Answer:
Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Explanation:
Answer: 2.17mol/L
Explanation:
C=n/V
n: 0.217mol
V: 100.0mL
1. Convert mL to L (100.0mL/1000 = 0.01L)
2. Put numbers into equation (C= 0.217/0.01L)
3. Molarity is 2.17mol/L
Answer:
3) Warm Temperatures and High pressures
Explanation:
This is the typical characteristic of southern air masses moving north
Answer:
5 atoms
Explanation:
According to the law of conservation of mass, "matter is neither created nor destroyed in the cause of a chemical reaction".
We finish with what we start with in a chemical reaction. Although new species might form, the number of atoms on both sides of the expression will still be maintained.
All chemical reactions obey this law of conservation.
