It orders the chemical elements in a useful way.
Answer:
the rock layers of the Grand Canyon
Explanation:
Steno's law are laws that applied to sedimentary rocks. These laws helps in understanding sedimentary sequences.
Sedimentary rocks are derived from the deposition of pre-existing rocks in basins. In order to understand some important relationships between these rock layers, Steno's law offer a good insight.
Steno's law are often applied when we want to do relative dating of rock layers. Some of the laws are:
- Law of superposition of strata
- Law of original horizontality
- Law of lateral continuity
- Law of inclusion
- Law of fossil and fauna succession
These laws helps to interpret sedimentary rock sequences better.
Oxygen is a chemical element with symbol O and atomic number 8. Classified as a nonmetal, Oxygen is a gas at room temperature.
Answer:
chemical energy transgormation takes place during cellular respiration
Answer : The type of compound created is Ionic compound and the chemical formula is KCl.
Explanation :
- Potassium has 1 electron in its valence shell and chlorine has 7 electrons in its valence shell.
- The potassium loses 1 valence electron & make a positive charged ion and chlorine picks it up & make a negative charged ion and then they attract to each other.
- Potassium and chlorine atom combine to form potassium chloride by the ionic bonding.
- An ionic compound is made of a metal and non-metal element. And in this case, potassium is a metal element and chlorine is a non-metal element.
The ionic compound formation is,
The Chemical formula is KCl.
