Air is made up of different gases, such as oxygen, nitrogen, and car
tia_tia [17]

The correct option would be that oxygen, nitrogen, and carbon dioxide cannot react with one another.

<h3>Why air components cannot react</h3>

The components of atmospheric air, nitrogen, oxygen, carbon dioxide, etc., cannot react with one another because there is not enough energy in the atmosphere to set the reaction rolling.

For a reaction to take place, there must be enough energy to break the bonds in each air component. This is why the air components will not spontaneously react with one another, except during special events such as lightning and thunder.

If the CaCO3 weighed 983 g and the CaO weighed 551 g, how many grams of CO2 were formed in the reaction?
stira [4]

Answer:

The answer to your question is 432 g of CO₂

Explanation:

Data

CaCO₃  = 983 g

CaO = 551 g

CO₂ = ?

Balanced reaction

                               CaCO₃ (s)   ⇒   CaO (s)   +  CO₂ (g)

This reaction is balanced, to solve this problem just remember the Lavoisier Law of conservation of mass that states that the mass of the reactants is equal to the mass of the products.

                    Mass of reactants = Mass of products

                    Mass of CaCO₃   = Mass of CaO + Mass of CO₂

Solve for CO₂

                    Mass of CO₂  = Mass of CaCO₃ - Mass of CaO                    

                     Mass of CO₂ = 983 g - 551 g

Simplification

                     Mass of CO₂ = 432 g

Andrej [43]

Answer:

6. C3H2O

Explanation:

C= 12.0107; H= 1.00797; O=15.9994

We calculate:

C= 65.85/12.01=5.48

H= 4.91/1.00=4.91

O=29.24/16.00= 1.82

Later, we divide among the smaller quantity

C=5.48/1.82= 3.01

H=4.91/1.82= 2.70

O=1.82/1.82=1
