Automobile catalytic converters use a platinum catalyst to reduce air pollution by changing emissions such as carbon monoxide, CO(g), into carbon dioxide, CO2(g). The uncatalyzed reaction is represented by the balanced equation below.2CO(g) O2(g) 2CO2(g) +heat. determine the mass of O2(g) required to completely react with 784g moles of CO(g) during this reaction.

448 g of will be required to completely react with 784g moles of CO(g) during this reaction.

Explanation:

To calculate the moles :

The balanced chemical equation is:

According to stoichiometry :

2 moles of require  = 1 mole of

Thus 28 moles of will require=  of

Mass of

Thus 448g of will be required to completely react with 784g moles of CO(g) during this reaction.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
