The answer is b because of the atmosphere and it’s gasses it makes the nail rust
Chemical formula of compound describes and shows the number of atoms of each element that are present in a compound.
As in tyrosine number of atoms are:
hydrogen = H = 11
carbon = C = 9
oxygen = O = 3
nitrogen = N = 1
So the chemical formula will be:
C₉H₁₁NO₃
In writing chemical formula of organic compound, we write carbon first then hydrogen and then the other atoms.
The balanced reaction is
3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2
To balance this reaction of double displacement, we see first that this reaction maintain the valence numbers of every atom.
Then, to have the same value of Na in the two sides of the reaction we multiply for the number of the other side. So,
(Na3PO4)x 2
(Na2SO4)x3
As we can see either, we need to balance PO4 cause there are two molecules of this in the reactant side, so we have two molecules of PO4 in the product either.
Then we get
3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2
To probe that balance was correct, you can verify that the charges are exactly the opposite.
Answer:
This is what I think it is, correct me if I'm wrong. Answer is stated below:
Explanation:
Destructive Interference
Two waves combine to form a wave with a smaller amplitude than either the original wave. Destructive interference can occur when the crest of one wave overlaps the trough of another wave. If the crest has a larger amplitude than the trough of the other wave, a part of it remains.
The best and most correct answer among the choices provided by your question is the third choice or letter C.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when "<span> gases cycle up and down based on air pressure."
