Given example of the model used in science that is larger than the real object and an example of a model that is smaller than the real object

Is this a single replacement reaction or there is no

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 table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change
