A block of ice of 10 gm at - 10°C is slowly heated and converted to steam at 100°C, calculate amount of heat required to change ice at -10°C to steam at 100°C (specific heat ofice is 0.5 cal/gm°C and latent heat of ice 80 cal/gm and latent heat of vaporization of water is 540 cal/gm and Sw=1cal/gm/°C)​

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

Answer body lying face up ;

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18
