A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture, or material type.

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

Pressure drop in packed column ..... a tray column

Stolb23 [73]

Answer:

The answer is b)

Explanation:

In packed column the mass transfer area is higher and the packing can be random, that could provoque an increase in the pressure, because obstruction of the mass flux, While in a tray column the sieves can have specific porosity and the flux of mass can be facilitated, thus the pressure drop.

How many moles of a gas will 700 m hold at -100 oC and 86 atm?

bezimeni [28]

0.23 moles of a gas will 700 m hold at -100 oC and 86 atm.

Explanation:

given that:

volume = 700 ml OR 0.7 Litre (for converting into litre it is divided with 1000 as 1 litre = 1000ml)

temperature = -100 degrees OR 173.15 K

pressure = 86 atm

R = 0.082057 L atm mol-1K-1

n=?

It is known that when Volume is taken in litres, pressure in atm, and temperature in Kelvin then R= 0.082057 L atm mol-1K-1,

From the formula for ideal gas:

PV = nRT

putting the values in the formula:

n = $\frac{RT}{PV}$

= $\frac{0.0820507 X 173.15}{0.7 X 86}$

= 0.23 moles of the gas will be required.

Consider the substitution reaction that rakes place when (R)-3-bromo 3-methylhexane is treated with methanol. Which of the follo

Otrada [13]

Answer:

The reaction would take place with racemization.

Explanation:

The compound (R)-3-bromo 3-methylhexane contains has the leaving group attached to a tertiary carbon atom. When the leaving group is attached to a tertiary carbon atom, the compound undergoes nucleophilic substitution via SN1 mechanism. This mechanism involves the formation of a planar carbocation intermediate. The nucleophile may attack this intermediate from either faces, leading to racemization of the product.
