Answer: I'm not sure what answer to give you since there are no answer choices, but here is what I got.
Explanation:
Mg is a reducing agent, Fe 2O 3 is an oxidizing agent.
Igniting a mixture of Fe2O3 and Al with a magnesium ribbon fuse produces molten iron and aluminum oxide in an impressive exothermic reaction.

The answers is: 375 moles NaOH
Answer:
0.7 moles of Chlorine gas is required.
Explanation:
The reaction is balanced as follows:
2Na + 
------> 2NaCl
According to stoichiometry,
2 mole Sodium reacts with 1 mole Chlorine gas
∴1 mole Sodium reacts with 1/2 moles of Chlorine gas
∴1.4 mole sodium reacts with 1.4/2 moles of Chlorine gas
= 0.7 moles of Chlorine gas
So, 0.7 moles of Chlorine gas is required.

Density:
The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.
Density = mass in g / volume in cubic cm or ml
Given that
Density = 8.92 g/ ml
Mass = 40.0 g
Therefore,
Volume = mass/ density
= 40.0 g/ 8.92 g/ ml
= 4.48 ml
Thus the correct answer is 4.48 ml
