Answer:
Mass of CO₂ produced = 5.72 g
Explanation:
Given data:
Mass of methane = 2.34 g
Mass of oxygen = 8.32 g
Mass of CO₂ produced = ?
Solution:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
Number of moles of methane:
Number of moles = mass/molar mass
Number of moles = 2.34 g/ 16 g/mol
Number of moles = 0.146 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 8.32 g/ 32 g/mol
Number of moles = 0.26 mol
Now we will compare the moles of carbon dioxide with oxygen and methane.
CH₄ : CO₂
1 : 1
0.146 : 0.146
O₂ : CO₂
2 : 1
0.26 : 1/2×0.26 = 0.13 mol
Less number of moles of CO₂ are produced by oxygen thus oxygen will react as limiting reactant.
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 0.13 mol × 44 g/mol
Mass = 5.72 g
Aqueous Solution - The expected precipitate would consist of Cu(OH)2.
What is aqueous solution?
An aqueous solution is one in which water serves as the solvent. Chemical equations typically illustrate it by adding (aq) to the appropriate chemical formula. For instance, Na+(aq) + Cl would be used to represent a solution of table salt, as well as sodium chloride (NaCl), throughout water (aq). The word aqueous, which derives from the word aqua, means that it is dissolved in or related to water. Water is a common solvent in chemistry due to its superior solvent properties and natural abundance. Since water is frequently used as a solvent in experiments, unless the solvent is specified, the word "solution" refers to an aqueous solution. A solution wherein the solvent is a liquid but not water is referred to as a non-aqueous solution.
