During resperation______.
Vikki [24]

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.

How many grams of water are made from the reaction of 4.0 grams of hydrogen gas with the given reaction 2H2+O2--->2H2O
Sergeeva-Olga [200]

Answer:

The mass of water is 36 g.

Explanation:

Mass of hydrogen = 4 g

Mass of water = ?

Solution:

First of all we will write the balance chemical equation:

2H₂ + O₂  →  2H₂O

Number of moles of hydrogen = mass / molar mass

Number of moles of hydrogen = 4 g/ 2 g/mol

Number of moles of hydrogen = 2 mol

Now we compare the moles of water with hydrogen from balance chemical equation.

                               H₂     :     H₂O

                                2      :       2

Mass of water = moles × molar mass

Mass of water =  2 mol × 18 g/mol

Mass of water =  36 g

If the water oxygen is in excess than mass of water would be 36 g.
