Oxidation of D-glucose are usually found on the photosynthesis which has a by product of carbon dioxide (CO2) and water  (H2O) chemically written as,

C6H12O6 +6O2----> 6CO2 +6H2O

Moreover, D-glucose can also be chemically react with oxygen to form D-gluconic acid and D-glucoronic acid.

The density of helium is 0.17 g/L. What Is the mass of helium in a 5.4 L helium balloon? (2 sig figs) *
ioda

Answer:

The correct answer is 0.92 g

Explanation:

The density is defined as the mass per unit of volume:

Density= mass/volume

From the data provided:

volume= 5.4 L

density= 0.17 g/L

Thus, to calculate the mass of helium:

mass= density x volume = 0.17 g/L x 5.4 L= 0.918 g ≅ 0.92 g

For the reaction PCl5(g) + heat PCl3(g) + Cl2(g), what will happen when the volume is increased?
Fiesta28 [93]
Answer: There will be a shift toward the products. 

The effect of increasing volume will be similar to decreasing pressure, it will shift the equilibrium into the side with higher molecule count. In the reaction above, the product molecule count is 1 (one PCl5) while the product is 2 (one PCl3 + one Cl2). So, increasing volume will increase the rate of product formation.
