200 mL of a 0.500 M solution of AgNO3 reacts with 200 mL of a 0.500 M solution of HBr in a coffee-cup calorimeter and the temperature rises from 22.80 °C to 26.58 °C. Assuming the density and specific heat of the resulting solution is 1.00 g/mL and 4.184 J/g∙°C, respectfully, what is the ΔH°rxn?

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

the answer is definitely c.

the answer is option a.

5 structural isomers

the isomers are:

n-exane :   ch3ch2ch2ch2ch2ch3

2-methylpentane :   ch3ch(ch3)ch2ch2ch3

3-methylpentane :   ch3ch2ch(ch3)ch2ch3

2,3-dimethylbutane :   (ch3)2chch(ch3)2

2,2-dimethylbutane :   (ch3)3cch2ch3
