Answer:
Explanation:
Skeleton equations are also known as unbalanced equations.
Eg I react Oxygen, Hydrogen and Chlorine and I get Water and Chlorine Gas
H2 + Cl2 = HCl
Left Side
H = 2
Cl = 2
Right Side
H = 1
Cl = 1
As you can see it's not balanced is skeleton equation.

Answer;
D, Xe (g)
Solution and explanation;
If 2g has a volume of 340ml.
Density is 1000/340*2 = 5.88g/litre.
-This rules out the two solids, choices 2) &3)
If 1 litre has mass 5.88g,
then 22.4 liters (volume at STP) has mass 5.88*22.4 = 131.8g/mol
molar mass Br2 = 80*2 = 160g/mol NO
molar mass Xe = 131.3g/mol = YES.
Answer is Xe
Answer:
oxygen ion.
An oxygen ion has 8 protons and 10 electrons.
