How many moles of kcio3 must completely react to produce 6 moles of o2?

The answer is:

4 moles of are required to produce 6 moles of  

To solve stoichiometric problems, we need to write the balanced equation of the compound that we are working with.

Potassium chlorate decomposition is given by the following equation:

Now, from the equation we know that 3 moles of gives 2 moles of , we can calculate how many moles of the same compound react to produce 6 moles of the following equation:

Hence, we have that 4 moles of are required to produce 6 moles of  

Have a nice day!

your answer would be “dry”

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
