Answer:

The IUPAC name of the compound is 3-ethyl, 4-methyl, heptane.

Explanation:

IUPAC stands for International Union of Pure and Applied Chemistry.

An IUPAC name is a internationally used name of a compound with same name throughout the world. This compound is named according to the IUPAC rules with the following steps-

1. Identification of longest carbon chain.

2. Estimating the number of carbon in the longest carbon chain that is seven carbon means heptane.

3. The side chains are identified, that are branched off from the parent chain.

4.  The parent chains is labelled from the side of nearest side chain.

5. The nearest side chain that is the third carbon contains ethyl as the side chain at 3 position of parent carbon. Thus, so named 3-ethyl.

6. The fourth carbon of parent chain contain a methyl group, thus named as 4-methyl.

The naming is based on the parent carbon chain and side chain naming are written first. Thus, the compound is 3-ethyl, 4-methyl, heptane.

Answer:

3-ethyl-4-methyl Heptane

Explanation:

longest chain is straight .

we start assigning number from where we are close to the branch to this mean its from left hand side. and we saw two chain 1 is ethyl and other is methyl . In alphabetical order e comes first as compare to m so we write ethyl first after that methyl and than in last we write longest chain name with ane (bcz we only have single vonds).

Why is concentrated sodium hydroxide preferred than water
mariarad [96]

Answer:

Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH

2O.[11] The monohydrate NaOH·H

2O crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound.

As one of the simplest hydroxides, sodium hydroxide is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students.[12]

Sodium hydroxide is used in many industries: in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner. Worldwide production in 2004 was approximately 60 million tons, while demand was 51 million tons.[13]

117 mL of 0.210 M K₂S solution

Explanation:

The question asks about the volume of 0.210 M K₂S (potassium sulfide) solution required to completely react with 175 mL of 0.140 M Co(NO₃)₂ (cobalt(II) nitrate).

We have the chemical reaction:

K₂S + Co(NO₃)₂ → CoS + 2 KNO₃

molar concentration = number of moles / volume (L)

number of moles = molar concentration × volume

number of moles of Co(NO₃)₂ = 0.140 × 175 = 24.5 mmoles

We see from the chemical reaction that 1 mmole of Co(NO₃)₂ is reacting with 1 mmole of K₂S, so 24.5 mmoles of Co(NO₃)₂ are reacting with 24.5 mmoles of K₂S.

volume = number of moles / molar concentration

volume of K₂S solution = 24.5 / 0.210 = 117 mL
