Answer: both the different glycosidic linkages of the molecules and the different hydrogen bonding partners of the individual chains.
Explanation:
Glycogen is a polysaccharide of glucose which is a form of energy storage in fungi, bacteria and animals. Glycogen is primarily stored in the liver cells and skeletal muscle.
The difference in interchain stability between the polysaccharides glycogen and cellulose is due to the different glycosidic linkages of the molecules and the different hydrogen bonding partners of the individual chains.

what is water
a. a universal solvent
b. something you can drink
c.a liquid
Answer:
FIRST OPTION WHICH IS A: UNIVERSAL SOLVENT
Explanation:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

ammonia + oxygen ------> nitrogen + water
Answer:
Explanation:
Ammonia = NH3
Oxygen = O2
When these two (2) chemical elements react together, they form two chemical compound which are nitrogen oxide and water.
NH3 + O2 -----> NO + H2O
We would balance the chemical equation like this;
NH3 + 3O2 -----> 4NO + 2H2O
When a drawing of a circle made in the center of a piece of paper with a black marker gets wet, the marker bleeds, and as the water moves through the paper the ink separates into several colors.
Answer:
Chromatography
Explanation:
Chromatography is a technique for separating mixtures that involves the use of a moving liquid and filter paper. The solvent travels through the spots on the paper, taking the chemicals away in the opposite direction. If the solvent combination has been properly chosen, each of them will move at a different velocity than the others.

The graph shows the change in concentration of one of the species in the reaction
A + B + C→D.
If the graph indicates the reaction rate, then the concentration of which species is plotted?
A
B
C
D
Answer:
its D
Explanation:
Took the test
The specie whose concentration is plotted is D. The rate of reaction is how quickly or slowly hat a reaction proceeds.
Rate of reactionThe term rate of reaction refers to how quickly or slowly hat a reaction proceeds. A reaction rate plot involves the concentration of the species plotted against time.
Now we can see from the plot that concentration is increasing with time. Since the concentration of products increases with time, then the specie whose concentration is plotted is D.

What is the atomic mass of sulfur (S)?
Answer:
atomic mass of sulfur is 32.06 g/mol
Explanation:
The characteristics of a certain gas are listed in the table.
What is the expected density of the above sample of gas?
A - 3.16 g/L
B - 1.58 g/L
C - 1.21 g/L
D - 1.03 g/L
Answer:
Option A. 3.16 g/L
Explanation:
We'll begin by calculating the molar mass of Cl₂. This can be obtained as follow:
Molar mass of Cl₂ = 2 × 35.45
= 70.9 g/mol
Finally, we shall determine the density of Cl₂. This can be obtained as follow:
Molar mass of of Cl₂ (M) = 70.9 g/mol
Pressure (P) = stp = 1 atm
Temperature (T) = stp = 273 K
Gas constant (R) = 0.0821 atm.L/Kmol
Density (D) =?
D = PM / RT
D = (1 × 70.9) / (0.0821 × 273)
D = 70.9 / 22.4133
D = 3.16 g/L
Thus, the density of the gas is 3.16 g/L.
13.8g element consist 4.6 ×10^22 atoms what is atomic mass of element?
We know that,
4.6 x $ \sf{10^{22}}$ atoms of an element weigh 13.8g.Thus,
The atoms of $ \sf{ 6.02 \times 10^{13}}$ will weigh;
[tex] = \sf{\frac{13.8 \times 6.02 \times {10}^{23} }{4.6 \times {10}^{22} } } \\ [/tex]
[tex] = \sf{180.6 \: g \: \: (molar \: mass)}[/tex]
Hence, the molar mass (atomic mass) will be 180.6 g.why is it important of having regular supervision of the market?

Question:
Nearly the entire world uses the metric system for their measurements. The US is one in of three countries that does not use metric. Would you support changing school curriculum to teach the metric system as the primary measurement system in the US? Why or why not.
(It must be 3-5 sentences long please)
Answer:
I would
Explanation:
I would support the change to the metric system only because it allows children to understand smaller forms of units and measurements. Also, it will allow people in the math and science fields to broaden their knowledge of equations and formulas. Meaning that the scientist and mathematicians will be able to solve more problems in the world right now. Overall, the education system for the children of the United States would benefit from the change in the measurement system.

Catalysts help reactions happen more easily. This graph shows the energy of
a reaction without a catalyst. Which graph shows the energy of the same
reaction with a catalyst?
Answer:
D.
Explanation:
Catalysts are substances that increase the rate of a reaction i.e. make it faster. Catalysts do this by reducing the activation energy needed for a reaction to occur.
According to the image in this question, a graph showing the energy of a reaction without a catalyst is displayed. This means that a longer time will be spent. However, with a catalyst, the activation energy will reduce as seen in the image in option D.
The sum of the kinetic energies and potential energies of all of the molecules
in a substance is called the energy of the substance?
Answer:
The correct answer is - internal energy.
Explanation:
The movements of the particles are continuous inside In any substance/object, within random directions and with random speeds which are termed as Brownian motion.
Due to these movements, these substances have some kinetic energy and the interaction between particles takes place due to the presence of electrostatic intermolecular forces, this leads to having some potential energy. The sum of the kinetic energies and potential energies of the particles in a substance is called internal energy it is internal to the confines of the substance.

Answer:
the activation energy is 65-30
35
The activation energy of this reaction is 35 kJ.
What is activation energy?Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
The activation energy is equal to the difference between the threshold energy needed for the reaction and the average kinetic energy of all the reacting molecules.
The activation energy of a reaction is the difference in energy between the threshold energy and energy of the reactants.
Given,
The highest energy for a reaction to happen = Threshold energy = 65 kJ
Energy of the reactants = 30 kJ
Therefore, The activation energy of this reaction is 35 kJ.

Balance the reaction and determine which of the following coefficients
Answer:
B. The correct ratio is 3:1:1:3
Explanation:
According to this question, the following chemical equation was given:
CH3COOH + Al(OH)3 → Al(CH3COO)3 + H2O
This equation is obviously not balanced because the number of atoms of each element on both sides of the equation is not equal or the same. To balance the equation, we make use of coefficients as follows:
3CH3COOH + Al(OH)3 → Al(CH3COO)3 + 3H2O
- There are now 6 moles of C on each side
- There are now 15 moles of H on each side
- There are now 9 moles of O on each side
- There is now 1 mole of Al on each side
The correct ratio of each compound is in the order 3:1:1:3
