Answer:

3,4–diethyloctane

Explanation:

To name the compound, we must do the following:

1. Locate the longest continuous carbon chain. This gives the parent name of the compound. In this case, the longest chain is carbon 8 i.e octane.

2. Identify the substituent attached to the compound. In this case, the substituent group attached is ethyl i.e CH2CH3.

Note: there are two ethyl group attached to the compound.

3. Locate the position of the substituent group attached, giving them the lowest possible count. In this, the ethyl group are at carbon 3 and 4.

4. Combine the above to get the name of the compound. Therefore, the name of the compound is:

3,4–diethyloctane.

Rank these systems in order of decreasing entropy. 1 = Greatest entropy and 7 = Least entropy. Group of answer choices 1 mol of

AlladinOne [14]

Answer:

1 mole of carbon disulfide gas at 273 K and 40 L
1 mol of chlorine gas at 273 K and 40 L
1 mol of neon gas at 273 K and 40 L
1 mol of neon gas at 273 K and 20 L
1/2 mol of neon gas at 273 K and 20 L
1/2 mol of neon gas at 100 K and 20 L
1/2 mol of liquid neon at 100 K

Explanation:

Entropy is the measure of disorder or randomness in a closed system. Its an extensive property of a thermodynamic system

The following points must be considered when ranking the systems according to their entropy:

The entropy of gases are highest than liquids or solid. And entropy of liquid is higher than solid. That is because gas has more microstate thus have the highest entropy.
Entropies of large complicated molecules are greater than those of smaller, simpler molecules. Because larger molecules have more disorder because of the greater number of ways they can be move around in three dimensional space.
highest temperature and highest volume will lead to greatest entropy
1 mole of any substance will have greater entropy than 1/2 mole of that same substance

Select the net ionic equation for the reaction that occurs when sodium carbonate and nickel(II)

Gwar [14]

Answer:

Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)

Explanation:

First let us put down the molecular equation of the reaction

Na2CO3(aq) + Ni(NO3)2(aq)----> 2NaNO3(aq) +NiCO3(s)

Hence ionically, we will have the reaction as;

Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)

The ionic equation usually indicate the ions that actually take part in the reaction. They often lead to the formation of the solid product or precipitate.

The order ions that are no shown in the ionic reaction equation are called spectator ions.

Hence, the reaction shown in the answer is the ionic reaction equation for the mixing of nickel II nitrate and sodium carbonate.
