Earth’s crust is made of the earth’s crust and upper mantle. It is subdivided into portions called plates that move above the mantle. The two kinds of crust are oceanic crust, which is thinner but denser than continental crust. The earth’s crust is made of plates moving slowly and interact in various ways in plate

Draw the best Lewis structure for the acetate ion, CH3CO2⁻, including any important resonance structures. What is the formal charge on the terminal double bonded O atom? +2 – 2 0 + 1 – 1 The Correct Answer and Explanation is: To draw the best Lewis structure for the acetate ion, CH₃CO₂⁻, we need to

What is the lewis structure for CH3CO2- ? What is the electron and molecular geometry? Draw the molecular geometry. Is it polar or non- polar? The Correct Answer and Explanation is: The Lewis structure for the acetate ion CH3CO2−\text{CH}_3\text{CO}_2^-CH3​CO2−​ (or CH3COO−\text{CH}_3\text{COO}^-CH3​COO−) is as follows: Step 1: Count the valence electrons. Total valence electrons:4 (C)+3×1 (H)+2×6 (O)+1 (negative charge)=12 electrons.4 \ (\text{C})
