Answer:

In humans, up to ten different proteins can be traced to a single gene. Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren't all produced by all the body's cells at any given time. Cells have different proteomes depending on their cell type.

Explanation:

Proteins are macromolecules that are complex structures made of monomeric units. There are 20,000 - 60,000 different kinds of proteins in the human body.

Proteins have been the large molecules (macromolecules) that are structurally composed of the monomers or the smaller units. They have been composed of amino acids.

The amino acids are produced by the translational process and are linked by the peptide bonds. They are the most essential compound for the cellular and physical activity of the cells in living organisms.

The proteome is used to identify and classify the various proteins that can range from 20,000 - 60,000 in a human body. These proteins are involved in performing the functions in the body.

Therefore, approximately 20,000 - 60,000 proteins are found in the human body.

Answer:

57 mL

Explanation:

To make things clear, when 769 mL of ethanol were mixed with 507 mL of water, the resulting volume was not (769+507) 1276 mL, but a lower value. This is because of the interactions between liquid molecules.

First we calculate how many grams of ethanol are there in 769 mL, using the given density:

Then we convert 606.97 g of ethanol into moles, using its molar mass:

Now we calculate the actual volume of the solution, using the definition of molarity:

Finally we convert 1.219 L to mL, and calculate the difference in volume:

Answer:

CH3COOH would be more concentrated

Explanation:

The higher the concentration value, the more concentrated it is.

The relationship between concentration, moles and volume is given by the equation;

Concentration = No of moles / Volume

5.0 grams of HCOOH dissolved in 189 mL of water

Number of moles = Mass / Molar mass = 5 / 46.03 = 0.1086 mol

Concentration = 0.1086 / 0.189 = 0.5746 mol/L

1.5 moles of CH3COOH dissolved in twice as much water

Volume = 2 * 189 = 378 ml = 0.378 L

Concentration = 1.5 / 0.378 = 3.9683 mol/L

Comparing both concentration values;

CH3COOH would be more concentrated

Answer: FeCl3+O2-->Fe2O3+Cl2  is NOT balanced

Explanation:You first need to balance the equation.  The balanced equation would be...

4FeCl3 + 3O2 ==> 2Fe2O3 + 6Cl2

moles FeCl3 present =4 moles

moles O2 present = 4 moles

Since the mole ration in the balanced equation is 4 FeCl3 : 3 O2, the limiting reactant will be FeCl3

moles Cl2 that can be produced = 4 moles FeCl3 x 6Cl2/4 moles FeCl3 = 6 moles Cl2

Explanation:

The amount of chlorine will be 0.791 gram required to completely react with 0.0223 moles of sodium iodide .

The given chemical reaction is :

2Nal + [tex]Cl_{2}[/tex] → 2NaCl + [tex]I_{2}[/tex]

It is given that:

Amount of sodium iodide = 0.0223 mol.

Atomic mass of chlorine = 35.45 g.

The amount of chlorine can be calculated as:

0.0223mol. NaI × (1mol. Cl₂/2mol. NaI) × (35.45g/1mol. Cl2)

=0.791 grams

Therefore, the correct answer will be option (D).

Answer:

The mass of water produced is 4.29 g.

Explanation:

Given;

reacting mass of ethane, C₂H₆ = 2.5 g

reacting mass of oxygen, O₂ = 5.0 g

The balanced combustion reaction is given as follows;

2C₂H₆   +   7O₂ ---------------->  4CO₂    +   6H₂O

Based on the balanced equation above;

                                     requires

7.0 moles of oxygen ----------------------->   2.0 moles of ethane

                                   requires

5.0 g of oxygen      -------------------------->  x gram of ethane

x = (2 x 5) / 7

x = 1.43 g

Ethane is in excess of 1.07g (2.5 g - 1.43g)

Now, determine the mass of water produced by 1.43 g of ethane;

                                   requires

2.0 moles of ethane ----------------------->   6.0 moles of water

                                   requires

1.43 g of ethane      -------------------------->  y  gram of water

y = (6 x 1.43) / 2

y = 4.29 g

Therefore, the mass of water produced is 4.29 g.

Answer:

4.26m

Explanation:

Molality , m, is an unit of concentration in chemistry defined as the ratio between moles of solute (In this case, NaCl) and kg of solvent (In this case, water).

To solve the question we need to find the moles of NaCl and the mass of water in kg:

Moles NaCl -Molar mass: 58.44g/mol-:

11.7g * (1mol / 58.44g) = 0.200 moles

Mass of Water in kg:

47g * (1kg / 1000g) = 0.047kg

Molality is:

0.200 moles / 0.047kg =

Explanation:

Air over the beach heats up, rises, and is replaced by cool, denser ocean air

The ocean heats up much slower and becomes relatively cooler than the beach making it a high pressure zone. The air moves from the water to the land each morning forming a sea breeze. These pressure zones might equal out later in the day and the winds may diminish. ... A sea breeze blows from the ocean towards the beach.
