What is the melting point of Zinc Metal?
The melting point of zinc is 692.68 K (787.15 �F) 420 C or 419.73 C
When a sample of neon with a volume of 648 mL and a pressure of 0.985 ATM was heated from 16.0 to 63.0 C its volume became 689 mL What was its final pressure in ATM?
Begin with the Equation; P1V1/ T1 = P2V2/ T2 Therefore, (785 torr)(2.00 L) / (37.0 C) = (X)(3.24 L)/ (58.0 C) = 759.59 TORR. To get the answer into ATM, you need to divide the answer in torr by 760. EX. 760torr = 1 atm. 759.59 torr / 760 torr = .999 atm.
What is the chemical symbol for the compound rubbing alcohol?
One is that it is quite flammable. It's not clear what chemical properties you mean however. It is called isopropyl alcohol, isopropanol, or 2-propanol, or propan-2-ol. It's chemical formula is C3H8O As regards its physical properties, it is a clear liquid, with a strong odor. It is also fairly volatile (evaporates easily). It's molar mass is 60.10 g/mole, it's density is .785 g/cm3, its melting point is -89 °C and its boiling point is 82.3 °C.It is completely soluble (miscible) in water, ethanol, ether, acetone and toluene, and slightly soluble in brine,For more information, see the Web Links to the left of this answer.
Which is denser water or alcohol?
Heavier is an inappropriate word. Water is denserthan alcohol; it is not heavier. In your question, you should have written greater: Why is the density of water greater than the density of alcohol? Remember, density is defined as mass per unit volume. Examples are pounds per cubic foot (lb/ft3), kiolgrams per cubic meter (kg/m3), and milligrams per milliliter (mg/ml). You could say that water is heavier per unit volume than alcohol. That is the same as saying water is denser than alcohol. Think of it another way: Although water is denser than alcohol, a gallon of alcohol is heavier than a teaspoon of water. In other words, to determine which is heavier, you must first know how much you're starting with. Now, to answer your question! Water is denser than alcohol because the space between water molecules is less than the space between alcohol molecules. Hence, there is more matter per unit volume of water than per unit volume of alcohol. Since a unit volume of water contains more matter than an identical volume of alcohol, its denisty is greater.
