Calcula la entalpía para la reacción siguiente: Sn (S) + Cl2 (g) > SnCl2 (S)

A partir de la información que se proporciona a continuación:

Sn (S) + 2Cl2 (g) > SnCl4 (S) ∆H°reacción =-545,2 Kj

SnCl2 (S) + Cl2 (g) > SnCl4 (l) ∆H°reacción =-195,4 K

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

What reaction is taking place? 02 + c3h8 = h20 + co2

Stage in which a star’s outer layers have started to cool and grow outward?
