The most basic level of organization that is involved in converting fuel or food into forms of energy, are found and compose living things. These are called cells.
The pH of 0.20 M HF (Hydrofluoric acid) is 3.27. Whereas, [H₃O⁺] for the same is 6.8 X10 ⁻⁴
<h3>
What is Hydrofluoric acid?</h3>
A hydrogen fluoride and water solution is hydrofluoric acid. HF solutions are colorless, corrosive, and acidic. The majority of fluorine-containing chemicals are made using it; examples include the substance PTFE and the widely used psychiatric drug fluoxetine. Aluminum, plastics, electrical components, pharmaceuticals, high-octane fuel, fluorescent light bulbs, and refrigerants are all made with hydrogen fluoride. The production of refrigerants uses 60% of the hydrogen fluoride used in manufacturing. corrosive due to the acid's H+ ions and poisonous due to the fluoride ions F-, which can penetrate deeply, chelate calcium and magnesium, and thus upset biological balances due to the destruction of the skin's or an eye's outermost layer.

Answer:
1 × 10⁻⁵ M
Explanation:
Step 1: Given data
- Concentration of chlorine: 1 mg/L
Step 2: Convert the concentration of chlorine from mg/L to g/L
We will use the conversion factor 1 g = 10³ mg.
1 mg/L × 1 g/10³ mg = 1 × 10⁻³ g/L
Step 3: Convert the concentration of chlorine from g/L to mol/L (molar)
We will use the molar mass of chlorine: 70.91 g/mol.
1 × 10⁻³ g/L × 1 mol/70.91 g = 1 × 10⁻⁵ mol/L = 1 × 10⁻⁵ M
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
