When exactly half of the ch3co2h has been converted to ch3co2-, what is the ratio:.

Answers

Answer 1

The ratio of converting CH3CO2 is 49:1.

Calculation:-

The pH of an acidic buffer is calculated by Henderson equation as:

pH = pKa + log [ salt]  / [acid]

Given, ka for acetic acid = 1.76 x 10^-5

Therefore, pKa = -log ka = - log 1.76 x 10^-5

= 5 - log 1.76 = 5 - 0.246 = 4.75

pH = 4.44

Hence, using Henderson's equation,

pH = pka + log [CH3COO- ] /[CH3COOH]

4.44 = 4.75 + log [CH3COO- / CH3COOH]

log [CH3COO- / CH3COOH ] = -  0.31

[CH3COO- / CH3COOH] = antilog -0.31 = 0.49

Therefore, ratio of ,  [CH3COO- / CH3COOH]  = 0.49 : 1

Ratios indicate how often one number contains another number. The term ratio is used in social media sensation and refers to situations where a post has a higher percentage of replies compared to likes and reposts.

how many sigma and pi bonds are in this molecule (aka benzene)? enter a number, e.g. 0, 1, 2... what is the hybridization on the carbons? for hybridization enter either sp, sp2, sp3, sp3d, sp3d2

Answers

Hybridization determines what kind of connection is formed around the core atom. All four bonds involved in hybridization are sigma bonds. As a result, the hybridised atom has no pi bonds.

In benzene, where may one find pi bonds?

Each of the six carbon atoms in benzene's cyclic arrangement of six carbons has a hydrogen atom attached to it. In benzene, there are 3 pi bonds that alternate with 6 sigma bonds connecting the carbon atoms. Four electrons in bonded electron pairs make up each carbon atom. Three of these are involved in sigma bonding, while one helps form a pi bond.

The pressure exerted by a vapour in thermodynamic equilibrium with its condensed phases (solid or liquid) at a specific temperature in a closed system is referred to as vapour pressure (or vapour pressure in English-speaking nations other than the US; see spelling variants). A liquid's evaporation rate can be determined by looking at the equilibrium vapour pressure. It has to do with how often particles tend to float away from liquids (or a solid). Volatile is a term used to describe a chemical that has a high vapour pressure at room temperature. Vapor pressure is the force that vapour exerts when it is present above a liquid surface.

A nucleophile is a chemical entity in chemistry that establishes bonds by giving up a pair of electrons. Nucleophiles include all ions and molecules with a free pair of electrons or at least one pi bond. Lewis bases are nucleophiles because they donate electrons.

How does a nucleophile develop?

As a nucleophile, the hydroxide ion contributes two electrons to an electrophilic atom, in this case the carbon atom, to create a new covalent bond.

Answers

The molar solubility of salt is 6.542 x 10⁻⁵ mol/L

What is molar solubility?

It is the number of moles of solute in a saturated solution that is one litre in size. It is expressed in moles per litre.A compound's capacity to dissolve in a given substance is known as its molar solubility (M), which is a unit of measurement. Molar solubility is measured as moles/L and is more specifically the maximum number of moles of a solute that can dissolve in one litre of solvent. The solution is said to be saturated when the amount of solute it can dissolve in one litre of solvent equals the amount of moles dissolved in one mole of solvent.

There are several factors that affect M's value. The Ksp value of the solubility product constant is significant. Each compound's measure of how readily a substance dissolves has a fixed value. Calculating the value of M also requires knowledge of the chemical reaction's product-to-reactant ratio. The reaction's stoichiometry is what is meant by this

Co(OH)₂ dissociates in solution according to the equation:

Ag₂CrO₄ → 2Ag⁺ + CrO₄²⁻.

∵ Ksp = [Ag⁺]²[CrO₄²⁻] = (2s)²(s) = 4s³.

∴ 4s³ = 1.12 x 10⁻¹².

∴ s³ = 1.12 x 10⁻¹²/4 = 2.80 x 10⁻¹³.

∴ s = ∛(2.80 x 10⁻¹³) = 6.542 x 10⁻⁵ mol/L

Under the presumption of an ideal gas, this empirical relation can be deduced from the kinetic theory of gases.

how many grams of chlorine gas are produced in the following reaction from 0.490 g hydrogen and 50.0 g chlorine? which substance is the limiting reactant?

Answers

The HCl concentration formed is 17.6 g and the limiting reactant is hydrogen.

In this case, based on the information provided, the grams of HCl required can be calculated by first identifying the limiting reactants in moles of each reactant.

1:1 mole ratio

nH₂ = 0.490 g H₂ x 1 mol H₂ / 2.02 g H₂ = 0.242 mol H₂

nCl₂ = 50.0 gCl₂ x 1 mol Cl₂ / 70.9 g Cl₂ = 0.705 mol Cl₂

From this we conclude that hydrogen is the limiting reactant and use 1:2 molar ratio with HCl having a molar mass of 36.46 g/mol:

mHCl = 0.242 mol H2; x 2 mol HCI/1 mol H2. x 36.6 g HCl/1 mole HCl

mHCl = 17.6 g HCl

Therefore, the HCl concentration formed is 17.6 g and the limiting reactant is hydrogen.

Energy explanation

Geothermal electricity generation is done by drilling the ground in areas that have geothermal potential to create hot gas holes which will be used to heat the boiler so that the steam can drive a steam turbine connected to a generator. For geothermal energy that has high pressure, it can directly rotate the generator turbine, after the steam that comes out is cleaned first.
