Ex. 34*. Translate the following sentences into Ukrainian.

1. Had they taken into account the weight before heating they would have made less mistakes. 2. Thus, the deuterium, the nucleus of H² could be considered to be built up from a proton and a neutron. 3. Had the condenser been placed in a direct current the current would have started flowing as though the condenser were not present. 4. Were water allowed to run back into the generator an explosion might result. 5. It is necessary that they should determine whether or not this inorganic substance is contained in the sample to be analyzed. 6. It is necessary that atomic energy should be used only for peaceful purposes. 7. A reliable device for neutron storage could greatly simplify the procedure, so that only one detector would be needed. 8. It is desirable that the determination of the effect of glass composition should be made. 9. If no catalyst were employed in cracking, the process would be called "thermal cracking". 10. If the gas were colourless, we should not notice its formation; we should have noticed the formation of this gas if it hadn't been colourless. 11. If analytical balances were used the results would be much more precise. 12. If air were a single compound the bubbles escaping from the solution would have the same composition as those of undissolved air. 13. If the liquid were placed between the plates of a condenser and an electric field applied, the molecules would tend to orient themselves both to positive and negative plates. 14. Had water been purified carefully they wouldn't repeat the experiment. Remember: water has to be purified lest it should contain microbes. 15. If two liquids had been mutually insoluble, neither one would have lowered the vapour pressure of the other. 16. It is desirable that the sample should be weighed again as the weight does not confirm our data. 17. If a crucible filled with pure arsenic were heated to a temperature above the melting point of the arsenic, and the system were then allowed to cool, it would be noted that the temperature would increase steadily with time. 18. If pure lead were used the falling drops would solidify rather suddenly on reaching the temperature 327°C. 19. If we contemplated water in a glass, the water would appear optically uniform. At any rate, we cannot discern any difference in the appearance of the water at the bottom of the glass and on the surface. 20. If there was no order in the way in which atoms of different elements combine to form the molecules and crystals of compounds, it would be necessary for us to memorize one by one the formulas of thousands of substances. 21. If an electron were to be removed from the sodium atom, leaving only 10 electrons around the nucleus, the resulting particle would have a positive charge, this particle composed of a sodium nucleus and 10 electrons, being called a sodium ion. 22. If the absolute temperature were doubled, the speed of the molecules would increase. 23. If some iodine crystals are put into a flask, which is then stoppered and allowed to stand at room temperature it would soon be seen that the gas in the flask becomes violet in colour, showing that a quantity of iodine evaporated.
