<h3><u>Answer;</u></h3>
Ethane (C2H6) is the excess reactant
<h3><u>Explanation;</u></h3>
From the equation;
2C2H6 + 7 O2 → 4CO2 + 6 H2O
2 moles of ethane requires 7 moles of oxygen to produce 4 moles of CO2 and 6 moles of water.
The mole ratio of ethane : oxygen is 2 : 7
10 g of C2H6 = 10/30 g/mol = 0.333 moles
12.5 g of Oxygen = 42.5/32 g/mol = 1.328 moles
Using C2H6 as limiting; 0.333 moles pf C2H6 requires 0.333× 7 =2.331 moles of oxygen
Using oxygen as limiting; 1.328 moles of oxygen requires, 1.328/7 = 0.1897 moles of ethane.
Therefore; Ethane is the excess reactant by 0.333 - 0.1897 = 0.1433 moles

Explanation:
Structural isomer is a type of isomer in which molecules with the same molecular formula have different bonding patterns and atomic organization.
For example Pentan-1-ol, pentan-2-ol, and pentan-3-ol are structural isomers that exhibit position isomerism.
Cyclohexane and hex-1-ene are examples of functional group structural isomers.
True.
Because some people breathe less pollution and face lower risks of premature death and other serious health
