I believe that the answer would be A. Tree
(Plus I took the assessment like this sooo, Im 100% this is correct)
Fentanyl is an opoid used for the pain medication together with other medications for anesthesia. It is illegally used as recreation drug as it is mixed with heroine and cocaine. The side effects of this fentanyl include vomiting, constipation, sedation, decreased breathing, hallucinations etc. Fentanyl does not have any hydrogen bonds instead it has nitrogen bonds associated with benzene ring. It does not form molecules within its molecules but forms hydrogen bonds with the water molecule. The nitrogen and the oxygen present forms bonds with the hydrogen of the water molecule. As it forms hydrogen bonds with water it is soluble in water.
Answer:
See explanation
Explanation:
In this question, we have to remember that in all combustion reactions we will have <u>Oxygen</u> as reactive (
) and the products are <u>Carbon dioxide</u> (
) and <u>Water</u> (
). Additionally, for the states, we will have (l) for the <u>liquid state</u> and (g) for the <u>gas state</u>. So, we can analyze each reaction:
<u>Part A.</u>
The formula for nonane is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:

<u>Part B.</u>
The formula for 2-methylbutane is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:

<u>Part C.</u>
The formula for 3-ethyltoluene is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:

See figure 1 for further explanations.
I hope it helps!
Scientist use synapomophies, or shared derived characters, to define cladograms. For instance, mammary glands are a shared characteristic of mammals. All mammals and their oldest common ancestor, had or have mammary glands.Thus, if we are looking at an unidentified animal and trying to place it in a cladogram, if it has mammary glands we know it belongs in that branch. Cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
