Answer:
≈194.7
Explanation:
(547cm^3/590K) / (V2/210K)
V2 = 194.69 or 194.7

Answer:
Balanced reaction: ![4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O](https://tex.z-dn.net/?f=4Zn%2B10HNO_%7B3%7D%5Crightarrow%204Zn%28NO_%7B3%7D%29_%7B2%7D%2BN_%7B2%7DO%2B5H_%7B2%7DO)
The mole ratio (4 moles Zn/5 moles
) is correct.
Explanation:
Oxidation: ![Zn\rightarrow Zn(NO_{3})_{2}](https://tex.z-dn.net/?f=Zn%5Crightarrow%20Zn%28NO_%7B3%7D%29_%7B2%7D)
Balance N and O: ![Zn+2NO_{3}^{-}\rightarrow Zn(NO_{3})_{2}](https://tex.z-dn.net/?f=Zn%2B2NO_%7B3%7D%5E%7B-%7D%5Crightarrow%20Zn%28NO_%7B3%7D%29_%7B2%7D)
Balance charge:
................(1)
Reduction: ![HNO_{3}\rightarrow N_{2}O](https://tex.z-dn.net/?f=HNO_%7B3%7D%5Crightarrow%20N_%7B2%7DO)
Balance N: ![2HNO_{3}\rightarrow N_{2}O](https://tex.z-dn.net/?f=2HNO_%7B3%7D%5Crightarrow%20N_%7B2%7DO)
Balance H and O: ![2HNO_{3}+8H^{+}\rightarrow N_{2}O+5H_{2}O](https://tex.z-dn.net/?f=2HNO_%7B3%7D%2B8H%5E%7B%2B%7D%5Crightarrow%20N_%7B2%7DO%2B5H_%7B2%7DO)
Balance charge:
............. (2)
[
Equation-(1)] + [Equation-(2)]:
![4Zn+8NO_{3}^{-}+2HNO_{3}+8H^{+}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O](https://tex.z-dn.net/?f=4Zn%2B8NO_%7B3%7D%5E%7B-%7D%2B2HNO_%7B3%7D%2B8H%5E%7B%2B%7D%5Crightarrow%204Zn%28NO_%7B3%7D%29_%7B2%7D%2BN_%7B2%7DO%2B5H_%7B2%7DO)
![\Rightarrow 4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O](https://tex.z-dn.net/?f=%5CRightarrow%204Zn%2B10HNO_%7B3%7D%5Crightarrow%204Zn%28NO_%7B3%7D%29_%7B2%7D%2BN_%7B2%7DO%2B5H_%7B2%7DO)
So, balanced reaction: ![4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O](https://tex.z-dn.net/?f=4Zn%2B10HNO_%7B3%7D%5Crightarrow%204Zn%28NO_%7B3%7D%29_%7B2%7D%2BN_%7B2%7DO%2B5H_%7B2%7DO)
Hence the mole ratio (4 moles Zn/5 moles
) is correct.
Answer:
Most things, if not all, are dependent on the Sun. The Sun causes things to grow, which causes animals to thrive, which causes other animals to thrive, which causes a balanced ecosystem, meaning a balanced food chain.
