= glucose molecule

= starch molecule

= protein molecule

= carbon dioxide molecule

= water molecule

= amino acid molecule

= oxygen molecule

Answers

Answer:

Explanation:

In creating this list, one will have to start from the atom (which is the smallest in the list) to the giant polymer (which is the largest in the group). The arrangement below will also be based on there molecular weight.

oxygen molecule (this is the first because it is an atom)

water molecule (this is lighter in weight than carbon dioxide)

carbon dioxide

amino acid molecule (most amino acids have a lesser molecular weight than glucose)

glucose (has a molecular weight of 180.156 g/mol)

protein molecule (several proteins have a lesser molecular weight than starch)

starch molecule (has a molecular weight of 359.33 g/mol)

The arrangement of molecules in the ascending order is: oxygen, water, carbon dioxide, amino acid, glucose, starch, and protein.  

• The size of the molecules can be determined by knowing their molecular weights.  

• The sum of the atomic weights of the atoms in the molecule is known as the molecular weight of the molecule.  

• The molecular weight of water is 18 gram per mole, glucose 180.2 g/mol, starch 360 g/mol, carbon dioxide 44 g/mol, protein 20000 g/mol, amino acid for example glycine 75 g/mol, and oxygen 16 g/mol.  

Thus, the molecules can be arranged with the smallest to the largest as oxygen, water, carbon dioxide, amino acid, glucose, starch, and protein.

A gas occupies 11.2 liters at 0.860 atm. What is the pressure if the volume becomes 15.0 L? (Boyle)

Answers

Answer:

0.642 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{11.2 \times 0.86}{15} = \frac{9.632}{15} \\ = 0.64213333...[/tex]

We have the final answer as

0.642 atm

Hope this helps you

Given:

Initial Volume [tex] \sf (V_1) [/tex] = 11.2 L

Initial Pressure [tex] \sf (P_1) [/tex] = 0.860 atm

Final Volume [tex] \sf (V_2) [/tex] = 15.0 L

To Find:

Final Pressure [tex] \sf (P_2) [/tex]

Concept/Theory:

[tex] \bf{ \underline{Boyle's \: Law} \: (Pressure - Volume \: Relationship)}[/tex]

"At constant temperature, the pressure of a fixed amount of gas varies inversely with the volume of the gas."

[tex] \bf{P \propto \dfrac{1}{V} \: (at \: constant \: T \: and \: n)}[/tex]

It can be also stated as "At constant temperature, the product of pressure and volume of fixed amount of a gas remains constant."

[tex] \bf{PV = Constant}[/tex]

If the initial pressure and volume of a fixed amount of gas at constant temperature are [tex] \sf (P_1) [/tex] & [tex] \sf (V_1) [/tex] and final pressure of the gas is [tex] \sf (P_2) [/tex] and volume occupied is [tex] \sf (V_2) [/tex], then according to Boyle's law;

[tex] \bf{P_1V_1 = P_2V_2 = Constant}[/tex]

OR

[tex] \bf{\dfrac{P_1}{P_2} = \dfrac{V_2}{V_1}}[/tex]

Answer:

By using Boyle's Law, we get:

[tex] \rm \longrightarrow \dfrac{0.860}{P_2} = \dfrac{15.0}{11.2} \\ \\ \rm \longrightarrow P_2 = \dfrac{11.2}{15.0} \times 0.860 \\ \\ \rm \longrightarrow P_2 = \dfrac{9.632}{15.0} \\ \\ \rm \longrightarrow P_2 = 0.642 \: atm[/tex]

[tex] \therefore [/tex] Final Pressure [tex] \sf (P_2) [/tex] = 0.642 atm

How many moles of nitrogen dioxide gas will be produced if 25.0 ml of 2M nitric acid react?

Cu + HNO3 = Cu(NO3)2 + NO2 + H2O

Answers

Answer:

0.025 moles of NO₂  will produced

Explanation:

Given data:

Moles of NO₂ formed = ?

Volume of HNO₃ = 25.0 mL

Molarity of HNO₃ = 2 M

Solution:

Chemical equation:

Cu + 4HNO₃   →        Cu(NO₃)₂ + 2NO₂ + 2H₂O

Number of moles of HNO₃:

Molarity = number of moles /  volume in L

2M = number of moles / 0.025 L

Number of moles = 2 M × 0.025 L

Number of moles = 0.05 mol

Now we will compare the moles of HNO₃  with NO₂  from balance chemical equation.

                                  HNO₃            :          NO₂

                                      4                :            2

                                 0.05               :         2/4×0.05 =0.025

0.025 moles of NO₂  will produced.

                                     

Carbon dioxide contains chemical bonds between oxygen and carbon. What particles are between the carbon and oxygen atoms? What keeps those particles between the atoms?

Answers

Explanation: i stuck at this Answer:Sometimes atoms share more than one pair of electrons, for example a double covalent bond can occur, as in the carbon dioxide molecule where carbon shares 2 pairs of electrons with each oxygen atom: O=C=O. (where = represents a double bond). Another kind of covalent bonding is called co-ordinate or dative covalent.

A polar covalent bond exists between the atoms in a CO2 molecule. A carbon atom is joined by four covalent bonds to two oxygen atoms, each of which has two covalent bonds.

What are chemical bonds?

A chemical bond is a long-lasting attraction between atoms, ions, or molecules that allows chemical compounds to form.

Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.

One carbon atom and two oxygens combine to form the carbon dioxide molecule.

Carbon has only four outer shell electrons, whereas oxygen has six. Double covalent bonds form between the atoms, with two electrons from each atom shared, for a total of four bonding electrons.

A CO2 molecule contains polar covalent bonds between its atoms. Four covalent bonds connect a carbon atom to two oxygen atoms, each of which has two covalent bonds.

Thus, this way bond gets formed between carbon and oxygen atoms.

Further explanation

Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product  

To predict whether this reaction can occur or not is one of them, the precipitation reaction. A precipitation reaction occurs if two ionic compounds which are dissolved reacted to produce one of the products of the ion compound does not dissolve. Formation of these precipitating compounds that cause reactions can occur  

Because A precipitate is formed, then compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ + are generally included in the insoluble compound

So the reaction :

you observe the light from a distant star through a spectroscopy. According to the belief that the universe is expanding from a single dense point ise the picture above to explain how it represents the ligt from the galaxy?​

Answers

Answer:

The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.

However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity. The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been expanding and may be infinite in its scope. The part of the universe of which we have knowledge is called the observable universe, the region around Earth from which light has had time to reach us.

One famous analogy to explain the expanding universe is imagining the universe like a loaf of raisin bread dough. As the bread rises and expands, the raisins move farther away from each other, but they are still stuck in the dough. In the case of the universe, there may be raisins out there that we can’t see any more because they have moved away so fast that their light has never reached Earth. Fortunately, gravity is in control of things at the local level and keeps our raisins together.The American astronomer Edwin Hubble made the observations in 1925 and was the first to prove that the universe is expanding. He proved that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. This is now known as Hubble’s Law. The Hubble Space Telescope was named after him, and the single number that describes the rate of the cosmic expansion, relating the apparent recession velocities of external galaxies to their distance, is called the Hubble Constant. It might be easier to explain about the beginning of the universe and the Big Bang Theory, than to talk about how it will end. It is possible that the universe will last forever, or it may be crushed out of existence in a reverse of the Big Bang scenario, but that would be so far in the future that it might as well be infinite. Until recently, cosmologists (the scientists who study the universe) assumed that the rate of the universe’s expansion was slowing because of the effects of gravity. However, current research indicates that the universe may expand to eternity. But research continues and new studies of supernovae in remote galaxies and a force called dark energy may modify the possible fates of the universe.

Explanation:

I hope I help :))

The big bang theory states that the universe started from a single dense point. This single point stretched and inflated gradually because of the expansion. The light from the galaxy shows an increase in the wavelength due to this expansion.

What does light from a galaxy tell about the expansion of the universe?

By looking at ultraviolet light, astronomers can tell which stars are forming in different galaxies and where they’re forming inside those galaxies. The ultraviolet and visible light coming from the most distant galaxies is converted into infrared light on its way through the expanding universe.

As the universe is expanding the galaxies are moving away from us. There is a shift in the wavelength of the light coming from these galaxies. This shift in the wavelength is referred to as redshift. This is because an expansion of the universe causes an increase in the distance between the two crests of the wave which results in the wavelength increase.
