In his laboratory, he set the jar containing the aqua regia and gold solution on a shelf. Like and share true or false questions and answers. The Nazis believed that because the jar matched the appearance of hundreds of other jars in the lab, all of the jars contained typical chemicals. De Hevesy went back to the lab after the war, where he discovered the jar containing the solution and took the gold out of it. The Nobel Foundation used the gold to create new medals for Laue and Franck after he gave the gold back to the Royal Swedish Academy of Sciences.
Scientific analysis and metal etching both employ aqua regia. Additionally, it is used to remove minute metal particles from some laboratory equipment. In particular, it is employed in the extraction and purification of platinum and gold. Compare true or false questions and answers. To prevent it from deteriorating, it is mixed right before usage.

Macedonia’s ruler at the time was Philip II. His performance in the League of Corinth was outstanding. The representatives of all the Greek kingdoms (save Sparta) and the islands took oaths to uphold the general peace (koin eirn) and to acknowledge Philip as its president (hgemn) when the so-called League of Corinth, founded by Philip in 337, was officially launched. Bookmark true or false questions and answers. A political invention of the Greeks themselves, general peace has been employed multiple times in the last 50 years to try to stabilize the situation while advancing one hegemonic power or another. The main Greek states lacked both the strength and the mutual trust necessary to establish a successful organization for taking coordinated action against aggressors, so the peace had never lasted for very long.
In the event that the peace was broken or endangered, Philip created a council of delegates from all the states, known as the Synedrion, which had the authority to discuss and decide on the appropriate course of action. Philip served as the hgemn after the judgments had been taken and before their execution. States were required to meet quotas equivalent to their council voting strength in order to provide soldiers or ships to the hgemn as needed. Explore true or false questions and answers. The fact that the hgemn had Macedonia’s authority in his hands made this organization successful even though neither Philip nor Macedonia had representation on the council. The fact that Corinth, where the initial assembly was placed, was one of only three Greek cities to hold a Macedonian garrison must have been missed by anybody.
In his latter years, Philip II Philip was undoubtedly right to build on the basis of the prior practice of the Greeks themselves and to forgo uniting them in any kind of long-term partnership that would have brought back too many unpleasant memories of the past. However, since he was the king of the Macedonians and not a Greek politician or even a Greek, he was unable to view the establishment of Greece as the pinnacle of his life’s work, as most contemporary historians do. For him, it had no point of culmination and wasn’t even a means to an end; it was just a means. Share true or false questions and answers The Greeks needed to maintain their order since Chaeronea had brought them to it and his ambitions called for it. His plan for a Persian war was heard by the synedrion in Corinth, which suitably praised it early in 337. Early the next year, a Macedonian army advance force entered Asia Minor. At this time, the Greeks would accompany Philip as he led the large army toward Asia.
