Answer:
No
Explanation:
A single property is not conclusive for identifying a substance. For example, conductivity. Copper, aluminum, and lead all conduct electricity, yet they have different atomic number, electronegativity, and physical properties, thus their shared property of conducting electricity is not enough to correctly identify each substance.
The removal of excess wastes helps in maintaining chemical homeostasis and prevents breaking down of systems that causes a serious health issue.
<u>Explanation:</u>
Human body is composed of many different organ system that are inter related with each other's functions. If the function of one system is disturbed then the function of other system also gets affected resulting in affecting the entire human body functions. The system that is used to remove the excess wastes and unwanted things from the human body is an excretory system. It performs tow major function in a human body. It removes unwanted things and it also helps in draining the broken down components.
The excretory system helps in the control of internal chemical homeostasis. When a living organism's physical and chemical conditions are maintained steadily it is called as homeostasis. This system also helps in maintaining the human systems in a controlled and good condition thereby preventing the failure of other systems and serious health damages.
Answer:
- when the decane is heated it vaporises/turns to a gas
- decane vapour/gas breaks down as it comes into contact with hot porous pot
- large molecules of decane produce smaller molecules, including ethene
Answer:
The answer is The unsorted sand and rock is the least porous.
Average atomic mass of an element is a sum of the product of the isotope mass and its relative abundance.
For example: Chlorine has 2 isotopes with the following abundances
Cl(35): Atomic mass = 34.9688 amu; Abundance = 75.78%
Cl(37): Atomic mass = 36.9659 amu; Abundance = 24.22 %
Average atomic mass of Cl = 34.9688(0.7578) + 36.9659(0.2422) =
= 26.4993 + 8.9531 = 35.4524 amu
Thus, the term “ average atomic mass “ is a <u>weighted</u> average so it is calculated differently from a normal average
