No, its a highly desirable material that is hypothetical, scientifically impossible, extremely rare, costly, or fictional.
In a chemical reaction one or more reactants combine or react to form one or more product(s) with different chemical and physical properties.
When aqueous sodium sulfide reacts with aqueous copper(II) nitrate results in the formation of aqueous sodium nitrate and solid copper(ll) sulfide.
First, identify the chemical symbols for the elements in the compounds.
Sodium sulphide = 
Copper(II) nitrate = 
Sodium nitrate = 
Copper(II) sulfide = 
The chemical reaction is given as:
Now, balance the chemical equation:
For balance the equation, multiply by 2.
Thus,
LET'S PUT IN WHAT WE KNOW!!!

Explanation:
if you removed the C02 from the atmosphere that
willl make the 02 and it will
released for the atmosphere
which means, Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance. Not all organic matter is oxidized. photosynthesis mean if you dont know: Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.
this is why the CO2 is removed and the 02 is released into the atmosphere, Consumers such as animals, fungi, and bacteria get their energy from this excess biomass either while living or dead and decaying. Oxygen from the atmosphere is combined with carbohydrates to liberate the stored energy. ... Photosynthesis removes CO2 from the atmosphere and replaces it with O2.
and if the CO2 is release from the atmosphere this will happen --> Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating CO2 effects the wither, Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts. im sorry that i gave alot of facts my teacher said its good to add alot of facts some of my thoughts thank you i hope you get this right :)
