Relative atomic mass: c-12, h-1, o-16, ca-40, n-14
Volume I (45 points)
1. The choice question (only one option for each question, 2 x 15 = 30)
1. The composition of combustible ice may be expressed as: CH4 (H2O) n by study: 1m3 combustible ice can be released
Lets put 200 m3 of methane gas, and the following statement is false
A, combustible ice is A high combustion value, and pollution of small B, combustible ice will become the new energy
C, flammable ice can be used as an energy source, indicating that water can be variable
D. There may be combustible ice in the seafloor and permafrost.
The following statement lacks scientific basis
A, wasps, ants, stings, skin is swollen with the action of the formic acid (HCOOH), and applying dilute ammonia or soapy water will relieve the symptoms
B. Surgical instruments can be cooked in high temperature or used for sterilization with 75% alcohol
C, add the right amount of lime to fuel coal, and reduce the emission of SO2 when burning
D, fluorocarbon (CCl2F2) NOx will destroy the ozone layer, leading to the greenhouse effect.
3. There are four isomers of monochlorinated toluene, and the final product of toluene and overdose H2 catalysis, the number of isomers of one chlorinated substance is
A, 3 B, 4 C, 5 D, 6
4. Chemical workers from the reaction: C2H6 (air) + Cl2 (gas) - C2H5Cl (liquid) + HCl (qi) were heuristic, and the way to obtain the by-product hydrochloric acid from pesticide and synthetic industry was proposed. This assumption is becoming a reality, pointing out that the best way to separate hydrochloric acid from these products is ().
A, distillation method B, water washing extraction method C, water bath separation method D, sublimation method
5. In the following solution, the ai
