When evaluating a paper delivery, a homeowner would be most concerned about ____. a. the accuracy of the throws c. the speed of the throws b. the precision of the throws d. the acceleration of the throws Please select the best answer from the choices provided
Answers
Answer:
b. the precision of the throws
Explanation:
When dealing with paper delivery homeowners are mainly concerned about the precision of the throws. They technically want the paper to land directly on their front door. Landing there, the paper will be protected from the rain and be visible for the homeowner to easily see it and pick it up in the morning when they wake up. Bad precision can lead the paper to fall into a puddle or on the grass where it will get wet and become useless or even end up breaking a window or other fragile items.
Which region in the ir spectrum could be used to distinguish between butanoic acid and 2-butanone?.
Answers
The region in the IR spectrum could be used to distinguish between butanoic acid and 2-butanone is 2500-3300 cm^-1.
What is IR spectrum:
IR spectroscopy (which is short for infrared spectroscopy) deals with the infrared region of the electromagnetic spectrum, i.e. light having a longer wavelength and a lower frequency than visible light. Infrared Spectroscopy generally refers to the analysis of the interaction of a molecule with infrared light.
The IR spectroscopy concept can generally be analyzed in three ways: by measuring reflection, emission, and absorption. The major use of infrared spectroscopy is to determine the functional groups of molecules, relevant to both organic and inorganic chemistry.
Therefore,
For carboxylic acid, a broad peak for -OH group is obtained in the region of 3000-2500 cm-1 in the IR spectrum. This is the distinguishing feature of -COOH or carboxylic group of butanoic acid and -CO or ketone of butanone. Both shows -CO or carbonyl peak in the region 1680-1750 cm-1, but the above mentioned distinguishes them.

Explain why Ra is larger than Be. With 2 points.
Answers
Explanation:
Radium(Ra)=>atomic number=88
BERYLLIUM (Be)=>atomic number =4
why is Ra larger than Be
1. since the atomic number of Ra is greater than Be, the number of electrons is more, which means there are more number of shells present in Ra than Be. (atomic Radius)2. the more the valence electron (excluding fully filled ones) the less is the nuclear attraction forcesince Ra has more valence electron in its outermost shell, the nuclear attraction force is less which means that Ra 's size is greater than Be.hope it helps:)

The distance between platforms A and F on the zip-line course is provided;
On the path of travel graph shown, we have;
Point B's coordinates are (-25, -20) and Point C's coordinates are (-15, 5)
The formula provides the distance between two locations with coordinates (x1, y1) and (x2, y2);
l=[tex]\sqrt[]{(y2-y1)^2 +(x2-x1)^2}[/tex]
Therefore, by inserting (-25, -20) = (x1, y1) and (-15, 5) = (x2, y2), the distance between B and C may be calculated.
that provides;
l=[tex]\sqrt[]{(5- (-20))^2 + ((-15) - (-25))^2}[/tex] = 26.926 units
B and C are separated by 26.926 units.

a chemist has a block of iron metal (density is 7.87 g/ml). the block weighs 1.90 g. what is the volume of the iron block in ml?
Answers
The block of iron metal with a density of 7.87 g/mL has a volume in mL of 0.2414 mL
The density formula and the procedure we will use is:
ρ = m/v
Where:
v= volumeρ= densitym= massInformation about the problem:
m= 1.90 gρ= 7.87 g /mLv= ?Applying the density formula and clearing the volume (v), we get:
ρ = m/v
v = m / ρ
v = 1.90 g / 7.87 g/ mL
v = 0.2414 mL
