If the relative atomic mass of an element R is 32 and the oxide formed by the element R contains 60% oxygen, the chemical formula of the oxide is ____
Let this oxide be R2Ox,16x/(16x+64)=0.6, solve x =6, bring into the equation and get RO3, don't write SO3, do n' t let you guess what the element is

- 15. About the crystal and the melting point We all know that a crystal has a certain melting point. However, people observe that in winter, when the same person is standing on the outdoor ice in ordinary shoes, the ice does not melt, but after wearing the ice shoes, the ice at the blade can melt; a large piece of ice is supported by a bracket, and a thin iron ring is fastened. When a heavy object is hung under the ring, the ice under the iron wire melts into water, and when the iron wire falls behind, the water above can condense into ice. Can you guess one of the reasons?
