List 5 properties of a acids?
Acids can release hydrogen ions (H+) in solution. Acids can react with bases to form salts and water. Acids have a sour taste. Acids can conduct electricity when dissolved in water. Acids can change the color of acid-base indicators.
Are all acids and alkalis dangerous?
Everything depends on concentration and quantity !!By example:Acetic acid at 5% concentration is food grade vinegar, concentrated at 100% is called 'glacial' acid: a drop of it will burn through your skin, like concentrated sulfuric acid will do.Some (weak) organic acids are very toxic in small amounts (< 0.001 mg)

There are 20 choices for the first amino acid, 20 for the second, and so on, resulting in 20^5 = 3,200,000 distinct pentapeptides that can be made from the 20 amino acids.
What kind of substance tastes sour turns litmus paper red and has a pH of 5?
The substance is likely an acid, as acids taste sour, turn litmus paper red, and have a pH below 7. Examples of acids with a pH of 5 include vinegar (acetic acid) and citrus fruits (citric acid).
Nonsulfur photosynthetic bacteria use organic compound as?
CARBON SOURCES.... nonsulfur (purple & green) bacteria are photoheterotrophs, so they use organic compounds, such as alcohols, fatty acids, other organic acids and carbs, as sources of carbon. If using Tortora, Funke & Case Microbiology text, then you can read this in Chapter 5!

What are the four major organic molecules important in human?
The four major organic molecules important in humans are carbohydrates, lipids (fats), proteins, and nucleic acids (DNA and RNA). Carbohydrates are the primary source of energy, lipids are important for energy storage and cell structure, proteins are essential for cell structure and function, and nucleic acids carry genetic information.

What are the 5 acids?
There are far more than 5 acids. There are, however, 6 (some sources say 8) strong acids. They are: Hydrochloric acid (HCl) Hydrobromic acid (HBr) Hydroiodic acid (HI) Perchloric acid (HClO3) Nitric acid (HNO3) Sulfuric acid (H2SO4) Some sources also list Chloric acid (HClO3) and Periodic acid (HIO4) as strong acids. There are hundreds of weak acids. Common example include: Acetic acid (CH3CO2H) Formic acid (HCO2H) Carbonic acid (H2CO3) Phosphoric acid (H3PO4) Hydrofluoric acid (HF) Hydrosulfuric acid (H2S)
