In the reaction c + o2 co2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. what mass of oxygen
would be needed in the reaction?
18 g
549
729
90g

54 g

C(s) + O₂(g) → CO₂(g)

We are given;

18 g of Carbon

72 g of Carbon dioxide

Therefore;

Mass of Oxygen gas + mass of the carbon = Mass of carbon dioxide

Therefore;

Mass of Oxygen gas = mass of carbon dioxide - mass of carbon

                                  = 72 g - 18 g

                                  = 54 g

Therefore, the mass of Oxygen needed would be 54 g

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

air quality

poor drinking water

and heavy polution

can lead to poor health
