explain the following chemical reaction with balanced reaction
Answers
Answer: mark as brainliest if it helps you
a chemical reaction can be described with an equation that shows the formula of each reactant and each product. An equation must be balanced to show that no mass is lost or gained during the reaction. An equation may also show the physical state of each component and the energy change associated with the reaction. For example, a complete equation for the burning of propane, C3H8, is:
C3H8(g) + 5 O2(g) 3 CO2(g) + 4 H2O(l) H = -2220 kJ
The symbols after each formula show the physical state of that substance. The equation can be read as: One molecule of gaseous propane reacts with five molecules of gaseous oxygen to yield three molecules of gaseous carbon dioxide and four molecules of liquid water.
An equation can also be read in terms of moles. This equation states: One mole of gaseous propane reacts with five moles of gaseous oxygen to yield three moles of gaseous carbon dioxide and four moles of liquid water.
The H term following the equation describes the enthalpy change H that accompanies the reaction. For this equation, the enthalpy term states that the combustion of one mole of gaseous propane to gaseous carbon dioxide and liquid water is accompanied by the release of 2220 kJ of energy. We will discuss enthalpy changes accompanying a reaction more thoroughly
