I use the acronym LEO for oxidation reactions. This stand for: Lose electrons Oxidation, so when oxidation occurs, electrons are lost. Due to electrons having a negative charge, substance undergoing oxidation have a more POSITIVE charge.
Pls Thank + Branliest its good for my ego :P
Answer:
B: Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
Explanation:
We are looking for enthalpy of formation, so we want to see reactance in their natural standard form.
Thus, we want to see the reactance of Na, Cl2 and O2.
The only option that has the correct form of Na, Cl2 and O2 is B.
Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
A welding torch produces a flame by burning of acetylene fuel then energy released from the acetylene fuel is then used to melt a metal, so transformation of chemical energy into thermal energy takes place.
<h3>What is transfer of energy?</h3>
Energy neither can be produced nor destroyed but it only transfers from one form to other form.
In the question it is given that, burning of acetylene produces energy and this produced energy is a type of chemical energy and then this is used as a thermal energy for the melting of metal.
So conversion of kinetic energy to potential energy, thermal energy to electromagnetic energy and potential energy to chemical is wrong.
Hence transformation of chemical energy into thermal energy takes place.
