Octane the primary resource of energy in gasoline, reacts according to the equation
2C3H18 + 2502 -->16CO2 + 18H20
How many moles of H20 are produced when 3.0 moles of Octane CgH18 undergoes
combustion in the presence of excess oxygen?
2
3.0
6.0
27

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:

Reduction is a reaction which results in a in electrons and a in positive charge of the atom or ion 1) a- loss 1) b- gain 2) a-increase 2) b-decrease

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.
