According to picture below, answer is d.c4h2n2o4 and c2hno2.
Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this case C₄H₂N₂O₄). Molecular formula shows that compound has four carbon, two hydrogen, two nitrogen and four oxygen atoms.
Empirical formula gives the proportions of the elements present in a compund but not the actual numbers or arrangement of atoms. C : H : N : O = 2 : 1 : 1 :2.

QUESTION 3 Consider a solution containing 0.80 M NaF and 0.80 M HF. Calculate the moles of HF and the concentration of HF after
Lisa [10]

Answer:

0.056moles HF and 0.70M

Explanation:

When a strong acid is added to a buffer, the acid reacts with the conjugate base.

In the system, NaF and HF, weak acid is HF and conjugate base is NaF. The reaction of NaF with HCl (Strong acid) is:

NaF + HCl → HF + NaCl

Initial moles of NaF and HF in 60.0mL of solution are:

NaF:

0.0600L × (0.80mol / L)= 0.048 moles NaF

HF:

0.0600L × (0.80mol / L)= 0.048 moles HF

Then, the added moles of HCl are:

0.0200L × (0.40mol / L) = 0.008 moles HCl.

Thus, after the reaction, moles of HF produced are 0.008 moles + the initial 0.048moles of HF, moles of HF are:

<em>0.056moles HF</em>

<em></em>

In 20.0mL + 60.0mL = 80.0mL = 0.0800L, molarity of HF is:

0.056mol HF / 0.0800L = <em>0.70M</em>
