Answer:
1))) When quicklime is added to water, it forms slaked lime along with the evolution of heat. ... Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.
2))) Combustion reactions involve heat and light whereas oxidation reaction does not involve heat. All combustion reactions are oxidizing since they absorb Oxygen for the reaction to take place but all oxidation reactions are not combustion reactions.
3))) Pulmonary artery
4))) Energy is released when bonds form to make carbon dioxide and water. In this case more energy is released than is put in so the reaction is exothermic. ... Burning gas releases heat and warms whatever is around it, so it's exothermic.
5))) HCl secreted by the parietal cells in the stomach converts the environment into acidic. This acidic environment is necessary for the action of the enzyme pepsin.
But the enzymes present in the small intestine acts in the alkaline environment.so,the acidic environment needs to be transformed into the basic one.this function is done by the bile juice.
Presence of the NaHCO3 in bile makes the juice alkaline.
composition of gallbladder bile is 97% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids and lecithin),and 200 meq/l inorganic salts.
These inorganic salts neutralize the pH.
6))) Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen.
7))) sorry but give the diagram of the wires
