Answer:
Temperature stays constant.
Explanation:
During a phase change, the temperature does not change. Temperature will only change when a phase change is completed.
All of them are important to identify a mineral and get information from it, but I'd say the least important is cleavage.
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.
That would be 0.5 g/ml because Density is equal to mass divided by volume and 8.5 is half of 17.
