Answer:
It is incorrect because sodium phosphate is a compound that has a single composition.
Explanation:
Sodium phosphate is a compound and not a mixture. It is made up of sodium and phosphate ions and they exists as just a single compound and not different entities.
The parts of a mixture exists separately and they retain their identities.
- In the compound a sodium phosphate we have 3 atoms, Na, P and Oxygen joined together in a definite grouping.
- The properties of the compound are different from the individual elements that makes them up.
Coal releases carbon dioxide when burned. The reaction looks like this:
C(s)+O₂(g)→CO₂(g)
I hope this helps. Let me know in the comments if anything is unclear.
Hello.
balance the equation first
<span>Cu + 2AgNO3 ----> [2Ag] + Cu(NO3)2
</span>
<span>Now set up the equation </span>
<span>350gCu*(1molCu/ 63.546g Cu) * (2molAg/1molCu) * (107.8682g Ag/1molAg)
</span>
<span>Cancel out 1molCu with 1molCu, and cancel out 2molAg with 1molAg (it still remains 2mol Ag) </span>
<span>You are left with </span>
<span>350gCu*(1/63.546g Cu)*(2Ag/1)* (107.8682g Ag/1)
</span>
<span>350gCu*1*2*107.8682= 75507.74g
</span>
<span>now divide 75507.74g by 63.546g
</span>
<span>you get [1188.2374972460896g Ag]
</span>
Have a nice day
