In the burning food snack lab, a student burned a piece of Cheetos that weighs about 2.4 g. She used 75 g of water that absorbed the heat coming from the burning Cheetos. The initial temperature of the water was
26 °C and it rose to 33 °C. How much heat was released by the Cheetos?
Use the formula: Q= mcAT, where m=mass of water, specific heat of water =1 cal/g. °C, AT=
change in Temperature: final minus initial

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
