Answer : The final temperature is, 
Explanation :
As we know that,
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
.................(1)
where,
q = heat absorbed or released
= mass of water at 
= 150 g
= mass of water at 
= 100 g
= final temperature = ?
= temperature of lead = 
= temperature of water = 
= same (for water)
Now put all the given values in equation (1), we get
![150\times (T_{final}-363)=-[100\times (T_{final}-303)]](https://tex.z-dn.net/?f=150%5Ctimes%20%28T_%7Bfinal%7D-363%29%3D-%5B100%5Ctimes%20%28T_%7Bfinal%7D-303%29%5D)
Therefore, the final temperature is,
Answer:
3,924°F
Explanation:
here is the answer it is a little hard to explain but hopeing it helps you a lot
The ratio of phosphorous to oxygen is 2:5
<u>Explanation</u>:
- In a compound P2O5, the ratio of phosphorous to oxygen atoms is 2:5. Because there are two phosphorous atoms and five oxygen atoms. Both combined are called a P2O5.
- The elements of phosphorous and oxygen are added to P2O5. So P2O5 is called as phosphorous pentoxide. The element phosphorous will be added to oxygen and it will form a chemical reaction.
- This includes a change in the energy of P2O5. So the new energy will be produced.
