Translate the sentences into Russian. 1 . The work referred to also brought to light many examples of abnormal behaviour. 2. Having examined it carefully, wc found out that the gas under investigation exhibited anomalous behaviour. 3. The abnormal osmotic pressures can be explained by the hypothesis of a hydrolytic decomposition. 4. To conclude, there arc two features of high abnormal chcmical reactivity. S. If the temperature is raised, a small amount of phenol must be added in order to produce a separation of liquid. 6 . If water is added to ether, solution will not occur. 7. Shown in the following table is the degree of agreement between the two sets of values. 8 . The experimental facts wc obtained arc in agreement with the law. 9. And to sum up, the pressure must be considered in agreement with the modem kinetic theory. 10. If wc prepare some HgCd alloys and allow the alloy to reach the ordinary temperature, it will generally solidify provided enough Cd is present. 11 . Other conditions being equal, the dissociation theory is in good agreement with these observations. 12. The agreement between the final columns shows the hydrolysis of the salt to have practically disappeared. 13. The results of several methods to be described later arc in satisfactory agreement. 14. If a solid be allowed to cool down, it becomes heterogeneous. 15. a- and P-rays were found to consist of pulsations analogous to Rdntgcn rays. 16. Though somewhat different, analogous behaviour may be observed in the case of the gaseous system. 17. It follows from the above that the case is analogous to a mixture of alcohol and water. 18. Returning to van’t H offs argument, it will be remembered that the striking feature of his argument is that he actually calculated the normal constant for substanccs dissolved in a given solvent. 19. To understand Arrhenius’ argument more clcarly, it is ncccssary that wc should refer to the work of Kohlrauch. 20. The gas law has been seen to apply only to dilute solutions. 21. With the help of the kinetic theory applied to the thermal expansion, one can calculate that the absolute zero is -273°C. 22. Applying the law of mass action, the following equation was obtained. 23. The values given below arc calculatcd on the assumption that 1 gram- molcculc of the substancc under examination is dissolved in 10 litres of water. 24. This assumption is shown to be quite inadequate. 25. The formula quoted earlier is based on a number of assumptions which restrict its applicability. 26. It has been shown experimentally that this assumption is 252 a correct one in the inorganic colloids examined. 27. Further assumptions were made about the electrical work required for the vibration of the жүктеу/скачать 5,96 Mb. Достарыңызбен бөлісу:
