Answer:

2.71 × 10^24 molecules

Explanation:

We are given;

Moles of CO₂ as 4.5 moles

We are required to determine the number of molecules

From the Avogadro's constant;

1 mole of a molecular compound contains 6.022 × 10^23 molecules

Therefore;

Molecules of CO₂ = Moles of CO₂ × Avogadro's constant

That is;  

               = 4.5 moles × 6.022 × 10^23 molecules/mole

               = 2.71 × 10^24 molecules

Hence, 4.5 moles of CO₂ contains 2.71 × 10^24 molecules

Look at the equation for the reaction for nitric oxide and oxygen. Do you think this is a single-step reaction or a multistep re
Sveta_85 [38]

Answer:

This is most likely a multi-stepped reaction.

Explanation:

From the collision theory, we know that it is super improbable for 3 different molecules (2 NO and 1 O2) to all hit each other at the perfect speed in the perfect position to make the products. From this, we can pretty confidently say that this is most likely a multi-stepped reaction.

Hope this helps! :)
