Of the six commonly recycled plastics, four can withstand temperatures of 100 degrees Celsius (212 degrees Fahrenheit) or above. According to Machinist Materials, polyethylene terephthalate -- PET, or recyclable 1 -- has a melting point of 255 degrees Celsius (491 degrees Fahrenheit).
Answer:
Salt's ions and sugar's polar bonds are both attracted to the polar water molecules.
Explanation:
Water is regarded as a universal solvent because of its ability to dissolve more substances than any other liquid. This unique property of water is attributed to its POLAR NATURE. Water is a polar molecule and hence, most if not all polar substances will dissolve in it.
Although salt and sugar are substances that have different types of chemical bonding in their structure but they both dissolve in water. This is because they are both polar substances and hence, their polar charges are attracted to the polar molecules of water. This attraction causes an interaction and subsequently dissolution.
The formula of this is : MV = MV or Molarity × Volume = Molarity × Volume. So you do:
25X = 18×.205=.1476M
Answer:
Solids 1 and 3
Explanation:
Their melting points are almost identical and each element has a unique melting point.
