Which activity removes a large amount of alcohol from the body? After alcohol has been consumed and reaches the bloodstream, up to 10% of the alcohol is disposed of through the urine, and 80% to 90% by oxidation in the liver. The average drinker eliminates about 2/3 of a standard drink unit (a shot) per hour.

Which member of each pair is the stronger base? part a ethylamine or aniline ethylamine or aniline ethylamine aniline request an

Vladimir79 [104]

Lowery-Bronsted theory is applied here. Acc. to this theory Base accepts protons and Acids donate proton.

Part 1:
Aniline is less basic than ethylamine because the lone pair on nitrogen (which accepts proton) is not localized. It resonates throughout the conjugated system of phenyl ring. Hence due to unavailability of electrons for accepting proton it is less basic compare to ethylamine. In ethyl amine the lone pair of electron is localized and available to abstract proton.

Part 2:
In this case the alkyl groups attached to -NH₂ (in ethylamine) and -O⁻ (in ethoxide are same (i.e. CH₃-CH₂-). Ethoxide is more basic than ethylamine because ethoxide is a conjugate base of ethanol (pKa value of ethanol = 15.9 very weak acid) and the conjugate base of weak acid is always a strong base. Secondly, the oxygen atom more Electronegative than Nitrogen atom can attract more electron cloud from alkyl group as compared to Nitrogen in ethylamine. Hence, oxygen in ethoxide attains greater electron cloud than the nitrogen in ethylamine. Therefore, it is more basic than ethylamine.

-The picture goes to Activity 2

Alborosie

Answer:

Activity 1: Since the only forces apposing the upward movement of the load are gravity and air resistance the formulas of which can both be solved with weight then with constant variables for gravity and air, effort IS directly proportional to weight.

Inclined plane.

to make lifting easier; raising or lowering a load.

If 20.0g of CO2 and 4.4g of CO2

Ksivusya [100]

The given question is incorrect. The correct question is as follows.

If 20.0 g of $O_{2}$ and 4.4 g of $CO_{2}$ are placed in a 5.00 L container at $21^{o}C$ , what is the pressure of this mixture of gases?

Explanation:

As we know that number of moles equal to the mass of substance divided by its molar mass.

Mathematically, No. of moles = $\frac{\text{mass}}{\text{molar mass}}$

Hence, we will calculate the moles of oxygen as follows.

No. of moles = $\frac{\text{mass}}{\text{molar mass}}$

Moles of $O_{2}$ = $\frac{20.0 g}{32 g/mol}$

= 0.625 moles

Now, moles of $CO_{2} = \frac{4.4 g}{44 g/mol}$

= 0.1 moles

Therefore, total number of moles present are as follows.

Total moles = moles of $O_{2}$ + moles of $CO_{2}$

= 0.625 + 0.1

= 0.725 moles

And, total temperature will be:

T = (21 + 273) K = 294 K

According to ideal gas equation,

PV = nRT

Now, putting the given values into the above formula as follows.

P = $\frac{nRT}{V}$

= $\frac{0.725 mol \times 0.08206 Latm/mol K \times 294 K}{5.00 L}$

= $\frac{17.491089}{5}$ atm

= 3.498 atm

or, = 3.50 atm (approx)

Therefore, we can conclude that the pressure of this mixture of gases is 3.50 atm.

Choose the term that best fits the following definition: the liquid or gas that carries the sample across the solid support.

iren [92.7K]

The correct answer is option B.

The liquid or gas that carries the sample across the solid support is called mobile phase.

In chromatography, there are two phases: mobile phase and solid phase.

The mobile phase can be either in gas form or liquid form.

While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.

In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.

on the other hand, stationary phase is motionless.
