Phosphorous is the answer.
To balance chemical equations, what must be done is the same number of each element in the input must be present in the output. For example, photosynthesis.
H2O + CO2 —> C6H12O6 + O2
As can be deduced, the input only has 2 H, 1 C, and 3 O. Whereas, the output has 6 C, 12H, and 6 O. When balancing I recommend to balance the unique elements if possible (for example, H is only in one molecule on each side)
So you get 6(H2O) + 6(CO2) —> C6H12O6 + 6(O2)
Hope this helped!
Answer:
There are two explanations to this: covalent network bonding and carbon-silicate cycle.
Explanation:
A network solid or covalent network solid is a chemical compound which is formed through a continued network of atoms or molecules held together by a covalent bond throughout the system. An example included C-C bond in graphite or C-Si bond in silicon carbide (tentative reaction equation below):
xSiO2 + yCO2→ SixCyO(2x+2y)
Si-Si bonds are not as strong as C-C bonds and can easily be displaced as the particles react with atmospheric CO2.
The second scenerio is when silicates such as calcium silicate CaSiO3, or wollastonite, reacts with atmospheric carbon dioxide and water to yield a calcium ion, Ca2+, a bicarbonate ion, HCO3-, and dissolved silica. This process occurs during carbon-silicate cycle and increase organic carbon content:
2CO2 + H2) + CaSiO3 → + SiO2CaCO3 + CO2 + H2)
