Which of the following is a property of bases?
B. Feels slippery
This is most likely the Chemical Properties of Bases
The Chemical Properties of Bases include:
- Bases change the colour of litmus from red to blue.
- They are bitter in taste.
- Bases lose their basicity when mixed with acids.
- Bases react with acids to form salt and water. This process is called Neutralisation Reaction(Read).
- They can conduct electricity.
- Bases feel slippery or soapy.
- Some bases are great conductors of electricity.
- Bases like sodium hydroxide, potassium hydroxide, etc are used as electrolytes.
- Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.
- Strong alkalis are highly corrosive in nature whereas other alkalis are mildly corrosive.
- The pH value of bases ranges from 8-14.
Alkalis and ammonium salts produce ammonia.
- Hydrogen gas is evolved when metals react with a base.
- Bases are classified on the basis of strength, concentration and acidity.
- The different kinds of acids are strong base acid, weak base acid, concentrated base, dilute base, monoacidic base, diacidic base and triacidic base.
The heat released from the calculation is 33.56 kJ.
<h3>Heat of vaporization</h3>
The heat of vaporization is the heat absorbed when a substance changes from liquid to vapor. It is equal to the heat released when the vapor is condensed.
The total heat released = Heat of condensation + Heat lost to the skin
= (13.3 g × 2260 J/g) + (13.3 g × 4.18 J/g/°C × ( 100 - 37)°C)
= 30058 + 3502
= 33.56 kJ
The heat released from the calculation is 33.56 kJ.

Type of intermolecular forces are expected between 3-bromopyridine molecules dipole induced dipole force.
Intermolecular pressure is the pressure among molecules it includes the forces of appeal and repulsion. however the intermolecular forces are weaker than intramolecular pressure, has London dispersion pressure.
Dipole precipitated Dipole Forces A dipole-brought on dipole enchantment is a weak enchantment that results while a polar molecule induces a dipole in an atom or in a non polar molecule by traumatic the arrangement of electrons inside the non polar species.
It is a dipole as the hydrogens have a partial superb fee and the oxygen has a partial negative charge. An precipitated dipole is the end result of molecules interacting and causing one of the molecules electrons to have this distorted rate.
