is there a heap t storing seven distinct elements such that a preorder traversal of t yields the elements of t in sorted order? how about an inorder traversal? how about a postorder traversal?
Yes, there is a heap t storing seven distinct elements such that a preorder traversal of t yields the elements of t in sorted order. However, in inorder traversal and postorder traversal, there is no heap t storing seven distinct elements.
In a binary tree system, preorder traversal is used to make a duplicate of the tree. It is also utilized to obtain the prefix expression.
If there is a (min-heap) TT storing seven distinct elements such that a preorder traversal of TT yields the elements of TT in sorted order;
Then, the image attached below shows the description of the preorder traversal in sorted order.
In an inorder traversal, the parent is always listed after its left child. However, in a (min-heap), the parent is usually smaller than the left child. As such, the smaller parent is normally listed after its left child. Hence, inorder traversal of a (min-heap) is not usually sorted in order.
The same scenario for inorder traversal is true for postorder traversal, thus postorder traversal of a (min-heap) is not usually sorted in order.

A coefficient serves which purpose in a chemical equation?
The coefficient indicates the number of molecules in what seems like a mathematical theorem or formula. A more comprehensive explanation follows.
Coefficients seem to be quantities, integers as well as words that are added in front of the same biochemical representation or expression just to counterbalance chemical formulas.The function of coefficients together in balanced chemical would be to represent the proportion wherein the starting materials mix during a reaction.
Thus above response is right.

How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 2.72 x 10⁹ km?
The time taken for the radio signal to reach the earth is 9.1 x 10^3 seconds.
Let us recall that radio waves are part of the electromagnetic spectrum. This means that they travel with the speed of light.
The speed of the wave of obtained from the relation;
Speed = Distance/Time
Therefore;
Time = Distance/Speed
Distance = 2.72 x 10⁹ km or 2.72 x 10^12 m
Speed = 3 x 10^8 m/s
Time taken = 2.72 x 10^12 m/3 x 10^8 m/s
= 9.1 x 10^3 seconds.

What orbital does the quantum numbers n=4 l=2 ml=2 describe
Answer:
Orbital designation
for Principle Quantum number n=4, this is the shell number & corresponds to N shell, (shells are designated K,L,M,N)
for Angular Momentum number l=2, this is the orbital level corresponding to d, given that l can be any integer 0-(n-1), for( 0,1,2,3 )corresponds to (s, p, d, f)
The orbital designation is 4d
for Magnetic Quantum number ml, the suborbitals correspond to -l through l, (-2,-1,0, 1,2)
for ml=-1 the suborbital -1 in the 4d sub shell with electron spin state ms=-1/2
Among the following compounds which are isomers?
I. CH3CH2–0-CH3 II. CH3CH2CH2-OH
II. CH3CH2–0-CH2CH3 IV. CH2=CH-O-CH3
A. I and II
B. I and III
C. II and III
D. I and IV
I and II are the functional isomers of each other. Hence option A is correct.
What is isomer?Isomer is defined as when multiple compounds with the same chemical formula but different chemical structures exist. A prefix that denotes the number of carbons is followed by the suffix -ane, which designates that the molecule is an alkane. By counting the chiral centers in a chemical, one can determine how many optical isomers exist. The formula 2n1, where n is the number of chiral centers, indicates the greatest number of optical isomers.
They are functional isomers because alcohol CH3CH2CH2OH and ether CH3CH2OCH3 contain different functional groups. Functional isomerism, which refers to isomers that differ in the functional group present in the carbon chain, is exemplified by H3-CH2OH and CH3-O-CH3.
Thus, I and II are the functional isomers of each other. Hence option A is correct.

A student uses the periodic table to map out the trend in increasing atomic radii. During peer feedback, a student mentions that her trend is incorrect. Which model and explanation should the student use to help the student understand?
Atomic radius decreases across the period and increases down the group.
The atomic radii is a periodic trend that decreases across the period and increases down the group. Periodic trends are properties of elements that increase or decrease down the group or across the period.
As more positive charges (protons) are added to the nucleus as we move across the period, the attractive force between electrons and protons increases. As such atomic radii decreases across the period.
Down the group, addition of more shells leads to increased electronic repulsion which causes that atomic radii of elements to increases as we move down the group.
