Answer:
SO2 in the atmosphere is due to burning of sulphur containing fossil fuel, S+O2→SO2 and
from smelting and roasting of sulphides.
CuFeS2+O2→Cu2O+FeO+SO2
SO2 content can be controlled by using alternate source of energy for burning, as nuclear energy , solar energy , hydroelectric energy.
Fuels containing sulphur are desulphonated before burning by FGD (fuel Gas Desulphuristion).
If H2O under high pressure is used , it will dissolve SO2 and will lower pH of the soil and thus fertillity is decreased.
Explanation:
Answer:
The reaction is not balanced.
Explanation:
The reaction expression is given as:
4NH₃ + 5O₂ → 4NO + 5H₂O
In a balanced reaction equation, the number of atoms on both sides of the expression is the same.
Now let us investigate;
Elements N H O
Reactants 4 12 10
Products 4 10 9
We see that the number of H and O on both sides of the expression is not the same. The reaction is not balanced.
Answer:
Measurements have shown that the concentration of salt in seawater is 35.5 g-L. Calculate the volume in liters of seawater that must be evaporated to recover 0.400 kg of salt. Be sure your answer has the correct number of significant digits
Water takes longer to cool down and heat up because it detains temperature longer. So in the summer, coastal areas are cooler and the in the winter, coastal ares are warmer.
Answer:
Following are the solution to these question:
Explanation:
Simple diffusion implies which molecules can move across a cell membrane instead of using the incorporated protein structure channels. Its flow of molecules across these canals is enabled by diffusion. It has steroid hormones and N2.
Facilitated diffusion of molecules via cell membranes, or active transportation, which would be the random mass transit process of molecules or ions via unique cellular membranes from the transmembrane. It has K+ and Glucose.
