Which type of bond exemplifies a weak chemical bond? covalent bonds in solution hydrogen bonds in solution ionic bonds in solids

vova2212 [387]

Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.

What is a chemical bond?

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.

Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring

ludmilkaskok [199]

Answer:

1.20 V

Explanation:

$Pb(s) + Br_2(l)\rightarrow Pb^{2+}(aq) + 2Br^-(aq)$

Here Pb undergoes oxidation by loss of electrons, thus act as anode. Bromine undergoes reduction by gain of electrons and thus act as cathode.

$E^0=E^0_{cathode}- E^0_{anode}$

Where both $E^0$ are standard reduction potentials.

Given,

$Pb^{2+}(aq) + 2 e^-\rightarrow Pb(s)$

$E^0_{[Pb^{2+}/Pb]}= -0.13\ V$

$Br_2(l) + 2 e^-\rightarrow 2 Br(aq)$

$E^0_{[Br_2/Br^{-}]}=+1.07\ V$

$E^0=E^0_{[Br_2/Br^{-}]}- E^0_{[Pb^{2+}/Pb]}$

$E^0=+1.07- (-0.13)\ V=1.20\ V$

gA scientist is trying to discover information about an unknown metal in a compound. The formula for the compound is believed to

Hitman42 [59]

Solution :

It is given that :

The formula of the compound = $XBr_3$

And that 4.70 g of the sample contains $4.834 \times 10^{-2}$ mol of Br.

It means that :

1 mol of $XBr_3$ contains = 3 mol of Br

∴ 3 mol of $Br^-$ contain in 1 mol of $XBr_3$

$4.834 \times 10^{-2}$ mol of $Br^-$ contains $1.576 \times 10^{-2}$ mol of $XBr_3$

Thus the mol of $XBr_3$ = $1.576 \times 10^{-2}$ mol

The given mass is = 4.700 g

Therefore, the $\text{molar mass}$ of $XBr_3$ $=\frac{\text{mass}}{\text{mol}}$

$=\frac{4.700 \ g}{1.576 \times 10^{-2} \ mol}$

= 298.4 g/mol

So $\text{molar mass}$ of $XBr_3$ = $\text{molar mass}$ of X + 3 x $\text{molar mass}$ of Br

298.4 g/mol = $\text{molar mass}$ of X + 3 x 79.90 g/mol

298.4 g/mol = $\text{molar mass}$ of X + 239.7 g/mol

$\text{molar mass}$ of X = 58.71 g/mol (since 1 amu = 1 g/mol)

Therefore the atomic mass of the unknown metal = 58.71 g/mol

So the unknown meta is Nickel.

What precautions should be observed when an aqueous sodium carbonate solution is used to extract an organic solution containing

Vladimir [108]

The biggest precaution that should be followed is to not wall the separatory funnel off too tightly. When the sodium carbonate solution is used, the acid will react with it to create carbon dioxide. This can build up in the funnel, leading to an increase in pressure that could cause a rupture if enough is created.
