Answer:
0.02 tons of NO produced when 4 tons of coal is burned
Explanation:
From the given,
Chemical formula of coal =
Molecular mass of coal =
Let’s calculate the mass of nitrogen in coal
Amount of coal burnt = 4tons
Amount of NO produced by burning 4tons =
This nitrogen is converted into NO by reacting with atmospheric oxygen.
Answer:
if its a neutral atom there should be 6 electrons because there are 6 protons
Explanation:
To balance the the chemical reaction, the number of moles
per element is balance is both side of the reaction and also the charge in both
sides of the reation. to balnce the reaction:
S2O3 2- + Cu 2+ ---> S4O6 2- + Cu+
2S2O3 2- + Cu 2+ ---> S4O6 2- + Cu+ + e
