The answer is 0.10 M NaOH. The NaCl is neutral. The HCl is acid. NaOH and NaNO2 are base. The base has higher pH than acid. The NaNO2 is weak base while NaOH is strong base. So the NaOH has higher pH than NaNO2.

The proper name for a carbohydrate polymer with 2 subunits is
valentina_108 [34]
Carbohydrates are classified in three major categories depending upon the number of sub units joining to form them. These are,

                                                Monosaccharides

                                                Oligosaccharides

                                                Polysachharides

The simplest single units are monosaccharides, if units are ranging between two and twenty they are called oligosaccharides and above twenty joining units they are called polysachharides.

Result:
          <span>The proper name for a carbohydrate polymer with 2 subunits is called Oligosachharide in general and Disaccharide in specific.</span>

Indicate the mechanistic symbol (SN1, SN2) that is most consistent with the following statement. Select the single best answer.
Degger [83]

Answer:

The most consistent mechanism is SN1.

Explanation:

The solvolysis of tert-butyl iodide in methanol will arise by the SN1  mechanism.

The reason for that is due the geometric structure of tert-butyl. The tertiary structure allows the formation of a stable carbocation, after the loss of the iodide ion. The carbocation will then be attacked by methanol molecules forming an eter.

Explain why it was important for scientists to have a standard system of naming compounds and other chemical procedures.
Minchanka [31]

It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.

Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.

Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.
