An example of a household endothermic reaction is boiling water. The process of water going from the liquid to gas phase is an endothermic process (you have to put heat into the water).
An example of a household exothermic reaction is the burning of natural gas occurring on a stove-top or in an oven to cook food. The natural gas, mostly methane, CH4, burns by combining with oxygen to from carbon dioxide and water (and some other by-products such as carbon monoxide). This exothermic reaction creates the heat to cook with. Another example is burning wood or coal.
An example of a substance in the liquid phase is water! Some other common examples of liquids are oil, gasoline, rubbing alcohol, and acetone (nail polish remover).
What else can I help you with?
If the mass of all objects before a chemical change is 200kg what would the mass be after the chemical changed occurred?
There will be a gain in mass.....but you can't predict the new change in mass unless you weigh the products after the chemical change occurred.
How do the household cleaners undergo chemical change?
Household cleaners undergo chemical changes when the active ingredients in the cleaners interact with substances they are designed to clean. For example, when a cleaning agent breaks down grease or dirt on a surface, it is undergoing a chemical change. This can result in the formation of new compounds that help effectively clean the surface.
How is physical change and chemical change different?
A physical change is when some thing's shape or volume is changed. But a chemical change is a reaction between two or more objects to create something new and you can't get back what you originally started with.
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax

Can you give me some examples of chemical changes and physical changes involved in the use of household products?
Chemical change examples include: when bleach reacts with dirt on a surface, forming new molecules; when vinegar and baking soda mix, producing carbon dioxide gas. Physical change examples include: when ice melts into water; when detergent dissolves in water.
What household objects are examples of reversable change?
An ice cube melting into water and then refreezing back into an ice cube is an example of reversible change. Another example is heating and cooling certain metals, such as a paperclip, which can be straightened when heated and then reshaped when cooled.
