5. Draw conclusions: What is the relationship between the object density, the liquid density, and the tendency of the object to float?

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.)

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.
