How many grams of oxygen is needed to completely react with 9.30 moles of aluminum

Orlov [11]

Balanced chemical equation:

* moles of oxygen

4 Al + 3 O2 = 2 Al2O3

4 moles Al -------------- 3 moles O2
9.30 moles Al ---------- moles O2

moles O2 = 9.30 * 3 / 4

moles O2 = 27.9 / 4 => 6.975 moles of O2

Therefore:

Molar mass O2 = 31.9988 g/mol

n = m / mm

6.975 = m / 31.9988

m = 6.975 * 31.9988

m = 223.19 of O2

The splitting of carbon dioxide to form oxygen gas and carbon compounds occurs during

Oxana [17]

Answer:

neither photosynthesis nor respiration.

Explanation:

Photosynthesis is the process by which the green plants, in the presence of sunlight makes their own food. In the process carbon dioxide is absorbed and oxygen is released.

$6CO_2 + 6H_2O\ (sunlight)\ \rightarrow C_6H_{12}O_6 + 6O_2$

Respiration is the intake of oxygen and the metabolism of the glucose in which it is breakdown and releases carbon dioxide.

$C_6 H_{12}O_6 + 6O_2\rightarrow 6CO_2 + 6H_2O + ATP$

In neither of the two processes, carbon dioxide is splitted.
