(a)
Interpretation:
The appropriate formula for hydroxylamine should be determined.
Concept introduction:
All known compounds are mainly classified as ionic and covalent compounds. In the naming of ionic compounds, the name of cation always comes first then the name of anion will come. In the naming of covalent compounds, the name of center atom will come first followed by other atoms with certain suffix that depends on the charge and atoms. In case of writing the formula, same rules need to follow such as writing the cation symbol first then anion symbol will come in ionic compounds. The criss-cross method must be used to balance the charges on cation and anions. In order to write the covalent compounds, write the
(b)

The appropriate formula for calcium hydrogen phosphate should be determined.

- There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
