The structure of sodium benzoate and benzoic acid is shown in the image.
Sodium benzoate is a sodium salt of benzoic acid.
Benzoic acid is an organic compound and weak acid means it does not dissociates in water that means it is sparingly soluble in water. Whereas the sodium benzoate is an ionic compound and dissociates completely in water to give sodium ions and benzoate ions that means it is highly soluble in water.
Thus, through solubility of benzoic acid and sodium benzote in water we can show difference between benzoic acid and sodium benzote. As, benzoic acid is sparingly soluble and sodium benzoate is highly soluble in water.
Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!
Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!
The answer is light years
HNO₃(aq) +Ca(OH)₂(aq) --> H₂O(l) + Ca(NO₃)₂(aq)
It is Ca(NO₃)₂ because NO₃ has a charge of -1, and Ca has a charge of 2+. And when writing an ionic compound, you take the charge of 1 and write it as the subscript of the other.
Now let's balance the equation and then find the net ionic equation.
2HNO₃(aq) +Ca(OH)₂(aq) --> 2H₂O(l) + Ca(NO₃)₂(aq)
2H⁺(aq) + 2NO₃⁻(aq) + Ca²⁺(aq) + 2OH⁻(aq) --> 2H₂O(l) + Ca²⁺(aq) + 2NO₃⁻(aq)
We can get rid of the spectator ions. These are the ions that are on both sides.
We are left with
2H⁺(aq) + 2OH⁻(aq) --> 2H₂O(l)
We can simplify the net ionic equation down to
H⁺(aq) + OH⁻(aq) --> H₂O(l)
