Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid. The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0.1oC. The melting point of solid oxygen, for example, is -218.4o<span>C.</span>
I think the answer is the number of protons.
Answer:H2 + F2 → 2HF
Hydrogen react with fluorine to produce hydrogen fluoride.
When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.
Answer:
0.153M
Explanation:
57.3/97.994 (molar mass)=0.585 moles of H3PO4
.0585/3.820L=0.153M
