Answer:
FeS + O2 - Fe,02 + SO2
Explanation:
You have to see that no of Atoms are equal on both sides or not.
FeS + O2 - Fe,02 + SO2
Ferrous is balanced on both sides and also sulphur but oxygen is not balanced .
Ino left side oxygen is 2 while on right it's 4.
So, we have to balanced Oxygen.
FeS + 2O2 - Fe,02 + SO2
Now see it's balanced (we insert 2 on left side to balance the oxygen)
I believe it would be wood burning because you would not be able to reverse that process.
Answer:
The space shuttle was the result of committee compromise and political expediency. It was never the best design. It takes off like a rocket (and blows up like one on occasion) and lands like a plane (or rather, it lands like a brick with control surfaces).
Explanation:
Answer:
The De Broglie wavelength decreases when the momentum increases
Explanation:
The De Broglie wavelength of a particle (or any object) is given by
where
h is the Planck constant
p is the momentum of the object
As we can see, the wavelength is inversely proportional to the momentum of the object: therefore we can say that, if the momentum increases, the De Broglie wavelength will decrease.
When cooled by liquid nitrogen, the balloon shrinks (not as much as the air-filled balloon) and it sinks down on the table. When heating up, the balloon slowly rises and flies up in the air again. Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down.
