Add Lime Water to the solution. If Carbon Dioxide is present the solution should go a white, milky colour due to the Calcium Hydroxide (chemical name for Lime Water) reacting with the Carbon Dioxide to form Calcium Carbonate.
Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
- H: Cytoplasm
- E: Lysosome
- F: Mitochondria
- A: Centriole
- G: Endoplasmic reticulum
- ?: Vacuole
- D: Cell membrane
- J: Nucleus
- L: Ribosome
- C: Nuclear membrane
- B: Golgi apparatus
- K: Vesicle
- I: Nucleolus
There is no function/description that accurately matches up with the vacuole. In fact, there are 13 organelles provided and only 12 functions/descriptions listed; presumably, the description/function of the vacuole is the one that is missing.
There is not enough information to determine anything about the relative abundances of the two isotopes.
<h3>What are isotopes?</h3>
Isotopes are atoms that have the same atomic number but different mass numbers. We know that all the isotopes of an element are not available to the same extent in nature.
Hence, from the average atomic mass of carbon, we can see that there is not enough information to determine anything about the relative abundances of the two isotopes.
