A. Potassium oxide
B. Calcium chloride
C. Magnesium nitride
D. Sodium hypochlorite
E. Potassium nitrate
Answer:
97.44 K
Explanation:
to answer this one you should use the ideal gas law PV=nRT where P=pressure, V=volume, n=number of moles of gas, R=universal gas constant (0.0821), and T=temperature in Kelvin. All you have to do is substitute the givens into the equation.
(3.10)(16)=(6.20)(0.0821)(T)
then simplify
49.6=(.50902)(T)
divide to get T alone and you get about 97.44 K as your answer
Fluorine and Nitrogen are both non-metals which posses non polar covalent bonds. So in this case, only KCl has polar covalent bond.
Before solving, let us understand the meaning of covalent and ionic bonds and how to identify them.
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Therefore, the polar covalent bond is shown by KCl as it shows sharing of equal electrons amongst them.
