commendable b) material c) many .what is antonym of spiritual The Correct Answer and Explanation is: The antonym of spiritual would be material. While the term “spiritual” generally refers to matters relating to the soul, religious beliefs, or non-physical aspects of existence, “material” refers to physical, tangible aspects of life—things that can be seen, touched,

What is the molecular geometry of CO32-? The Correct Answer and Explanation is: The molecular geometry of the carbonate ion (CO₃²⁻) is trigonal planar. Explanation: In summary, the molecular geometry of CO₃²⁻ is trigonal planar with bond angles of about 120°, and it exhibits resonance to stabilize the overall structure.

What is the molecular geometry of theCO₃²⁻   ion The Correct Answer and Explanation is: The correct answer is trigonal planar. Explanation:The carbonate ion (CO₃²⁻) has a trigonal planar molecular geometry. This structure arises because the ion has three bonding pairs of electrons and no lone pairs on the central carbon atom. Here’s how it works:

Pedro’s temperature this morning was 38.1°C. After 2 hours, his temperature was 39.3°C. Did it improve or get worse? How many degrees did his temperature increase? The Correct

There are three known compounds with the molecular formula of C2H2Cl2 but only one with the formula of C2H3Cl. Explain this in terms of molecular structure by drawing the four structures, identify which molecules are polar. The Correct Answer and Explanation is: The molecular formula C2H2Cl2 corresponds to three different compounds due to different structural
