Answer:
Area of rectangle = 108 cm²
Given:
Base = 6 cm
Height = 18 cm
Explanation:
Area of rectangle = Base × Height
= 6 × 18
= 108 cm²
Answer:
B. Carbon shares 2 pair of electrons with each oxygen.
Explanation:
- Carbon dioxide is formed from combustion reactions, which involves a reaction between carbon and oxygen gas.
- Carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.
- The two atoms require to gain electrons to achieve a stable configuration; carbon require to gain four electrons and oxygen requires two electrons.
- Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total.

Since Qp>Kp , the reaction is not at equilibrium.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant shows the extent to which reactants are converted into products.
Now we have to obtain the Qp as follows;
Qp =[CH3OH]/[CO] [H2]^2
Qp = 0.265/(0.265) (0.265)^2
Qp = 14.2
Now we know that Kp = 6.09×10−3, Since Qp>Kp , the reaction is not at equilibrium.

molecular weight of toluene = 92 g/mol
C6 = 12 x 6 = 72
H5 = 1 x 5 =5
CH3 = 12 + 1 x 3 =15
molecular weight of benzene = 78 g/mol
C6 = 12 x 6 = 72
H6 = 1 x 6 = 6
moles toluene:
115.8 / (92 g/mol) = 1.25 mol
moles benzene:
45.2/ (78 g/mol) = 0.57mol
total moles: 1.25 + 0.57= 1.82 moles
mole fraction of toluene:
1.25 mol / 1.82 moles = 0.68
