Answer:
D. Separating a salt solution by evaporating the water
Explanation:
B. Allowing a nail to rust is a chemical change.
Becuase once the nail rust it turns into flakes and therefore is no longer a nail.
C. building a model rocket propelled by mixing baking soda and vinegar
By mixing baking soda (a powder) into vinegar ( a Acid) it causes a explosion...
the baking soda dissolve into the acid.... This a chemical reaction
A.creating salt by reacting sodium metal and chlorine gas
Sodium is salt but it says.... Sodium metal..... chlorine gas Changes color and it has a strong odor... chlorine gas with sodium metal turns it into salt.... it doesnt stay a metal or a gas it CHANGES.....
so therefore its a Chemical change
When A object or substance changes form or it causes a exsplosion or reaction it is a chemical change.
D. Separating a salt solution by evaporating the water
For a physical change your object may change color or shape but its still the same object.
salt in water ... The salt dont dissolve it just salty water.
So seperating salt by evaporating the water is a physical change.
<u>Switch the 3 and the 4</u>, this change must made to the coefficients to balance this equation.
Now, the correct balance equation is C₃H₈ + 5 O₂ → 3 CO₂ + 4H₂O
This method of balancing chemical equations involves assigning algebraic variables as stoichiometric coefficients to each species in the unbalanced chemical equation.

Answer: The amino acid sequence is Leu-Ser-Val
Explanation: To produce amino acids, the DNA has to "transform" itself into a RNA by a process called Transcription. In this process, part of the DNA is transcribed into a similar RNA. The RNA produced undergoes another process, called Translation. From it, the sequence is decoded to a specific polypetide, as shown in this case. In the Translation, each 3 bases corresnpond to 1 amino acid. Because of it, the sequence above has 3 amino acids.
The N-terminal and C-terminal relates to the part where the sequence start to be read and the end of the process. Normally, the sequence starts at the 5', which correspond to the N-terminal and finishes at the 3', which matches the C-terminal. So in this example, the DNA template read 5\'GACAGACAA 3\'.
Explanation:
Because it’s a energy drink but does have high sugar additives.
