The answer is Chemical
Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.
AXz
Explanation:
It is a chemical notation of nuclide
Here X is the symbol of the element
A is the mass number of element
A=n+p(sum of protons and neutrons)
Z is the atomic number.
For example, 12C6
Hers X is C, symbol of carbon
12 is the mass number and 6 is the atomic number of the carbon.
A calorimeter is just an insulated container which contains the sample. You combust the sample inside the calorimeter, then you measure the temperature with respect to time. Make sure to stir constantly. Thus, you need a thermometer and a stirrer. The coffee cup calorimeter is labelled as shown in the picture attached. The goal of this experiment is to determine the specific heat capacity.
