Among the following equations, the equation best representing the given diagram in the problem statement has to be identified. Concept Introduction: Chemical equation is the symbolic representation of a chemical reaction using the symbols of elements. Chemical equation must be balanced on both sides (reactant side and product side) of the reaction. A balanced equation alone obeys the "Law of conservation of mass" Balancing a chemical equation is based on "trial-and-error" method. For each step during balancing of chemical equation, the atoms involved in reaction are listed out. Then the number of atoms on both sides of the reaction (reactant side and product side) is checked for tally. Suitable numerals are placed as coefficients before the element or compound on either side of reaction wherever necessary. Placing of coefficients are allowed for balancing equation, whereas changing the subscripts of elements or compounds are not allowed. Always place coefficients for compounds first rather than placing it for elements. Polyatomic ions can be treated as single unit on both sides rather than considering their constituents individually. While balancing the equation, the numerals used must be simple whole number. To Identify: The best equation representing the given diagram

compared t-critical with t-calculated and 95% confidence interval to answer this question

Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161, 165, 160, 167, 166 1+3 HNO3–HCl: 159, 145, 140, 147, 143, 156 Determine whether there is a significant difference between these methods at the 95% confidence interval.

Comparison of experimental data to “known” value. Monna and co-workers used radioactive isotopes to date sediments from lakes and estuaries.21 To verify this method they analyzed a 208Po standard known to have an activity of 77.5 decays/min, obtaining the following results. 77.09, 75.37, 72.42, 76.84, 77.84, 76.69, 78.03, 74.96, 77.54, 76.09, 81.12, 75.75 Do the results differ from the expected results at the 95% confidence interval?
