What is the TOTAL ionic equations for the following? Ca(ClO)2(aq) + 4HCl(aq) --> CaCl2(aq) + 2H2O(l) + 2Cl2(g)

SrBr2(aq) + K2SO4 (aq) --> SrSO4 (s) + 2 KBr (aq)

2 Cr(NO3)3 (aq) + 3 FeSO4 (aq) --> 3 Fe(NO3)2 (aq) + Cr2(SO4)3 (aq)

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

b. is the answer hoped i        

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
