Answer:
Photosynthesis
Explanation:
Carbon cycle involves the exchange of components between the hydrosphere, biosphere and atmosphere. During carbon cycle, materials such as gases, minerals which are necessary for life are interchange. For example, animals pass out faeces on the soil which is rich in urea. Urea decomposes to provide nitrogen into the soil through bioactive bacterials. The nitrogen is used up by plants to grow. During photosynthesis, plants uses carbon dioxide and water to produce glucose and release oxygen for animals to use. It's like a purification system where one waste product from one organism is used by the other to survive.
Equation of photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
Answer:
Chemical energy
Explanation:
An atom is the basic unit of a chemical element.
A chemical bond held together with atoms, ions, or molecules that leads to the formation of chemical compounds. A chemical bond may be covalent, polar covalent, or ionic. Among these chemical bonds, an ionic bond is the strongest chemical bond.
Chemical energy is stored in the chemical bonds between atoms.
Well partly yes because air pollution can happen when we burn fossil fuels, it can happen when we use vehicles and household/farming chemicals can cause air pollution so yes it is caused by humans
In order to balance this, you have to count each
element where the elements in the reactants side and the product side should
have equal number of molecules. The balanced reaction is as follows:
2HCl + Ca(OH)2 = CaCl2 + 2H2O
