Make a claim for why caco3 reacts more vigorously with hcl than with hc2h3o2

Chemistry

Maru [420]1 year ago
3 0

CaCO₃ reacts more vigorously with HCl than with CH₃COOH because HCl is a strong acid and acetic acid is a weak acid.

<h3>What is calcium carbonate?</h3>

Calcium carbonate (CaCO₃) is a salt of strong base and weak acid so that it can react with any acid.

Among hydrochloric acid (HCl) and acetic acid (CH₃COOH), HCl is a strong acid means it completely dissociates into their respective ions and acetic acid is a weak acid. So due to strong basic nature of calcium carbonate it vigorously reacts with strong HCl acid.

Hence due to strong acidity of HCl, CaCO₃ vigorously react with HCl.

adell [148]

Answer:

The correct answer is vertebrate enzyme hydrolyze alpha-1,4 glycosidic linkage but not glucose in the beta configuration.

Explanation:

The amylase that is present inside human body is called salivary alpha amylase,an enzyme that digest the alpha-1,4-glycosidic linkages of starch but does not act on those glycosidic linkages which are present in beta configuration.

       Cellulose contain beta-1,4-glycosidic linkages.That"s why it is not digested by the alpha amylase enzyme present inside the human body basically present in the saliva.

Which of the following best helps to explain why the electron affinity of Br has a greater magnitude than that of I?
tankabanditka [31]

The reason why  Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.

In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.

Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.

Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than  I.

A 1.0l buffer solution contains 0.100 mol of hc2h3o2 and 0.100 mol of nac2h3o2. the value of ka for hc2h3o2 is 1.8×10−5. part a
Mandarinka [93]
There are two ways to solve this problem. We can use the ICE method which is tedious and lengthy or use the Henderson–Hasselbalch equation. This equation relates pH and the concentration of the ions in the solution. It is expressed as

pH = pKa + log [A]/[HA] 

 where pKa = - log [Ka]
[A] is the concentration of the conjugate base
[HA] is the concentration of the acid

Given:
Ka = 1.8x10^-5
NaOH added = 0.015 mol
HC2H3O2 = 0.1 mol
NaC2H3O2 = 0.1 mol

Solution:
pKa = - log ( 1.8x10^-5) = 4.74

[A] = 0.015 mol + 0.100 mol = .115 moles
[HA] = .1 - 0.015 = 0.085 moles

pH = 4.74 + log (.115/0.085)
pH = 4.87
