(a)
Interpretation:
The number of significant digits in the following has to be stated.
Concept introduction:
Measurements are done with the help of an instrument. The instrument is usually calibrated. In a measurement the uncertainty is expressed in terms of significant digits. The rules to determine significant digits are as follows
• All digits that are non-zero are significant.
• Zeroes to the left of the non- zero digit are not significant.
• The zeroes between two non-zero digits are significant.
• The digits to the right side of a non-zero digit are significant only if they lie after a decimal point.
(b)

- All of these compounds would be produced (I think). In my book, I don't see any rules about yield in this case, like explaining that one product would be present in less yield for this reason or that reason. Please explain why some of these produce less yield than others.arrow_forward5. Fill in the missing molecules in the following reaction pathway.

- Help with a periodic table task.' Procedure Part 1: Customizing a Periodic Table Use a textbook or other valid source to determine which elements are metals, nonmetals, metalloids (called semimetals in some texts), alkali metals, alkaline earth metals, transition metals, halogens, and noble gases. Download and print a copy of the Periodic Table of Elements. Use colored pencils, colorful highlighters, or computer drawing tools to devise a schematic for designating each of the following on the periodic table: Group numbers Period number Labels for these groups: alkali metals, alkaline earth metals, transition metals, inner transition metals (lanthanides and actinides), other metals, metalloids (semimetals), other nonmetals, halogens, and noble gases Metals, nonmetals, and metalloids Note: Write the group and period numbers and color/highlight each element for categorization. Be sure to include a key for the schematic.
