Match the following descriptions with the correct polysaccharide, note if you answer any part of this question incorrectly a sig

n read x will appears if one or more of the polysaccharides placed in correctly This polysaccharide is the storage form of glucose in the human body. This polysaccharide is the structural component of plant cell walls and cannot be digested by humans. The glucose units in this polysaccharide are joined only by 1,4glycosidic bonds glycogen The glucose units in this polysaccharide are joined by beat.1,4-glycosidic bonds Those two branched polysaccharides contain both alpha 1.4 and alpha 1,6-glycosidic bonds These two polysaccharides make up starch, the storage form of glucose in plants

Answer:

Glycogen. Cellulose. Amylose. Cellulose. Amylopetin and Glycogen. Amylopetin and Cellulose.

Explanation:

Glycogen is the form that glucose is stored in human body.

Cellulose is the structural part of plant cell walls and human cannot digest it.

Amylose is the polysaccharide linked mainly by the the bonds of \alpha 1,4 glycosidic.

Cellulose is an unbranched polysaccharide linked mainly by the bonds of  \beta 1,4 glycosidic.

Amylopetin and Glycogen are branched polysaccharides linked by the bonds of \alpha 1,4 glycosidic and \alpha 1,6 glycosidic.

Amylopetin and Cellulose are mainly stored in plants.

When you apply 1000 joules of energy to 50 grams of water its temperature changes to 30 degrees . What was the initial temperatu
expeople1 [14]

Answer:

25.2°C

Explanation:

Given parameters:

Energy applied to the water  = 1000J

Mass of water  = 50g

Final temperature  = 30°C

Unknown:

Initial temperature  = ?

Solution:

To solve this problem, we use the expression below:

            H  = m c Ф

H is the energy absorbed

m is the mass

c is the specific heat capacity

Ф is the change in temperature

     1000  = 50 x 4.184 x (30  -  initial temperature )

     1000  = 209.2(30 - initial temperature)

      4.78  = 30 - initial temperature

      4.78  - 30  = - initial temperature

         Initial temperature  = 25.2°C

I NEED HELP FAST!!!!! Can you tell me about the location of electrons in atoms and how energy affects their location??? I have a
Art [367]
Their locations can vary depending on the molecule they are associated with but they are usually in a "cloud " that is on the outside of an atom/molecule and if the atom is unstable the  electrons tend to be located farther away from the atom.

Identify the major attractive force in HF molecules.A) London Dispersion Forces (LDFs)
Llana [10]

Answer:

C) hydrogen bonding

Explanation:

All atoms and molecules have London Dispersion Forces between them, but they are usually overshadowed but the much stronger forces. In this scenario the major attractive force in HF molecules are hydrogen bonds. Hydrogen bonds are electrostatic forces of attraction found when Hydrogen is bonded to a more electronegative atom such as Oxygen, Chlorine and Fluorine.

Which of the following is true for balancing equations?
nataly862011 [7]

Answer:

D) There must be equal number of atoms of each elements on both sides of equation.

Explanation:

The balancing equation must have equal number of atoms of each elements on both sides of equation.

The balance equation shoes mass is conserved thus followed the law of conservation of mas.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
