Answer:
Explanation:
Hello,
In this case, by using the Avogadro's law which allows us to understand the volume-moles behavior as a directly proportional relationship:
We can compute the volume of 34.3 g of argon by representing it in mole as shown below:
Thus, we find:
Best regards.
Answer: ✅
The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure.

Answer:
XY → X + Y general reaction represents a decomposition reaction where a molecule is “broken” in two separate molecules
Explanation:
In a double-displacement reaction two molecules will exchange atoms or group of atoms, and it should look like this:
XY + AB → XA + YB
In a combustion reaction molecules are reacting with oxygen generating oxides.
XY + O → XO + YO
In a single-displacement reaction an atom or a group of atoms in a molecule are replaced by other atoms, and it should look like this:
XY + A → XA + Y
