The expression caco3 → cao + co2 is an example of a reactant. product. chemical equation. chemical progression.

The expression is an example of chemical reaction.

Explanation:

Given expression,

This is the chemical equation.

We know that,

In this equation, is the reactant and is the product.

The substance initially present in the chemical reaction is called reactant and the substance formed by the reaction is called product.

Hence, The expression is an example of chemical reaction.

By definition, the expression CaCO₃ → CaO + CO₂ is an example of a chemical equation.

A chemical reaction is any process in which at least the atoms, molecules, or ions of one substance are changed into atoms, molecules, or ions of another chemical substance.

A chemical equation is a symbolic description used to describe the identities and relative quantities of the reactants and products involved in a chemical reaction.

The information contained in the chemical equation allows us to determine the substances that are transformed or modified in a reaction, called reactants or reagents, and the new substances that originate in a chemical reaction, called products.

In order to represent what happens in a chemical reaction by means of an equation, it must comply with the Law of conservation of matter and with the Law of conservation of energy. That is, the equation must indicate that the number of atoms of the reactants and products is equal on both sides of the reaction and that the charges are also equal. In other words, you must have a balanced equation.

Finally, the expression CaCO₃ → CaO + CO₂ is an example of a chemical equation.

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
