Answer:
Acetic acid is a weak acid because it partially dissociates into its constituent ions when dissolved in water. This weak acid is known to form miscible mixtures with water. An acetic acid is an acid that ionizes only slightly in an aqueous solution. Therefore it's a weak acid.

The answer is <span>Na: positive; Cl: negative.
NaCl is a binary ionic compound, meaning its a compound that has an anion, which is a positive ion and a cation, which is negative ion. On the periodic table, Na is in row 1A, which all have a positive charge because there is 1 more proton than electrons and Cl is in row 7A, which all have negative charges because there is 1 more electron than protons.

Answer:
It increases in value positively
Explanation:
The entropy of a chemical reaction can be defined as the degree of disorderliness. Hence when we talk about entropy, we are talking about the degree of randomness associated with that specific chemical reaction. The burning of wood is a kind of spontaneous reaction.
For a reaction to be spontaneous, the change in free Gibbs energy must be negative. To make this a reality, at constant enthalpy, the reaction temperature and change in entropy is expected to be negative in value. To get this negative value needed, it is essential know that the value of the entropy must increase as the temperature of the burning wood is increasing too.
