stearic acid and linoleic acid stearic acid and linoleic acid stearic acid has the higher melting point, because it has two more

Acid palmitic acid has higher melting point, because it has two more methylene groups.

\text { Myristic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{12} \mathrm{COOH} \\& \text { Palmitic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{14} \mathrm{COOH} \\

Acid palmitic acid has higher melting point, because it has two more methylene groups.

Giving it a greater surface area and therefore more intermolecular  van der waals interact than the myristic acid.

stearic arid \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{16} \mathrm{COOH}

linoleic acid \mathrm{C}_{18} \mathrm{H}_{32} \mathrm{O}_2 (two double bond)

Stearic acid has higher Melting point, because it does not have any Carbon-Carbon double bonds, whereas linoleic acid has two cis double bonds which prevent the molecules from packing closely together.

Oleic Acid and Linoleic acid.

\mathrm{C}_{18} \mathrm{H}_{34} \mathrm{O}_2-one double bond (cis)

Acid palmitic acid has higher melting point, because it has two more methylene groups.

pantera1 [17]

Answer:

1. HgO(s) → Hg(l) + 0.5 O₂(g)

2. 0.858 g

Explanation:

There is some info missing. I think this is the original question.

<em>The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. </em>

<em>1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. </em>

<em>2. Suppose 59.0 mL of dioxygen gas are produced by this reaction, at a temperature of 90.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.</em>

<em />

1.

The balanced chemical equation is:

HgO(s) → Hg(l) + 0.5 O₂(g)

2.

First, we will calculate the moles of O₂ using the ideal gas equation.

P × V = n × R × T

n = P × V / R × T

n = 1 atm × 0.0590 L / 0.0821 atm.L/mol.K × 363.2 K

n = 1.98 × 10⁻³ mol

The molar ratio of HgO to O₂ is 1:0.5. The moles of HgO are (1/0.5) × 1.98 × 10⁻³ mol = 3.96 × 10⁻³ mol

The molar mass of HgO is 216.59 g/mol. The mass of HgO is:

3.96 × 10⁻³ mol × 216.59 g/mol = 0.858 g

Select the single best answer. Determine the following type of reaction: CH3―CH2―CH(Br)―CH3 CH3―CH═CH―CH3 + NaBr + H2O
Setler79 [48]

Answer:

Deshydrohalogenation

Explanation:

You are not providing options to answer, however, this can be answered without options.

Now, in the reaction we can see that we have an atom of Bromine in carbon 2, and in the product appears as NaBr. This means that the Br was substracted by elimination. It's an elimination because the final product do not have a substituent where the bromine was, (Like another nucleophyle such OH or another halide). If you look closely the final product, we can see that one hydrogen in carbon 3, is no longer there. So this electrophyle was also substracted, in this case, by a base (Such NaOH), so in this case, it's ocurring an elimination reaction via E2 (One step, bimolecular). So, as the final product has been substracted the nucleophyle and electrophyle, this treaction is a deshydrohalogenation (an atom of hydrogen and a halide were substracted). The mechanism of this, you can see it in the picture.

How would Lithium gain full valence levels
Lubov Fominskaja [6]

Answer:

In order to have a full outer shell atoms can GAIN or LOSE electrons. Atoms with very few VALENCE electrons, such as Lithium, would need to gain many electrons for a full shell so it is easier for them to LOSE electrons and become POSITIVE.

Explanation:

- I hope this helped!
