. The speed of a sound in air is 343 m/s. The sound wave has a frequency of 436 HZ and its period is 0.0023 s. What is the wavelength of the sound?​

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.)
