Why does iron wool react with HCl faster then an iron nail or the same mass?
Because the surface area of iron wool is higher, the area exposed to acid is higher.
Is 1 m HCl is more reactive than 4m HCl?
1 m HCl is not more reactive than 4m HCl, but 4m HCl is more concentrated.
Why does hydrogen chloride have a low melting point?
HCL has a low m.p because of the covalent bond which is weaker as compared to ionic bonds. So low amount of heat is needed in order to break these bonds and hence the mp is low
What would have occurred if the magnesium were to slide to the HCl in the boiling tube before the system was sealed off?
The hydrogen gas (H2) formed would escape and not be detected.
Halite reaction to HCl?
Halite does not react with HCl.
Which has the higher boiling point NaCl or HCl and why?
Sodium chloride has a higher boiling point because is a salt with ionic bonds.
Which has a higher boiling point HI or HCl?
HI has a higher boiling point because of the dipole-dipole Intermolecular forces as well as the dispersion forces, which become more evident with molecular weight, which will dominate over the dipole-dipole forces, so HCl has a lower boiloing point.
HF HCl boiling temperature?
Boiling point of HCl: -85,1 0C. Boiling point of HF: 19,5 0C.
Why has HF higher boiling point than HCl?
becaus H-F forming hydrogen bond will the H-Cl dos'n
Which molecule has a higher boiling point Cl2 or Br2?
HCL has a higher boiling point compared to HBr This is due to difference in electronegativity. H - 2.1 Cl - 3.0 Br - 2.8 The difference for HCl is 0.9, the difference for HBr is 0.7. The larger the difference in electronegavity means the stronger the bond. Large difference means greater attraction hence more energy is needed to overcome this bond.
What is the boiling point of hydrochloric acid or HCl?
The boiling point of hydrochloric acid will depend on its concentration (when mixed with water). For a solution of about 20%, it's 110 °C (230 °F, 383 K). Higher concentrations boil at lower temperatures. Remember that the fumes and/or vapors of HCl are very dangerous! A link is provided to the Wikipedia article on this dangerous acid. The boiling point of hydrogen chloride (HCl) is -85,1 0C.
Why is the boiling point of HI higher than HBr?
This is to do with the intermolecular forces in the two compounds. There are no hydrogen bonds between the molecules of either compound, since Br and I are not electronegative enough to polarise the molecules sufficiently. But since HI molecules contain more electrons than HBr, there are increased van der Waals forces in HI. For the same reason HBr has a higher boiling point than HCl, but HF has a higher boiling point than HCl, HBr or HI because of hydrogen bonding.
Which has a higher melting point HF NaCl HCl Cl2?
NaCl has ther highest melting point, as it is a solid at room temeprature. The other are gases and there fore have much lower boiling points and lower again for melting points.
Why is the boiling point of methane much lower than the boiling point of hydrochloric acid?
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
Highest boiling point between NH3 HCl H2 and KI?
The highest boiling point beween these compounds: potassium iodide (KI) with 1 330 0C.
What is the boiling point of liquid Hydrogen Chloride gas?
Only a liquid can boil. HCl boils at -84.9C
Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?
