A current of 5 mA flows through a 2 mm inner-diameter glass tube filled with 1.0 mol dm-3 NaCl(aq) solution in the anode compartment in addition to a CH3COONa (aq) solution in the cathode compartment. The boundary created between the two solutions moves 6.05 mm towards the anode in 10 minutes. Calculate the transport number of the chloride ion in the solution.

Write a program that takes nouns and forms their plurals on the basis of these rules:
If noun ends in “y”, remove the “y” and add “ies”.
If noun ends in “s”, “ch”, or “sh”, add “es”.
In all other cases, just add “s”.
Print each noun and its plural. Try the following data:

According to the document Consumer Expenditures, a publication of the U.S. Bureau of Labor Statistics, the average consumer unit spent $1749 on apparel and services in 2002. That same year, 25 consumer units in the Northeast had the following normally distributed annual expenditures, in dollars, on apparel and services. At the 5% significance level, do the data provide sufficient evidence to conclude that the 2002 mean annual expenditure on apparel and services for consumer units in the Northeast differed from the national mean of $1749? (Note: The sample mean and sample standard deviation of the data are $1935.76 and $350.90, respectively.) Check the assumptions Hypotheses Sample mean: Sample Std. dev: Sample size: Significance level: P-value = Conclusion: Since P-value is ___________ than the significant level, _________, we ____________ null hypothesis. We have sufficient evidence to say that...
