I'm taking the test right now; I'll edit this when I find out if I was right! (I chose "solvent" but I wanna be sure.)
Edit: Solvent is the correct answer!
I believe the correct answers from the choices listed above are the first two options. The molecules O2- and F2+ are <span>expected to have one unpaired electron. This can be determined by looking at the value of the charge. Hope this answers the question.</span>
Answer:
B) 12.5L
Explanation:
-We apply the mixed Gas Law:
Where:
is the given pressure of the gas
is the volume of the gas
is the number of moles of the gas
is the ideal gas constant and temperature respectively.
#We make V the subject of the formula and substitute to solve for it;
Hence, the volume of the gas is 12.5 L
Answer:
Ionic bonds are opposite, whereas Covalent bonds are opposite.
Explanation:
Two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and othercovalent bonds.
Examples:
Sodium Chloride and Sodium Fluoride are examples of <em>Ionic</em><em> </em><em>bonds</em><em>.</em>
<u>and</u>
Water and Carbon Dioxide are examples of <em>Covalent</em><em> </em><em>bonds</em><em>.</em><em> </em>
