When heated kclo3 decomposes into kcl and o2 (> 2kcl+3o2 )if this reaction produced 31.9 g of kcl, how much o2 was produced in grams

12 grams of oxygen

Explanation:

To calculate the moles, we use the equation:

For

Given mass = 31.9 g

Molar mass of   = 122.5 g/mol

Putting values in above equation, we get:

2 moles of produces 3 moles of

0.26 moles of produces = moles of

Mass of

Thus 12 grams of oxygen was produced.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
