You are required to make 10mL of a 0.5M solution of HCl. Your stock solution of HCl is 90M. Using distilled water (dH2O) as a solvent, how much of each component will you need to make the desired final solution?

Answers

Answer:

0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Explanation:

From the dilution equation:

Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).

In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL

v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L

v1 = 0.0556 mL

This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,

 10 - 0.0556 = 9.944 mL

Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

What is Fermentation?

Fermentation is defined as a metabolic process that produces chemical changes in organic substrates through the action of enzymes which is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.

Microorganisms such as bacteria and fungi have metabolic genes that allow them to produce enzymes to break down a variety of sugar metabolites.

Yeast and sugar produce carbonic gas through fermentation which is why as the yeast consumes the sugar, it produces alcohol (ethanol) and carbonic gas (carbon dioxide) as waste products, hence the carbon dioxide trapped in the dough lifts up,

Thus, the trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.

First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.

The nervous system has been the most crucial organ system that acts as the command center. The CNS of the nervous system is very well protected by the bones. Thus, option D is correct.

What is CNS?

CNS has been abbreviated for the central nervous system which comprises the spinal cord and the brain. The spinal cord is located at the dorsal surface and the brain is at the anterior location of the body.

The CNS has been enclosed by the skeletal system as the spinal cord is confined inside the vertebral column and the brain inside the skull. They have cerebrospinal fluid that acts as the cushion that protects these structures from shock and injuries.

Which molecule separates the contents inside of the cell from the contents outside of the cell

Answers

Answer:

Which molecule separates the contents inside of the cell from the contents outside of the cell

Explanation:

cell membrane

Every cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.

The molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.

Lipids represent a broad range of biomolecules made up of carbon (C), hydrogen (H) and oxygen (O) atoms.

In some cases, lipids also contain phosphorus (P), nitrogen (N) or sulfur (S).

Lipids (i.e., phospholipids and cholesterol) represent the main biomolecules of the cell membrane whose function is to separate the interior of the cell from its surrounding environment.

In conclusion, the molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.
