Explanation:
Write a balanced equation, ionic equation and the net ionic equation for the following:
A) Li2SO4 + Sr(NO3)3 --->
B) H2SO4 + Na2CO3 --->
You made a typo: that's Sr(NO3)2
Molecular:
Li2SO4(aq) + Sr(NO3)2(aq) ==> SrSO4(s) + 2LiNO3(aq)
ionic:
2Li^+(aq) + SO4^2-(aq) + Sr^2+(aq) + 2 NO3^-(aq) ==> SrSO4(s) + 2Li^+(aq) + 2NO3^-(aq)
NET ionic:
Just cancel the ions common to both sides to leave you with
Sr^2+(aq) + SO4^2-(aq) ==> SrSO4(s)
Answer:
8.15 L I2
Explanation:
<u>So, I have the balanced equation of</u>: 2CuBr2 +4KI → 2CuI + 4KBr + I2
<u>Now, we do</u>:
241.6g / 1 mol KI / 1 mol I2 / 22.4 L
--------------------------------------------------------- = 8.15 L I2
/ 166g KI / 4 mol KI / 1 mol I2
Hope this helps! ^u^
