Answer:
D
Explanation:
The statement in the question above gives the statement of the law of conservation of matter. The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.
This particular law is talking about the indestructible nature of matter. Whatever form of matter we have presently was as a result of the fact that it was converted to from one initial form. It is this fundamental law that guides the operation of a wide number of scientific operations. Things like reaction between substances to form entirely or partially new substances are guided by these fundamental laws of nature
The number of valence electrons in will be 26.
The atom's outermost inhabited shell is where valence electrons are found. They are significant because they have a major impact on how an atom's chemical characteristics are determined.
The number of valence electron in P in 5 and number of valence electron in Cl is 7. There are one molecule of P and three molecule of Cl in molecule. By adding all valence electrons , the total number of valance electrons will be 26.
The Lewis structure of is shown as:
Therefore, the number of valence electrons in will be 26.

the mass spectrum is the graphical representation of the ion abundance versus the mass to charge of the ions separated in mass spectrometer
I believe it is a compound, seeing as compounds are basically different types of elements, only combined into one single compound. Please tell me if i'm wrong?
Answer:
2.05 atm
Explanation:
The pressure exerted by a force is equal to the rate between the force exerted and the area over which the force is exerted:
where
p is the pressure
F is the force
A is the area
In this problem, we have the pressure written as
First, we need to convert this into SI units (Newton over squared meters, which is Pascal).
We have:
1 lb = 4.45 N
So the pressure converted into SI units is
Now we know that 1 atmosphere is equivalent to
So we can convert this pressure into atmospheres:
