Why are alkali metals volatile?
The alkali metals are the group 1 metals, lithium, sodium, potassium etc. There is only one valence electron involved in the metallic bond and therefore the bond is weaker. In comparison to the majority other metals they are generally low melting and have low boiling points. As an example sodium melts at about 98 C and boils at 883 C. The relatively low boiling point is an indication of their relatively low volatility. Note that volatility is normally a term associated with very low boiling point substances such as acetone, boiling point 56 C
Why ethyl alcohol and water cannot be separated into pure components by fractional distillation?
Due to an effect called the aziotropic effect. Some of the water remains bound to the ethanol raising the BP and getting dragged over with it. The same thing happens with sugars from a wash. Further to this, ethanol is hygroscopic so it will absorb water from the atmosphere when exposed. The best you can do is between 90 - 98% ethanol.
What city is 29 degrees latitude 98 degrees longitude?
The coordinates 29 degrees latitude and 98 degrees longitude point to the city of Houston, Texas in the United States.
What is -175 C on the Kelvin scale?
The answer is 98.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.-175 deg C = -175 + 273.15 = 98.15 K
What is the atomic structure of californium?

What is the boiling point for N-propanol?
The boiling point of n-propanol is approximately 97.2 degrees Celsius (207 degrees Fahrenheit).
Can water boils at 98 degree celsius?
Water boils at 100 degrees Celsius at standard atmospheric pressure. However, the boiling point of water can be influenced by factors such as altitude and pressure.
Is water at 98 degrees considered hot or boiling?
At 98 degrees Celsius, water is very close to boiling (100 degrees Celsius). For most purposes that's close enough.
Is 98. 6 body temperature in celsius or Fahrenheit?
It is Fahrenheit because the boiling point of water is 100 degrees Celsius
What is inks boiling point?
98 degrees F
Which organic compound has a boiling-point range of between 94-98 degrees?
The organic compound that falls within the boiling point range of 94-98 degrees Celsius is ethanol. Ethanol is a common alcohol that is used in beverages, fuel, and other industrial applications.
Does sea water boil at 98 degrees Celsius?
The boiling point of seawater varies with the level of salt it contains. On average, sea water at sea level will boil at around 103 degrees Celsius.
Why is it wrong to say that water boils at 100 degrees Celsius?
The boiling point of water depends on any additional chemicals that might be in it, and on the atmospheric pressure. PURE water boils at 100 degrees Celsius at "standard" sea-level pressure of 29.92 inches of mercury.
What is the boiling point of 2-butanol?
2-butanol, also known as sec-butanol has a boiling point range from 98 to 100 degrees Celsius. The melting point is set at -115 degrees Celsius.
What is the melting point and boiling point of fountain pen ink?
your pregnant!
Is sodium melts at 98 C a physical property?
Yes, the melting point of sodium at 98°C is a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as melting point, boiling point, and density.
What is the boiling temperature of rubber?
It can not reach a boiling point because it decomposes before it boils.
