Concept explainers
Interpretation:
The number of hydrogen atoms attached to each carbon atom in the given molecule has to be counted.
Concept Introduction:
Bond-line drawings are the one where carbon atom and hydrogen atoms are not explicitly shown. Hydrogen atoms bonded to an atom apart from carbon is shown explicitly. These drawings show the information about the carbon skeleton with any
The total number of valence electrons in carbon is four. In Bond-line drawings, the hydrogen atoms connected to the carbon atoms are not shown explicitly. The basic rule to find the total number of hydrogen atoms that is connected to the carbon is found out by counting the number of bonds attached to it: uncharged carbon atoms have a total of four bonds.

What was the color of the hydrate? blue What was the color of the…arrow_forwardcompared t-critical with t-calculated and 95% confidence interval to answer this questionarrow_forwardComparing 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.arrow_forward
- 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?arrow_forwardExplain the difference between the propagated uncertainty and the standard deviation.
