<span>The molar mass of the Formaldehyde is about 30 gram per mol which means it goes like 90/30 =3.
So, the molecular formula would be 3 times the empirical formula. C3H6O3.</span>
This was clear chemical reaction. The Potassium Chlorate reacted with Oxygen in a combustion reaction to change the chemical structure so that it was able to react with Silver Nitrate.
The statement that is correct about wind turbines is that they transform wind energy to electrical energy.
The kinetic energy of the winds will ultimately provide electrical energy! It's a great way for sustainability!
