Explanation:
water evaporates because when h2o (water) particles heat up, they gain energy causing them to start to vibrate. this moves the oarticles further and further away from eachother and making the substance less dense, and turning it into a gas. meaning it has evaporated
Calcium Chloride would have a charge of +2
Hopes this helps :)
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.
Do you have a picture of a diagram?
