EXTRACTION OF CAFFEINE 1.Explain the reason each step of the separation is performed with three portions of the solvent rather t

marissa [1.9K]

Answer:

Throughout the explanations section below you will find a description of the question.

Explanation:

(1)

Whether a solution would be positioned inside a separative funnel, combined water, as well as solvent, disintegrate particulate caffeine. In every stage, the caffeine content incorporated relies upon the coefficient of caffeine partitioning throughout the combination of water as well as fluid.
Thus, increasingly caffeine is taken from the solvent whenever the moment you bring additional solvent. Consequently, we separate the solvent from the single component.

(2)

For compounds to be mixed thoroughly and separated into different layers, a shuddering mixture within the dividing funnel would be essential.
However, it vibrates the separation funnel forcefully, restricts airflow within the funnel, which can also induce the fluid under it to burst or causing fluid to fire.

23 grams of sodium reacts with 293 cm 3 of water that is initially at 298 k. it produces an enthalpy change of 197 kj. what is t

m_a_m_a [10]

448 K is the final temperature of the water.

<h3>What is specific heat capacity?</h3>

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Given,

the mass of Na is 23 g

The volume of water = 293 cm3

Mass of water = 293 g

Total solution mass = 23 g + 293 g = 316 g

Specific heat capacity of water = 4.18 J/Kg

The equation relating mass, heat, specific heat capacity and temperature change is:

q = mcΔT

197 kJ = 316 g x 4.18 J/Kg x ( $T_{finals} - T_ {initial}$ )

197 kJ = 316 g x 4.18 J/Kg x ( $T_{finals}$ -298 K)

0.1491429956 x 1000 = $T_{finals}$ -298 K

149.1429956 + 298 = $T_{finals}$

447.1429956 = $T_{finals}$

448 K = $T_{finals}$

Hence, 448 K is the final temperature of the water.

<h3>What does a high specific heat capacity mean?</h3>

A high specific heat capacity means that it can store a large amount of thermal energy for a small change in mass or temperature.

Fill in the sentences below to explore the process by which a storm becomes a hurricane. some terms may be used more than once.

Reptile [31]

Answer:

The sentences which are made by the given sentences are as :

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.

Explanation:

Here in the question it has been mentioned to form the sentences with the given one:

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
A tropical disturbance leads to an array of clouds which are disorganized also there are thunderstorms with no rotation or little rotation with it.
When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
When the storm reaches a tropical storm stage it gets its name.
All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.

These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
