2 _ Pb(SO )2 - LINO: –> Pb(NO3)4 + Li2SO4
li a student mixes 14 moles of C4H10O with 15 moles of O2: how many moles of Co2 can be
made?

Moles of CO₂ produced = 10 mol

Explanation:

Given data:

Number of moles C₄H₁₀O =  14 mol

Number of moles of O₂ = 15 mol

Moles of CO₂ produced = ?

Solution:

Chemical equation:

C₄H₁₀O  +  6O₂  →     4CO₂ + 5H₂O

Now we will compare the moles of CO₂ with both reactants.

                      C₄H₁₀O           :             CO₂

                              1              :               4

                            14              ;          4×14 = 56 mol

                            O₂              :               CO₂

                              6               :                 4

                             15               :             4/6×15 = 10 mol

So oxygen will be limiting reactant and moles of CO₂  produce are 10.

Ionic bond is a chemical bond formed by the complete transfer of electrons between two atoms. The atom that loses electrons gains a positive charge (cation) and that which accepts electrons gains a negative charge (anion). Now, electronegativity is a parameter that measures the tendency of an atom to accept electrons. In the context of ionic bonding, two elements which show a significant difference in their electronegativity values form ionic bonds.

In the given examples, the difference in electronegativity is greatest between K  and Br i.e. 0.8 and 2.8 respectively with a difference of 2.0. This also makes sense since K and Br are on the extreme ends of the periodic table. Hence, potassium with a valence electron configuration of 4s1 will lose its s electron to Br (4s24p6) and form an ionic molecule K⁺Br⁻
