A covalent bond is a bond between 2 non metals, they share electrons. Ionic bonding occurs between a metal and a non-metal, and they transfer electrons.
First you have to know what the space-filling model is. The space-filling model is a model used to show the structure of the atoms. It specially shows the relative sizes of the atoms and how the space between atoms (inside the molecule) is filled. It does not show the angles and lengths of the bonds. So,<span> the disadvantage of using a space-filling model to show a chemical compound is that it will not permit to observe neither the angles nor the lengths of the bonds in the molecule.</span><span />
Answer:
Argon
Explanation:
Given data
We can find the molar mass (M) of the gas using the ideal gas equation.
P × V = n × R × T
P × V = m/M × R × T
M = m × R × T/P × V
M = 27.1 g × (0.08206 atm.L/mol.K) × 449 K/ 0.500 atm × 50.0 L
M = 39.9 g/mol
If the gas is monoatomic, the one with a molar mass of 39.9 g/mol is argon.
