chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.

<h3><u>Answer;</u></h3>
They are anions.
<h3><u>Explanation</u>;</h3>
- Polyatomic ions are the ions that contain 2 or more different atoms that are covalently bonded to each other.
- Examples include; Nitrate : NO₃⁻, Sulfate : SO₄²⁻,Hydroxide : OH⁻, and Phosphate : PO₄³⁻, etc.
- Polyatomic ions are tightly bound group of atoms that has a positive or negative charge and behaves as a unit.
Answer:
C. Between North and West
Explanation:
Since all have equal masses and the red ball and green ball are moving in south and east direction, the blue ball would most likely be moving between the north and West direction.
It'd be A. Picture one shows a chemical change. Rust is made from the iron reacting with oxygen.
