The the last one, but isn't it c6h12o6?
Answer:
Fluorine
Explanation:
These particles stick in the atoms and make them radioactive.
Answer:
0.16 moles of Carbon
Explanation:
The balanced reaction equation:
+
→
+
↑
The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)
i.e 3 moles of C produces 4 moles of Fe.
If 1 mole of Fe - 55.8g of Fe
? moles - 11.6g of Fe
=
= 0.208 moles
But 3 moles of C - 4 moles of Fe
? moles of C - 0.208 moles of Fe
=
= 0.16 moles of carbon.
I hope this explanation was clear and useful.
Answer:
About 25 kPa
Explanation:
Pressure decreases with height above sea level.
The calculation is rather complicated, so I will refer to the figure below.
It shows that the pressure at 10 km is about 25 kPa.
Answer:
Pressure
Explanation:
Apply the definition of pressure to this problem.
