C5h12 + 8o2 10co2 + 6h2o what is the mole ratio of oxygen to pentane? 1: 6 6: 8 8: 1 10: 8

8:1

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The give balanced chemical equation is:

According to stoichiometry:

8 moles of oxygen reacts with 1 mole of pentane and thus mole ratio of oxygen to pentane is 8:1

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
