a steel casing — a "bomb" — that will not change in volume. The reactants are placed inside of the bomb and the bomb placed inside of another container filled with water...
athe process which takes place in the bomb calorimeter is an adiabatic combustion at constant volume with a change in internal energy . 在原子弹热量计发生的过程是绝热燃烧在恒定的容量与在内能上的一个变化。[translate] aBitch is cheap 母狗是便宜的[translate] ...
