Glucose generally exists in ring (cyclic) form. a haworth projection shows the orientations of the hydroxyl groups and hydrogen

atoms on the ring. draw the α and β forms of glucose by moving the groups (h, oh, or ch2oh) to the appropriate positions. for the hydroxy groups, make sure the bond on the ring is bonded to the oxygen, not the hydrogen.

The right answer is in the picture (alpha and beta glucose)

Glucose is the main source of energy in the body. It is a carbohydrate found in the diet, usually linked to more complex carbohydrates. It is once arrived in the intestine and degraded by enzymes during digestion that simple glucose is synthesized. The glucose is then converted into glycogen which is stored in the muscles and in the liver (reserve available for the entire body). In general and without any pathology, the blood glucose level is kept constant.

In the human body, both forms of glucose exist, with a predominance of beta-D-Glucose in the blood (66%).

A 75 lb (34 kg) boy falls out of a tree from a height of 10 ft (3 m). i. What is the kinetic energy of the boy when he hits the
Jobisdone [24]

Answer:

Kinetic energy of boy just before hitting the ground is \approx1000 J.

Speed of boy just before hitting the ground is 7.67 m/s

or 17.16 mi/hr.

Explanation:

Given that:

Mass of boy = 75lb = 34 kg

Height, h = 10ft = 3m

To find:

Kinetic energy of boy when he hits the ground.

<em>As per law of conservation of energy The potential energy gets converted to kinetic energy.</em>

<em></em>

<em></em>\therefore<em> </em>Kinetic energy at the time boy hits the ground = Initial potential energy of the boy when he was at the Height 'h'

The formula for potential energy is given as:

PE = mgh

Where m is the mass

g is the acceleration due to gravity, g = 9.8 m/s^2

h is the height of object

Putting all the values:

PE = 34 \times 9.8 \times 3 \approx 1000\ J

Hence, Kinetic energy is \approx1000 J.

Formula for Kinetic energy is:

KE = \dfrac{1}{2}mv^2

where m is the mass and

v is the speed

Putting the values and finding v:

1000 = \dfrac{1}{2}\times 34 \times v^2\\\Rightarrow v^2 = 58.82\\\Rightarrow v = 7.67\ m/s

Given that:

1 m = 1.094 yd and 1 mi = 1760 yd

\Rightarrow 1609\ m = 1\ mi

Converting 7.67 m/s to miles/hour:

\dfrac{7.67 \times 3600}{1609}=17.16\ mi/h

1. Which liquid sample is a pure substance?
IRISSAK [1]

The whole Activity , poem and paragraph is missing in the question.

Answer:

(1) Liquid A

(2) Solid A

Explanation:

Using this part of the given poem

Substances and mixtures behave differently,

During boiling and melting most especially

Boiling point of substance is fixed while mixture is not

Substance melts completely but mixture does not

The boiling point of the Pure substance remain fixed after reaching its boiling point this is shown by Liquid A

Solid A is melting completely so Solid A is a pure substance.

What is the density ρh of hot air inside the balloon? assume that this density is uniform throughout the balloon. express the de
enyata [817]

Answer 1) : The density of the hot air inside the balloon can be found out by using ideal gas equation;


PV = nRT;


As n is number of moles and in gases, number of moles along with mass per mole is equal to the density of the gas.


If the moles in the gas are more the density will be more.


here, density (ρ) = mass (m) / volume (V); substituting in the ideal gas equation we get,

ρ = mP / RT


Answer 2) ρ (hot air) = ρ (cold air) X \frac{T_{h}}{T_{c}}

Here according to the formula because T(hot air) >T(cold air),


So, the density of hot air greater than the density of cold air.


The relationship between the ρ (h) = ρ(c) X \frac{T_{h}}{T_{c}}
