A, because a synthesis reaction is A+B—> AB
B is a decomposition AB—> A+B (opposite of synthesis)
C is acids and base acid 1 + base 1 —> acid 2 + base 2
D is double displacement AB+CD —> AD+CB
Determine the density.
Explanation:
The best procedure a student can use to examine the intensive property of a rectangular block of wood is to determine its density.
An intensive property is a property of matter that is independent of the amount of matter present in it. Examples are density, melting point, boiling point etc.
Every substance in pure form have their distinct density. It is without regards to the mass and volume of such substance present.
Mass, length and volume are extensive properties that depends on amount of matter present.

Answer:
No. It is more dense than the uncrushed bread.
Explanation:
The mass is the same, however the volume has been decreased on the crushed side, forcing more matter into one space, which increases the density.
<span>ionic compounds usually involve a metal and a non metal, and non ionic (or covalent) bonds are usually between 2 non metals
a) Fe3P2 Iron is a metal, Phosphorus is a non metal so it is likely to be non ionic
p.s metals are on the left of the periodic table and non metals on the right</span>
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to infer this problem is about the application of the Gay-Lussac's gas law to relate the initial and final pressure and temperature as shown below:
Thus, solving for the final pressure, P2, and using the temperatures in Kelvins, we obtain:
