Answer:  A.  Removal of a water molecule between each two units

Explanation:  Carbohydrates are the those kinds of polymers which are made by the linkage of monomer units of monosaccharides.

Amino acids are the building blocks of the proteins or in other words, we can say that the amino acids are those smallest units from which the polymer like protein is formed.

Thus when 2 monomer units of monosaccharides are joined, condensation reaction will occur with the removal of the small unit like a molecule of water. Same thing happens with the formation of the protein.

Thus option (A) is the correct option.

What came first, Layer D or Rock E? <br><br> Layer D<br><br> Rock E
Leno4ka [110]

Answer:

Layer D

Explanation:

First means older.

Rock E is an intrusion, so it is younger than all the layers it pass through. Apparently, Rock E is the youngest layer. So, Layer D is came before Layer E.

Hope this helps!

Have a great day :)

You have 16.0 g of some compound and you perform an experiment to remove all of the oxygen, 11.2 g of iron is left. What is the
oksian1 [2.3K]

The empirical formula of this compound is equal to Fe_{2}O_3.

<h3>Empirical formula</h3>

To calculate the empirical formula of a compound, it is necessary to know the number of moles present.

Therefore, we will use the molar mass of iron and oxygen to find the amount of moles, so that:

MM_O = 16g/mol\\MM_Fe = 55.8g/mol

                                        MM = \frac{m}{mol}

  • Oxygen

                                            16 = \frac{4.8}{mol}

                                            mol = 0.3

  • Iron

                                   

                                               55.8 = \frac{11.2}{mol}

                                               mol = 0.2

Finally, as the empirical formula is composed of integers numbers of moles, just multiply the values ​​by the smallest common factor to transform into an integer, so that:

                                       O =>  0.3 \times 10 = 3moles

                                       Fe => 0.2 \times 10 = 2moles

So, the empirical formula of this compound is equal to Fe_{2}O_3

Which statement is accurate for these two sub-atomic particles.
krek1111 [17]

Answer:

The correct answer is "They are both located in the nucleus".

Explanation:

I had to look for the problem and found that the particles are a Proton and a Neutron.

The atomic nucleus is the central section of an atom, is positively charged and has almost the entire mass of the atom.

The nucleus is formed by protons and neutrons, which are held together by strong nuclear interaction, which allows the nucleus to be stable.

Have a nice day!

One mole of ar initially at 305 k undergoes an adiabatic expansion against a pressure pexternal = 0 from a volume of 8.5 l to a
PilotLPTM [1.2K]
An adiabatic process is when the system is insulated that no heat is released to the surroundings. For this type of process, we have a derived formula written below:

(T₂/T₁)^C = (V₁/V₂)
where C = Cv/nR

From the complete problem shown in the attached picture, Cv = (3/2)R. Thus,
C= (3/2)/1 mol = 3/2

(T₂/305 K)^(3/2) = (8.5 L/82 L)
Solving for T₂,
<em>T₂ = 67.3 K</em>

Check all that apply.
White raven [17]

Answer:

4 for C in CH4

+4 for C in CO2

-2 for O in all substances

+1 for H in both CH4 and H2O

option 1,2,3 and 4 are correct. Option 5 is not correct

Explanation:

Step 1: Data given

Oxidation number of H = +1

Oxidation number of O = -2

Step 2: The balanced equation

CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)

Step 3: The oxidation numbers

-4 for C in CH4

 ⇒ Oxidation number of H = +1

    ⇒ 4x +1 = +4

C has an oxidation number of -4

This is correct.

+4 for C in CO2

 ⇒ Oxidation number of O = -2

    ⇒ 2x -2 = -4

C has an oxidation number of +4

This is correct.

-2 for O in all substances

⇒ this is correct, the oxidation number of O is always -2 (except in H2O2 and Na2O2)

This is correct.

+1 for H in both CH4 and H2O

⇒ this is correct, the oxidation number of H is always +1 (except in metal hydrides).

This is correct.

+4 for O in H2O

 ⇒ Oxidation number of H = +1

    ⇒ 2x +1 = +2

The oxidation number of O is -2

This is not correct
