Answer to Problem 89A
A page of this textbook is a heterogeneous mixture.
Explanation of Solution
Mixtures can be categorized as homogeneous or heterogeneous depending on how the components are distributed.
A heterogeneous mixture is one whose composition is not constant throughout.
A mixture is said to be homogenous if its composition is constant throughout.
A solution is another term for a homogeneous mixture.
A page of this textbook is a heterogeneous mixture where the pages are separable from the book.

(3) points) OH OH بر بد بدید 2 3arrow_forwardThere 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).
