In the covalent bond between hydrogen and chlorine in the HCl molecule, where will the majority of shared electrons be found?

2 answers:

7 0

In covalent bonds, majority of shared electron is towards element with more electronegativty. Since Cl is more electronegative than H, shared electrons will be towards Cl.

Nearer to the chlorine as it has a greater electronegativity

In a titration of monoprotic acids and bases, there is a large change in pHA. at the point where pH = pKa of the acid.B. when th

Jobisdone [24]

Answer:

D. when the number of moles of acid is exactly equal to the number of moles of base.

Explanation:

Regarding options A. and E., pKa and pKb would only be taken into consideration if the titrations were of weak acids and bases. However it is possible to have a titration of monoprotic acids and bases with strong acids and bases.

Another way of looking at the answer is identifying which one best describes the equivalence point.

Ascorbic acid, of vitamin c (c6h8o6), is an essential vitamin. it cannot be stored by the body and must be present in the diet.

Inessa [10]

Molecular formula of ascorbic acid is $C_{6}H_{8}O_{6}$

Molar mass of ascorbic acid = $(6 * 12 g/mol) + (8 * 1 g/mol) + (6 * 16 g/mol) = 176 g/mol$

Converting 500.0 mg of ascorbic acid to moles: We use molar mass of ascorbic acid to convert mass to moles.

$500.0 mg * \frac{1 g}{1000 g} *\frac{1 mol}{176 g} = 0.00284 mol$

Converting 500.0 mg of ascorbic acid to molecules: The conversion factor used is 1 mole = $6.022*10^{23} molecules$

$500.0 mg * \frac{1 g}{1000 mg}*\frac{1 mol}{176 g} * \frac{6.022*10^{23}molecules}{1 mol} = 1.71 * 10^{21} molecules$

What is the pH of a solution that has [H+] of .0042M?

sveticcg [70]

Answer:

pH = 2.4

Explanation:

pH is defined as the negative log of the hydronium concentration.

Thus, we can plug in the given hydronium concentration:

pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)

The pH of the solution is 2.4.

P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.
