Answer: 125 grams
Explanation: (125mL)*(1.0g/mL) = 125g
D. oxygen is used to break down glucose into energy
Explanation:
During respiration, oxygen is used to break down glucose into energy:
C₆H₁₂O₆ + O₂ → CO₂ + H₂O + energy
In the process of respiration, oxygen gas combines with glucose to liberate energy.
- Respiratory system in the body is responsible for the metabolic break down of food to provide energy for the working of the human body.
- Chemical energy in glucose is broken down to produce other forms of energy most especially heat.
- The by product is usually carbon dioxide and water vapor.

Answer:
Explanation:
Initial burette reading = 1.81 mL
final burette reading = 39.7 mL
volume of NaOH used = 39.7 - 1.81 = 37.89 mL .
37.89 mL of .1029 M NaOH is used to neutralise triprotic acid
No of moles contained by 37.89 mL of .1029 M NaOH
= .03789 x .1029 moles
= 3.89 x 10⁻³ moles
Since acid is triprotic , its equivalent weight = molecular weight / 3
No of moles of triprotic acid = 3.89 x 10⁻³ / 3
= 1.30 x 10⁻³ moles .
