Draw the conjugate acid of ethanol

Chemistry
1 answer:
Snezhnost [94]3 years ago
5 0

Answer:

H₃O⁺.

Explanation:

Hello,

In this case, ionization of ethanol yields hydrogen cations and ethoxide anions as follows:

CH_3COOH+H_2O\rightleftharpoons H_3O^++CH_3COO^-

Which is at equilibrium as ethanol is a weak acid. Thus, since the conjugate acid is formed by the outgoing H⁺ and the water, we say that the conjugate acid is then the hydroxonium ion, H₃O⁺ whereas the conjugate base is the remaining anion CH₃COO⁻.

Best regards.

Where can you find the number of electrons of an<br> element?
andrezito [222]

Answer:

Subtract the charge from the atomic number. When an ion has a positive charge, the atom has lost electrons. To calculate the remaining number of electrons, you subtract the amount of extra charge from the atomic number. In the case of a positive ion, there are more protons than electrons.

Which physical change is endothermic?
Helen [10]

Answer: The correct option is 1.

Explanation: Endothermic reactions are the reactions in which heat is provided to break down the reactant molecules.

In option 1:

The stronger intermolecular forces between the particles in solid molecule are broken down to convert into gaseous form. Hence, some energy in the form of heat is provided to move them far apart. Therefore, it is considered as an endothermic reaction.

In option 2, 3 and 4:

All the other processes involves the formation of bonds and thus there is no need to provide any energy.

Which statement best explains why calcium has a larger atomic radius than magnesium? A. Calcium has a stronger nuclear charge th
ahrayia [7]

Answer:

B. calcium has electrons in more energy levels than magnesium

Explanation:

atoms are made of three types of subatomic particles - electrons, protons and neutrons.

Neutrons and protons reside in the nucleus of the atom and electrons reside in energy shells

electronic configuration for both Ca and Mg are as follows

Mg - 2,8,2

Ca - 2,8,8,2

outermost energy shell of Mg with electrons is the third energy level

whereas outermost energy shell of Ca with electrons is the fourth energy shell

therefore Ca has a larger atomic radius than Mg as it has one more energy shell than Mg in which electrons reside

A 0.105 L sample of an unknown HNO 3 solution required 35.7 mL of 0.250 M Ba ( OH ) 2 for complete neutralization. What is the c
oksano4ka [1.4K]

Answer: 0.17M

Explanation:

The equation for the reaction is :

2HNO3 + Ba(OH)2 —> Ba(NO3)2 + 2H2O

From the balanced equation, we obtain :

nA = mole of acid = 2

nB = mole of the base = 1

From the question, we obtain:

Va = Vol. Of acid = 0.105L

Ma = conc. Of acid =?

Vb = Vol of base = 35.7 mL = 0.0357L

Mb = conc. of base = 0.25M.

We solve for the conc. of the acid using:

MaVa / Mb Vb = nA / nB

(Ma x 0.105) / (0.25x0.0357) = 2

Cross multiply to express in linear form. We have:

Ma x 0.105 = 0.25 x 0.0357 x 2

Divide both side by 0.105. We have

Ma = (0.25 x 0.0357 x 2) / 0.105

Ma = 0.17M

Therefore the concentration of the acid(HNO3) is 0.17M
