- What do you mean by degradation of energy? Explain it by taking one example of your daily life.Yazid wants to make compost from leaves, sawdust, and food scraps. Leaves have 2% N, C:N 22.5, and MC 77%. Sawdust has 30% C, C:N 300, and MC 20%, whereas food scraps have 2% N, C:N 20, and 50% MC. If the amount of leaves used is 15 kg, determine how much food scraps and sawdust should be added to get a compost mixture with an ideal ratio of C:N 30:1 and moisture content 60%?Hydrogen sulfide is an impurity in natural gas that must beremoved. One common removal method is called the Clausprocess, which relies on the reaction:8 H2S1g2 + 4 O21g2¡S81l2 + 8 H2O1g2Under optimal conditions the Claus process gives 98% yield of S8from H2S. If you started with 30.0 g of H2S and 50.0 g of O2, howmany grams of S8 would be produced, assuming 98% yield?
- What kind of energy is necessary to initiate the process of photosynthesis?Plants grow in many different shapes and sizes. Much of their shape depends on an internal structure that is composed of carbon-containing molecules such as cellulose and lignin. Plants that have a strong internal structure can grow larger than other plants because their structure can support their size. Plants obtain the majority of the carbon necessary for building these structural molecules from - O air O microorganisms O soil O water 10 11 12 13 14 15 16 17 18 19 20 近(a) Construct a table showing the macrostates and all of the individual microstates for tossing 6 coins.
