You are given 12.33 moles of o2. how many moles of co2 can be made?

The moles of carbon dioxide gas formed is 12.33 moles.

Explanation:

We are given:

Moles of oxygen gas = 12.33 moles

The chemical equation for the reaction of carbon and oxygen to produce carbon dioxide follows:

By stoichiometry of the reaction;

1 mole of oxygen gas produces 1 mole of carbon dioxide gas.

So, 12.33 moles of oxygen gas will produce = of carbon dioxide gas.

Hence, the moles of carbon dioxide gas formed is 12.33 moles.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
