There are also cases when a negative change in entropy can lead to a spontaneous reaction. According to this equation, if the free energy, G, of the system is negative, then the reaction is spontaneous.

Answer:

Each element has unique physical properties such as density, melting point, boiling point, etc. These properties can be used to identify an element using a reference book that contains such information about each element. Flame tests, atomic spectra, and spectroscopy can be used to identify some elements.

If 5.85 moles of CaCO3 are used in an experiment, how many moles of carbon dioxide are created? (Be sure to include units in you

azamat

Answer:

5.85 moles of carbon dioxide are created.

Explanation:

The balanced reaction is:

CaCO₃ → CaO + CO₂

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

CaCO₃: 1 mole
CaO: 1 mole
CO₂: 1 mole

Then you can apply the following rule of three: if by stoichiometry 1 mole of CaCO₃ produces 1 mole of CO₂, 5.85 moles of CaCO₃ will produce how many moles of CO₂?

$moles of CO_{2}=\frac{5.85 moles of CaCO_{3} *1mole of CO_{2} }{1 mole of CaCO_{3}}$
