Answer: A) 67.1 moles
Explanation:
The balanced reaction is :
To calculate the moles, we use the equation:
According to stoichiometry;
2 moles of iron is produced by 3 moles of carbon monoxide
89.3 moles of iron is produced by= moles of carbon monoxide
2 moles of carbon monoxide is produced by = 1 mole of oxygen
Thus 134 moles of carbon monoxide is produced by = moles of oxygen

According to the research, the correct option is remove. An air-to-air heat pump removes heat from the outside air and deposits it in the conditioned space.
<h3>What are heat pumps?</h3>
It is characterized by being a thermal machine or a device based on thermodynamics that, through an absorption process, takes heat from one place and transfers it to another, that is, it extracts heat from a cold source to a hot one.
An air-to-air heat pump starts by sucking in outside air or recovers heat from outside and transfers it to a higher temperature level in the ambient air, raising the temperature of the room, being adjustable to adapt to the heating needs of the conditioned space.
Therefore, we can conclude that according to the research, the correct option is remove. An air-to-air heat pump removes heat from the outside air and deposits it in the conditioned space..

I’m pretty sure the answer is
↳ To transport materials throughout the body!
Multicellular organisms need a circulatory system to transport substances to and from their cells!
There you go! I hope this helped, if there’s anything just let me know! ☻
