What is the boiling point of ethanol at 30.9 in HG?
if you can achieve 30.9 in/hg more power to you.
What does the term polarising power of a cation mean?
Polarizing power: Polarising power is the ability of an atom or group of atoms to attract the shared pair of electrons toward itself. For example: If you have aluminium chloride.... the aluminium ion has a 3+ charge and is relatively small. The chlorine ion has a 1- charge and is larger than the aluminium ion. As a result...the aluminium ion has a higher charge density (i.e. a stronger attraction) and so attracts the shared pair of electrons (between the chlorine and aluminium) towards itself. we say aluminium has high polarising power because of its ability to do this. And the chlorine is easily polarised because the electrons get taken away from it.
Why do transition elements have high polarising power?
Transition elements have high polarizing power due to their small atomic and ionic sizes, which leads to a high charge density on the nucleus. This high charge density results in a stronger attraction to the electrons in neighboring atoms, causing distortion in their electron cloud. This ability to distort the electron cloud of neighboring atoms is what gives transition elements high polarizing power.
Why does the amount of water affect time it takes to boil?
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
Why Pbcl2 is ionic and Pbcl4 is covalent?
apply fazan's rule, greater the charge on cation more is the polarising power and hence more covalent character polarising power of pb4+>pb2+ thus pbcl4 is more covalent than pbcl2 conversely pbcl2 more ionic than pbcl4

What is an express boil point in Watts?
Boiling points are expressed in units of temperature, such as degrees Celsius or Kelvin - not in units of power.
What do carbonates become more stable to thermal decomposition as they go down group 2?
The size of the group 2 ions gets bigger as we go down the group. Hence, their polarising power also decreases. So, the carbonates are less polarised as we go down the group, requiring more energy to decompose them. Polarising power is the ability of the ion to attract the bonding pair of electrons towards itself.
How is steam produced?
Steam is produced by boiling water to its vapor phase. This is typically done in a boiler by applying heat to the water, resulting in the water reaching its boiling point and turning into steam. The generated steam can then be used in various applications such as power generation, heating, or industrial processes.
What are the applications of water's boiling point?
Water's boiling point is used in various applications, such as in cooking to steam and boil foods, in distillation processes to separate liquids based on their boiling points, in power plants to generate steam for turbines, and in laboratory settings for heating solvents and reactions.

Why lif is not polar?
The electronegativity difference of 3.0 indicates an ionic bond rather than a polar covalent. However LiF is not very soluble, like other Li salts. This is due to a partial covalent character in the bond due to the high polarising power of the small Li+ ion which distorts the electron cloud round the anion. The extent of this effect caused by cations is predicted in "Fajan's Rules"
What is the file type for a Power Point File?
