What is the boiling point of chlorine expressed in degrees Farnhight?
The chemical element Chlorine has the atomic number 17 and is denoted by the symbol Cl. The boiling point for Chlorine is -34.04 degrees centigrade or -29.27 degrees Fahrenheit at standard pressure.
If research is restricted then the new discoveries made are limited. Which action would most likely increase the number of discoveries scientists can make?
Increasing government funding of research
What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
How could the lowest melting point of solder be found more accurately?
by using a more accurate thermometer by repeating the measurements between 30% and 50% tin by increasing the number of measurements between 40% and 60% tin by increasing the number of measurements between 50% and 70% tin
Predict the order of increasing boiling points of the noble gases?
The boiling points of noble gases increase with increasing atomic number. Therefore, the order of increasing boiling points is helium < neon < argon < krypton < xenon < radon.
Which solute an electrolyte or a non electrolyte has the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water?
An electrolyte has a greater effect on the boiling point compared to a non-electrolyte when dissolved in water. This is because electrolytes break into ions in solution, increasing the number of particles and thus raising the boiling point more significantly through colligative properties compared to non-electrolytes which do not dissociate into ions.
What are the properties of a colligative property?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure

How does the number of carbon atoms in a hydrocarbon atom affect its boiling point?
The more is the number of carbons in the alkane, the more is its boiling point.REASON:- As the number of carbon increases, the becomes the molecular mass. And the more is the molecular mass, the greater becomes the surface area which increases the van der Waal force of intermolecular attraction thereby increasing the boiling point of the alkane.NOTE:- Among isomers (of the same alkane), the structure which have more # of side chain has less BP because more the # of side chains are present, more will the structure will be closer to the shape of a sphere, therefore will have smaller surface area.-by spd831
The immigration act of 1965 had the effect sharply increasing the number of immigrants from what country?
Asia
How do those properties of Alkanes vary as the number of carbon changes?
As the number of carbons increase, each additional CH2 group contributes to a fairly constant increase in the boiling point and density. The melting point is also increased but to a lesser extent.
What are the hydrocarbons prefix?
The prefixes for naming hydrocarbons are based on the number of carbon atoms in the molecule. They include: meth- (1 carbon), eth- (2 carbons), prop- (3 carbons), but- (4 carbons), pent- (5 carbons), hex- (6 carbons), hept- (7 carbons), oct- (8 carbons), non- (9 carbons), dec- (10 carbons).

How many carbons are there?
Do you have a specific molecule or compound in mind? Without further context, it is not possible to determine the number of carbons.
What is the effect of increasing the number of bytes allocated to the mantissa?
The mantissa holds the bits which represent the number, increasing the number of bytes for the mantissa increases the number of bits for the mantissa and so increases the size of the number which can be accurately held, ie it increases the accuracy of the stored number.
How can one determine the number of carbons on a ring structure?
To determine the number of carbons on a ring structure, count the number of corners or vertices on the structure. Each corner represents a carbon atom in the ring.
