At stp what is the mass of 44cm3 of carbon dioxide​

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.)

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?
