en un tanque con 15,000 litros de gasolina un químico desea calcular la masa de la misma sustancia si se sabe que la densidad de la gasolina son 700 kg/m³

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
