The option that accurately reflects the trend regarding electron affinity is the second choice: it typically becomes more negative as you move across a period."<span> Electron affinity represents the energy that a neutral atom either absorbs or releases upon gaining an electron. A more negative value indicates a stronger attraction of the atom for an extra electron. Thus, as electronegativity increases across a period, which shows how much more strongly atoms on the left side draw electrons, the observation that electron affinity becomes more negative across a period suggests that atoms on the left have a greater tendency to accept an additional electron.</span>
Explanation:
Lewis-dot structure: It illustrates how the atoms in a molecule are bonded together and indicates the presence of unpaired electrons in the molecule.
The molecule in question is, 
Carbon possesses '4' valence electrons, hydrogen has '1' valence electron, and chlorine contains '7' valence electrons.
Consequently, the cumulative count of valence electrons in = 1(1) + 1(4) + 3(7) = 26
Based on the electron-dot structure, there are 8 bonding electrons and 18 non-bonding electrons.
The electron-dot representation for is depicted below.
Next, we need to assess the formal charges on carbon, hydrogen, and chlorine.
The formula for calculating formal charge:
B is identified as an ionic compound. Explanation: This conclusion is drawn based on the characteristics of ionic compounds, which typically form crystals similar to salt (sodium chloride), are soluble in water, exhibit high boiling and melting points, possess hardness from strong intermolecular forces, and can conduct electricity—though only when dissolved or in a molten state.
They overcomplicated things with lots of words. Your initial equation deals with the revenue. I’ll denote tacos as x and burritos as y.
The first equation would be 3x + 7.25y = 595, given that you already have the prices but need the quantities. The second equation will reflect that double the burritos were sold compared to tacos, expressed as y = x + 2.
Hope this clarifies things. If you need further explanation, I can elaborate more.
