Answer:
Option D. 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe
Explanation:
The balanced equation for the reaction is given below:
3CO + Fe₂O₃ → 2Fe + 3CO₂
Molar Mass of Fe = 56g/mol
From the balanced equation above,
3 moles of CO2 produced (2 mol Fe x 55.845g Fe.
Therefore, 0.9 mole of CO2 will produce = 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe
Answer:
The metal strip on the left has a lower activity than the one on the right.

Twice as much more will the freezing point of water be lowered in beaker a than in beaker b.
<h3>What determines freezing point?</h3>
A liquid's freezing point rises if the intermolecular interactions between its molecules are strong. The freezing point, however, drops if the molecules of inter - molecular are minimal. The process through which a substance transforms from a liquid into a solid is known as freezing.
<h3>How significant is freezing point?</h3>
Freezing points play a big role in occupational safety. A chemical may perhaps turn harmful if held below its freezing point. A critical safety benchmark for assessing the effects of worker exposure to cold environments is the freezing point.

IV. Molasses will sink because it has a greater density. The rest will float or suspend.
