What are the pros and cons of chemical energy?
What Are the Disadvantages of Chemical Energy?It isn’t a sustainable form of energy.
It can be expensive.
Some forms of chemical energy are quite rare.
It can produce harmful waste.
It can be used to create devastating weapons.
It offers short-term benefits for long-term consequences..
Why are chemical reactions important in everyday life?
Chemical reactions are how new forms of matter are made. While nuclear reactions also may produce new matter, nearly all the substances you encounter in daily life are the result of chemical changes. Chemical reactions help us understand the properties of matter.
What is an everyday chemical reaction?
Chemical reactions are common in daily life, but you may not recognize them. Look for signs of a reaction. Chemical reactions often involve color changes, temperature changes, gas production, or precipitant formation. Simple examples of everyday reactions include digestion, combustion, and cooking.
What are some real life examples of decomposition reactions?
Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

What are disadvantages of chemical energy?
List of Disadvantages of Chemical EnergyIt can be harmful to the environment. … It comes with a high cost. … It can produce radioactive waste. … It is non-renewable. … It is not good for human health.
What is the importance of chemical equation?
Chemical equation is defined as the simpler or short form representation of a chemical reaction. … Balancing of chemical equation is to maintain equality of number of moles, atoms and mass on both sides (reactant and product sides) of the equation for the reaction.
