CH3 is a methyl radical, which is formed by removing the hydrogen atom from methane, so the hybridization is SP^3
I believe you would just put a 2 in front of NH3 and keep the other ones as 1
A. Covalent bonds is the answer
The answer would be D. The only minerals harder than corundum is diamond.
When using ion-selective electrodes, to compensate for a complex or unknown matrix, the standard addition method can be used to determine the analyte concentration. Option D
<h3>What are ion-selective electrodes?</h3>
Analytical chemistry is a science that deal with the measurement and detection of the accurate amount of a substance. Analytical chemistry plays a large role in environmental management as it helps in the determination of the levels of contaminants in a sample.
An ion selective electrode is used in analytical chemistry to measure the amount of a target ion by converting its activity into a measurable electrical signal.
Hence, when using ion-selective electrodes, to compensate for a complex or unknown matrix, the standard addition method can be used to determine the analyte concentration.
