Increase in Oxygen shift the equilibrium towards reactant side.
<u>Explanation:</u>
6CO₂ + 6H₂O ⇄ C₆H₁₂O₆ + 6O₂
This is the reaction occurs in the photosynthesis of plants by means of sunlight. In this case, if the concentration of Oxygen increases or adding more oxygen to the product side will shift the equilibrium towards the reactant side according to the Le Chatlier's principle, which adjusts the equilibrium by itself for any changes that is increase or decrease in pressure, temperature or concentration of reactants or products.
Balanced equation:
Mg + 2 HNO3 —> Mg(NO3)2 + H2
This is a metal + acid reaction giving salt and hydrogen (not water).

Considering the definition of mass volume percentage, the percent concentration of dextrose is 45%.
<h3>Mass volume percentage</h3>
Mass volume percentage (% m/V) is a measure of concentration that indicates the number of grams of solute per 100 volume units of the solution. In other words, the volume percent of a component in the solution is defined as the ratio of the mass of the component to the volume of the solution, expressed as a percentage.
The mass volume percentage of a solution is determined by the following expression:

<h3>Percent concentration in this case</h3>
In this case, you know:
- mass of solute= 450 grams
- volume of solution= 1 L= 1000 mL
Replacing in the definition of mass volume percentage:

Solving:
<u><em>mass volume percentage= 45%</em></u>
Finally, the percent concentration of dextrose is 45%.
