Answer:
Alkaline earth metals
Explanation:
Group 2 has 2 valence electrons that they lose when being ionized, thus making their charge 2+.
The molecular formula is a chemical formula which indicates the exact number of atoms present in the molecule.
The given molecular formula is and the name of this molecule is propane consist of three carbon atoms which are linked with eight hydrogen atoms by single bonds.
Now, the figure 1 shows the condensed structural formula, figure 2 shows the structural formula and figure 3 shows the skeletal structural formula of propane.
Answer:
18.01528
Explanation:
find this by adding the molecular masses of two hydrogen atoms and oxygen atom
Answer:
1 molecule of chlorine has 2 atoms since it's diatomic.
