1.1 g of CaCI2 dissolved in 50 cm3 of water caused a rise in temperature of 3.4°C. The heat of reaction, ∆H for CaCI2 in kj per mole is?

(Ca = 40, CI = 35.5, specific heat of water is 4.18 jk-1)

The statement "caused a rise in temperature" indicates that heat was given off to the surrounding which is a characteristic of exothermic reactions.

And make them clearer like the spacing and all that.

Thank you so much, you're really trying.🤗
