Automobile catalytic Converters use a platinum callus to reduce air pollution by changing emissions such as carbon monoxide CO2
natka813 [3]

Answer:

14 mol O₂

Explanation:

The reaction between CO and O₂ is the following:

CO + O₂ → CO₂

We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:

2CO + O₂ → 2CO₂

As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:

28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

Can someone plz help me with this because I do not understand it ASP
AlladinOne [14]

Answer:

I'm not the best at chemistry but from what I remember you need to balance the equation and you need the arrows. It wants you to use double displacement and so thats the definition im assuming.

Explanation:

An example would be

Na2SO4 + SrCl2 --> 2 NaCl + SrSO4

This is a balanced equation.

This link will help you balance an equation.

Hopefully this helps I appologize if it doesn't.

The hierarchy of species is mainly used by taxonomist in order to classify, organize and systematize certain species in both the animal and plant kingdom so to speak –living things. These helps them if found a new discovered specie, they cluster it into the appropriate category into where it fits best. There are certain factors to categorize though.
