To calculate the amount of heat released in a chemical reaction, use the equation **_Q = mc ΔT_**, where **_Q_** is the heat energy transferred (in joules), **_m_** is the mass of the liquid being heated (in kilograms), **_c_** is the specific heat capacity of the liqu...
How to calculate enthalpy change Enthalpy Change:Enthalpy change is a measure of the amount of energy released or absorbed during a chemical reaction. A negative enthalpy change indicates that heat was released (known as an exothermic reaction), while a positive enthalpy change indicates that heat ...

Multiply the specific heat of water by the mass of the water in grams and the change in temperature of the water in degrees Celsius to calculate the heat taken in by the water. The specific heat of water is 4.184 joules per gram 1 degree Celsius, so given 1,000 grams of water and a...
Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ Since you are asked for the change...
Procedure to Calculate Calorific Value It is the measurement of the heat value or amount ofenergyreleased and is either measured in gcv or ncv. Gross calorific value (GCV) that is Higher Heating Value (HCV) is the amount of heat that complete combustion releases by burning a unit of fuel....

All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substance is directly related to its mass. ...
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
The ability to calculate average mass is required of students in the physical, natural and social sciences as well as in mathematics. In atomic chemistry, it is sometimes necessary to use the average mass equation to calculate the average mass of a group
