Hydrogen carbonate (bicarbonate) is HCO₃⁻. Its Lewis structure has carbon at the center with three oxygens: one OH group, one double-bonded O, and one singly bonded O⁻; the negative charge is delocalized between the two non‑OH oxygens via resonance.

This question needs more information to provide a complete answer. Missing Details Specify: Which models should be included (e.g., linear, quadratic, exponential, logarithmic, power, logistic)? Provide data: Do you have specific (x, y) data points to fit these models, or should I use illustrative examples? Goal: Are you solving for model parameters (e.g., m, b; […]
A linear function can be written in the form y = mx + b. Key Concepts Concept: Form y = mx + b Concept: Slope m is constant Concept: No x^2 or xy terms Steps Action: Look for x^1 terms only Action: Solve for y to reveal mx + b Action: Check no higher powers […]
