(a)
Interpretation:
To identify the equality and two conversion factors for a bee flies at an average speed of 3.5 m per second pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(b)
Interpretation:
To identify the equality and two conversion factors for the daily values (DV) of potassium is 4700 mg pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(c)
Interpretation:
To identify the equality and two conversion factors for an automobile travelled 46.0 km on 1 gal of gasoline pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(d)
Interpretation:
To identify the equality and two conversion factors for the pesticide levels in plums was 29 ppb and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(e)
Interpretation:
We have to identify the equality and two conversion factors for each of the pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.

- In the image, the light blue sphere represents a mole of hydrogen atoms, the purple or teal spheres represent a mole of a conjugate base. A light blue sphere by itself is H+. Assuming there is 2.00 L of solution, answer the following: The Ka of the left & right solution is? The pH of the left & right solution is? The acid on the left & right is what kind of acid?arrow_forwardNonearrow_forwardNonearrow_forward
- Nonearrow_forwardWhat spectral features allow you to differentiate the product from the starting material? Use four separate paragraphs for each set of comparisons. You should have one paragraph each devoted to MS, HNMR, CNMR and IR. 2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too. 3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of functional group changes.arrow_forwardQuestion 6 What is the major product of the following Diels-Alder reaction? ?
