7. Calculate the amount of heat(in J) required to increase the temperature of a 22.6 g copper sample from 65.1°C to 92.5°C ? [Specific heat of copper is = 0.337 J/(g°C)]. 8. Consider the reaction: C,H1,O,(8) + 60;(g) → 6CO:(g) + 6H,O(1) , the heat change q for this reaction is –2800 kJ per mole of C,H12O6 that reacts. (i) Is the reaction endothermic or exothermic? (ii) Calculate the heat change when 0.56 mol of C,H1,O, reacts? 9. Calculate the energy and frequency of the light that has the wavelength of 436 nm. (Planck's constant = 6.626 x 104 J.s. ; Speed of light e= 3.00 x 10° m/s.) 10. Place these elements in order of increasing ionization energy. Al, CI, C, Na
