Answer:
D
Explanation:
This question is a little strange. C and D are very similar, but I would pick D.
Fluorine actually has the highest electronegativity of all the elements. This allows it to pull more electrons towards itself. Since electrons have a negative charge, this causes the fluorine end of the molecule to be more negative while the hydrogen is left striped of electrons and has it positively charged necleus exposed. This means that one end of the molecule is positive while the other is negative, which makes this molecule polar. The only reason I would pick D over C is that D addresses the second part of the question about the covalent bond. A covalent bond is simply when two atoms share electrons.
Let me know if this was right and I hope it helps.

Answer:
yield = 8501.96 g H3PO4
Explanation:
2344.44 g H20 × (1 mol H2O/18.01528 g H20)
= 130.14 mol H20
130.14 mol H2O × (4 mol H3PO4/6 mol H2O)
= 86.76 mol H3PO4
86.76 mol H3PO4 × (97.994 g H3PO4/1 mol H3PO4)
= 8501.96 g H3PO4

Why is there no reaction between silver and copper (II) nitrate?</h3>
For the reaction to occur, it is necessary that the metal which replaces the metal from the compound LIES above that metal in the ELECTROCHEMICAL SERIES(ECS). The metal in the compound here is Copper (II) nitrate where as the metal trying to displace is silver. Silver lies below the copper in a ECS, that means Copper is more reactive than silver. The reaction is not possible because more reactive metal displaces less reactive metal from its compound, and silver is LESS reactive than copper so it cant displace the copper from copper nitrate.
