95 mL of 0.225 M AgNO3 was mixed with 47.5 mL of 0.225 M CaCl2 in a coffee cup calorimeter. If the reaction started at 23.7 degrees Celsius, what is the final temperature? Assume the specific heat capacity is that of water. Assume the density of the solution is 1.00 g/mL.

Un cierto gas tiene un volumen de 800ml a 80°c y 600ml a 80°c y 600mmhg de presión. ¿cual será el volumen del gas a condiciones normales? sí el gas es oxígeno, ¿cuál será su peso? y ¿cuántas moléculas están presentes en el sistema?

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass
