Answer:
Explanation:
Ca(In)²⁺ + EDTA → Ca(EDTA)²⁺ + In
We use the volume of EDTA consumed in the titration to <u>calculate the moles of Ca⁺² ions</u>:
- 0.012 L * 0.0600 M * = 7.20x10⁻⁴ mol Ca⁺²
Now we <u>calculate the molarity</u>:
- 7.20x10⁻⁴ mol Ca⁺² / 0.050 L = 0.0144 M
To calculate in ppm, we <u>use the moles of Ca⁺² and convert to mg of CaCO₃:</u>
- 7.20x10⁻⁴ mol Ca⁺² = 7.20x10⁻⁴ mol CaCO₃
- 7.20x10⁻⁴ mol CaCO₃ * 100g/mol * = 72 mg CaCO₃
Finally, <u>the concentration in ppm</u> is:
- 72 mg CaCO₃ / 0.050L = 1440 ppm
Photosynthesis takes carbon dioxide, water and sunshine and turn them into glucose and oxygen
Explanation
Glucose is the principal carbohydrate formed through photosynthesis, Through the process of photosynthesis sunshine, carbon dioxide and water to form glucose and oxygen
Equation for reaction is as follows
CO2+ H2O + light energy → C6H12O6 +O2
C6H12O6 is the glucose
The answer is
