Question

a compound is a substance formed when two or more chemical elements are chemically bonded together. the type of bonds holding elements together in a compound can vary - two common types are covalent bonds and ionic bonds. the elements in any compound are always present in fixed ratios. glucose is a 6 - carbon sugar made by autotrophs in the process of photosynthesis. it is a compound formed from three elements: carbon, hydrogen, and oxygen. the ratio of hydrogen to carbon and oxygen in glucose is always 2:1:1. what is the correct molecular formula for glucose? a c₂ho b c₆h₁₂o₁₂ c c₆h₁₂o₆

Explanation:

Step1: Recall glucose properties

Glucose is a 6 - carbon sugar with hydrogen to carbon to oxygen ratio of 2:1:1.

Step2: Analyze each option

For option A ($C_3HO$), the ratio and number of carbons are wrong. For option B ($C_6H_{10}O_{12}$), the ratio is incorrect. For option C ($C_6H_{12}O_6$), there are 6 carbons, 12 hydrogens and 6 oxygens, which gives a 2:1:1 ratio of hydrogen to carbon to oxygen.

Answer:

C. $C_6H_{12}O_6$
