What is the percent yield of oxygen in 2kclo3—-> 2kcl+

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.)

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3
