Answer:

lost

Explanation:

When a television set changes electrical energy to sound and light energy, some of the initial energy is lost in other forms usually heat.

Energy conversion or transformation from one form to another is not an 100% efficient process. This is compliance with the law of thermodynamics.

  • The process of transforming energy brings about some loss of energy into the environment.
  • No system is 100% efficient in transforming all the energy input into it.
  • Some of the energy is usually lost in the process of conversion.

Calcium forms ions with a charge of +2. Iodine forms ions with a charge of -1. Which of the following would represent an ionic c
astra-53 [7]

 The   formula that would represent an ionic  compound  that is composed of calcium and iodide ions  is   CaI2

 Explanation

Ionic compound  CaI₂ is formed  when Calcium form cation ( <em>a positively charged ion</em>) by losing 2 electrons while two iodine atoms form  anion ( <em>a negatively charged ion</em>)  by  gaining one electron each.

When writing down   formula of ionic compound, the formula  of cation  is written  first followed by anion  formula. therefore  Ca is written  first  followed by I.

The numeric subscript 2 after I(iodine) indicate that 2 atoms of iodine are involved  in bonding.
