Examples of chemical reactions in the environment include photosynthesis, where plants convert carbon dioxide and water into oxygen and glucose; rusting of iron, which is a form of oxidation reaction; and acid rain formation due to the reaction of water droplets with sulfur dioxide and nitrogen oxides in the atmosphere.
Of course they do. Some examples are fizzing, when a gas is produced, colour changes, and the formation of precipitates.
Bubbles, and heat change are examples of chemical reactions. When a chemical reaction happens, a compound is formed. It cant be separated. Another example could be change of colour. -making caramel sauce -getting a suntan
Indothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing a decrease in temperature. Energy is required for the reaction to occur, making it endothermic. Examples include the reaction between baking soda and vinegar.

The photosynthesis is an endothermic reaction that takes place everyday.
Calculating the amount of product formed in a chemical reaction, determining the limiting reactant in a reaction, and balancing chemical equations are all examples of stoichiometry.
An oxidizing agent is reduced in a chemical reaction by gaining electrons. Some examples are halogens, nitric acid and potassium nitrate.

Common examples of Gibbs free energy questions in thermodynamics include determining the spontaneity of a reaction, calculating the equilibrium constant of a reaction, and predicting the direction of a chemical reaction under different conditions.

Energy that is stored into something and released by a chemical reaction is known as chemical energy. Some examples of these are batteries, gasoline, coal, and food.
What if the child is 13 yrs old and want to move in with father if you have phyiscal custody of her?
In an endothermic reaction, temperatures decrease because heat is absorbed from the surroundings to drive the reaction. Examples include photosynthesis, the evaporation of water, and the melting of ice.
