Explanation:
The temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure is known as boiling point.
At the boiling point the liquid and vapor state of a substance remains in equilibrium till the time all molecules of liquid do not turn into vapor.
When all the liquid molecules change into vapor state then only there will occur a rise in temperature.
Properties that do not depend on the amount of matter are known as intensive properties.
For example, boiling point, melting point, density etc.
On the other hand, properties which depend on the amount of matter are called extensive properties.
For example, volume, density etc.
Thus, we can conclude that if you heat a liquid and measure the temperature at which it boils, you are measuring an intensive property.
Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.

Explanation:
Sulfur has valence electron 6 and oxygen has 6*3 = 18 valence electrons. In this drawing, you'll see that sulfur violates the octet rule that is it has more than 8 electrons but it is legal since sulfur is in 3rd period, and elements that fall in 3rd period or more in periodic table can use their d orbitals and others to go beyond the normal "8" electrons in valence shell rule which is octet rule
All the formal charges are minimized...that is everything has formal charge of 0 in this structure which is always encouraged.

Answer: ![5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.Explanation:The balanced chemical equation is: [tex]2NH_4NO_3(s)\rightarrow 2MgO(s)+4NO_2(g)+O_2(g)](https://tex.z-dn.net/?f=5.6dm%5E3%5B%2Ftex%5B%20of%20gas%20is%20produced%20when%200.1%20moles%20of%20magnesium%20nitrate%20is%20decomposed.%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EExplanation%3A%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3EThe%20balanced%20chemical%20equation%20is%3A%0A%3C%2Fp%3E%3Cp%3E%5Btex%5D2NH_4NO_3%28s%29%5Crightarrow%202MgO%28s%29%2B4NO_2%28g%29%2BO_2%28g%29)
According to stoichiometry :
2 moles of 
produce = 4 moles of 
gas and 1 mole of 
gas
2 moles of produce = 5 moles of gas
Thus 0.1 mole of produce =
of gas
Volume of gas produced = 
Thus [tex]5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.
