Answer: 27.5 liters
Explanation:
To calculate the moles, we use the equation:
For ![KClO_3](https://tex.z-dn.net/?f=KClO_3)
Given mass = 100.0 g
Molar mass of
= 122.5 g/mol
Putting values in above equation, we get:
![\text{Moles of}KClO_3 =\frac{100}{122.5}=0.82moles](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%7DKClO_3%20%3D%5Cfrac%7B100%7D%7B122.5%7D%3D0.82moles)
![2KClO_3(s)\rightarrow 2KCl(s)+3O_2(g)](https://tex.z-dn.net/?f=2KClO_3%28s%29%5Crightarrow%202KCl%28s%29%2B3O_2%28g%29)
2 moles of
produces 3 moles of ![O_2](https://tex.z-dn.net/?f=O_2)
0.82 moles of
produces =
moles of ![O_2](https://tex.z-dn.net/?f=O_2)
Volume of ![O_2=moles\times {\text {molar volume}}=1.23\times 22.4=27.5L](https://tex.z-dn.net/?f=O_2%3Dmoles%5Ctimes%20%7B%5Ctext%20%7Bmolar%20volume%7D%7D%3D1.23%5Ctimes%2022.4%3D27.5L)
Thus 27.5 liters of
are produced by the complete decomposition of 100.0 g of
at STP
Answer:
c2h4 (etthane........
bexcuse it has 6 bond of hydrogen
Answer:
D.
Explanation:
Im not quite sure if its correct or not
The solid is ice because it has london disperson forces due to electron revolving around nucleus in atom of hydrogen and oxygen
It also has dipole-dipole attraction due to differnce in electronegativity among hydrogen and oxygen atom
It also has hydrogen bonding between oxygen and hydrogen
