Balanced equation :
2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
Organic Nomenclature:
Hexane is a six-carbon straight-chain alkane. The prefix "hex-" signifies the number 6 for alkanes, and the suffix "-ane" is what clarifies that this hydrocarbon has only carbon-carbon single bonds. There are no double or triple bonds.
Elaborating the equation :
The mass of hexane available for this reaction is converted to a quantity of moles by multiplying by its density to get a mass and then dividing by its molar mass. This quantity of moles is then related to the quantity of moles of oxygen by their molar ratios. According to this balanced reaction equation, every 2 moles of hexane burned will require the reaction of 19 moles of oxygen gas.

I think the correct answer among the choices listed above is option B. Silicon oxide is the solid that contains two types of bonds because you have Si-Si bonds and Si-O bonds. That is two different covalent bonds. Hope this answers your question.
Answer:
B. 4 ham slices
Explanation:
A chemical reaction involves one or more substances known as reactants combining chemically to give one or more substances known as products.
Reactants in chemical reactions combine in definite mole or mass ratios to give products. Therefore, when one substance is present in excess of what is required to combine with another to form products, that substance is known as the excess reagent. The other substance which is present in a smaller amount and which when used up, the reaction stops is known as the limiting reagent.
From the illustration of the sandwiches in the question, the recipe for one sandwich represents the chemical equation of a reaction. The equation form is given below:
2 cheese slices + 1 ham slice + 2 bread slices ---> 1 sandwich
The ratio of the reactant is 2 : 1 : 2
From the available ingredients, 12 cheese slices, 10 ham slices, 12 bread slices.
12 cheese slices will require 6 ham slices and 12 bread slices to produce 6 sandwiches.
However, since there are 10 ham slices, 4 ham slices will be left over unused. This is the excess or leftover reactant.
