Concept explainers
(a)
Interpretation:
The products of decomposition reaction of zinc oxide have to be given along the balanced formula equation.
Concept Introduction:
Decomposition reactions: Decomposition reactions are the opposite of a combination reaction because decomposition reaction involves the breaking apart of a substance into simpler substances. Such a reaction is easy to recognize because there is one reactant and more than one product.
Example: The reaction of sodium chlorate to sodium chloride and oxygen is decomposition reaction. The balanced reaction is,
(b)
Interpretation:
The products of decomposition reaction of tin (IV) oxide have to be given along the balanced formula equation.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The products of decomposition reaction of sodium carbonate have to be given along the balanced formula equation.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The products of decomposition reaction of magnesium chlorate have to be given along the balanced formula equation.
Concept Introduction:
Refer to part (a).

- Don't used hand raiting and don't used Ai solutionarrow_forwardWe learned four factors (ARIO) for comparing the relative acidity of compounds. When two of these factors are in competition, the order of priority is the order in which these factors were covered ("atom" being the most important factor and "orbital" being the least important). However, we also mentioned that there are exceptions to this order of priority. Compare the two compounds and identify the exception. OH PK-4.75 SH PK-10.6 5. "Resonance" is more important than "atom" because the conjugate base of first compound is more stable than the second. "Atom" is more important than "resonance" because the conjugate base of first compound is more stable than the second. "Resonance" is more important than "atom" because the conjugate base of second compound is more stable than the first. "Atom" is more important than "resonance" because the conjugate base of second compound is more stable than the first.arrow_forwardThe relative fitnesses of three genotypes are WA/A= 1.0, WA/a = 0.7, and Wa/a = 0.3.

- Explain why this data led Rayleigh to look for and to discover Ar.arrow_forward5) Confidence interval. Berglund and Wichardt investigated the quantitative determination of Cr in high-alloy steels using a potentiometric titration of Cr(VI). Before the titration, samples of the steel were dissolved in acid and the chromium oxidized to Cr(VI) using peroxydisulfate. Shown here are the results (as %w/w Cr) for the analysis of a reference steel. 16.968, 16.922, 16.840, 16.883, 16.887, 16.977, 16.857, 16.728 Calculate the mean, the standard deviation, and the 95% confidence interval about the mean.
