See explanation.
Explanation:
Hello!
In this case, since we are asked to note down the complete molecular equation, complete ionic equation and the net ionic equation for the reaction between acetic acid (weak acid) and barium hydroxide (strong base), we proceed as shown below:
- Complete molecular equation:
- Complete ionic equation: in this case, since acetic acid is a weak one, it is not ionized, so we do this:
- Net ionic equation: in this case, we cancel out the barium ions as they are the spectators one because they are present at both reactants and products:
Best regards!
Answer:
A strip of magnesium metal is ignited using a lighter wand. The result is
an intensely glowing white light. As the burning of the metal subsides, a
white powder-like substance now appears replacing the smooth ribbon of
metal.
It can change in C. compounds to change when elements combine that will form
Answer:
O2 - exhibits dispersion forces as its strongest intermolecular force.
Explanation:
Generally speaking, all biatomic homonuclear molecules, such as N2, O2, F2, do NOT have any dipole moment: the distibution of the nuclear clouds is symmetrical. They are non-polar.
For what concerns heteronuclear molecules, it depends on their geometry.
Dispersion force ( Van der Waal)< dipole dipole < hydrogen bond
Intermolecular forces are forces of attraction between molecules/atoms based mainly on the idea of like charges repel and opposite charges attract.
Based on the polarity of the substance, the type of intermolecular forces existing between substance may be different.
