Answer:
2.0 l
Explanation:
When for 20 °C volume is 1 l then for 40°C is going to be 2 l
20-------1
40-------x
x=(40*1):20
Answer:
Bond order is a counting method that gives an idea about numbers of electrons shared between atoms. A species with a higher bond order is more stable. A bond order equal to 2 is a double bond, and a bond order of 3 is a triple bond.
Explanation:
Answer:
The statement is considered to be true
Explanation:
The statement is true because when elements chemically combine, there are interactions between their valence electrons, causing the two elements to be bonded together to form what is known as a compound.
Compounds can only be formed from interactions between two or more elements. examples include:
Hydrogen + Oxygen = H2O (water)
Sodium + Chlorine = NaCl
Note that if atoms of the same element combine, what is formed is a molecule, not a compound. Some atoms usually do this to attain stability. examples include = O2 H2 and N2. They are oxygen molecule, hydrogen molecule, and nitrogen molecule respectively.
Compounds are only formed when different elements combine to attain electronic stability.

Answer:
I think #3 might be the answer .
Because in #1 atomic mass tells mass .
#4 Atomic number doesnot only tell about the electrons atom has
