Give TWO examples of energy conversion that produces unwanted forms of energy.
34kurt

For example, consider the energy used by an electric fan. The amount of electrical energy used is greater than the kinetic energy of the moving fan blades. Because energy is always conserved, some of the electrical energy flowing into the fan's motor is obviously changed into unusable or unwanted forms.

For the reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decoxide and sulfur dioxi
Rainbow [258]

1 mole of  reacts with 8 moles of  to form 1 mole of  and 3 moles of

<h3>What is a tetraphosphorus decoxide?</h3>

Tetraphosphorus decoxide, () is a non-metal oxide that gives acidic property when dissolved in water.

The name phosphorus decoxide can be interpreted as 4 phosphorus (P) atoms (‘Tetra’), bonds with 10 oxygen (O) atoms (‘Dec’) in a molecule. besides that, it is also known as phosphorus pentoxide.

It can be prepared by heating pure phosphorus with oxygen in blast furnace.

+  →

It is used as a dehydrating agent due to its week van der Waals dispersion forces. Thus, owing to give exothermic reaction when dissolved in watermore precisely, it is a white crystalline anhydrous (without water molecule) solid.

In granular form it can be also used as desiccant as well.
