Solution Steps

Step 1: Understanding the SI Unit System

The International System of Units (SI) is the modern form of the metric system and is the most widely used system of measurement. It defines units for various physical quantities.

Step 2: Identifying the SI Unit of Time

In the SI system, the base unit for measuring time is the "second." Other units like minutes, hours, and days are derived from the second.

Final Answer

The SI unit of time is \(\boxed{\text{A. second}}\).

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements were taken of the amounts of A and B present before and after a reaction that produced some C: Compound initial amount final amount A 1.5 g 0 g B 1.5 g 1.0 g Calculate the theoretical yield of C. Round your answer to the nearest 0.1 g. Suppose the percent yield of C in this reaction was 56%. Calculate the actual amount of C that was isolated at the end of the reaction. Round your answer to the nearest 0.1 g.

Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. Ten pairs of data were taken measuring zinc concentration in bottom water and surface water of a water source. Location Zinc concentration in bottom water Zinc concentration in surface water --------- 1 .430 .415 2 .266 .238 3 .567 .390 4 .531 .410 5 .707 .605 6 .716 .609 7 .651 .632 8 .589 .523 9 .469 .411 10 .723 .612 Do the data support that the zinc concentration is less on the surface than the bottom of the water source, at the alpha=0.1 level of significance? Note: A normal probability plot of difference in zinc concentration between the bottom and surface of water indicates the population could be normal and a boxplot indicated no outliers. a. Express the null and alternative hypotheses in symbolic form for this claim. Assume mud=mu1-mu2, where mu1 is the population mean zinc concentration in the bottom of water and mu2 is the mean zinc concentration in the surface of water. H0: mud Select an answer 0 Ha: mud Select an answer 0 b. What is the significance level? alpha= c. What is the test statistic? Round to 3 decimal places. 20= d. What is the p-value? Round to 4 decimal places. p= e. Make a decision. O Do not reject the null Reject the null f. What is the conclusion? There is sufficient evidence to support the claim that the zinc concentration is less on the surface than the bottom of the water source. There is not sufficient evidence to support the claim that the zinc concentration is less on the surface than the bottom of the water source.
