What’s the correct order it goes in

Answer:

11 moles

Explanation:

From the coefficients of the equation, we know that for every 3 moles of CuO consumed, 1 mole of nitrogen is produced.

So, the answer is 32/3 = 11 moles to 2 sf.

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.

Explanation:

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

Answer:

5.1316 x10^2

Explanation:

just simply move the decimal point to the first number, and then count how many numbers are after the decimal point

Answer:

5.1316x10^2

Explanation:

move the decimal left until the number is 1-10(not including ten) and count how many places you moved for the exponent, in this case it’s 2

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.

I and II are the functional isomers of each other. Hence option A is correct.

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.
