Ques:Answer the following question given this paragraph: A hydrocarbon is an organic compound that is made up of only carbon and hydrogen. A hydrocarbon is the simplest kind of organic molecule and is the basis for all other more complex organic compounds. Hydrocarbons can be divided into two broad categories. Aliphatic hydrocarbons are hydrocarbons that do not contain the benzene group or a benzene ring . Aromatic hydrocarbons contain one or more benzene rings. In this concept, we will discuss the aliphatic hydrocarbons. Q: What is an organic compound that is made up of only carbon and hydrogen? Choices: - an acid - a catalyst - a component - a hydrocarbon A:

Ques:Answer the following question given this paragraph: An alternative way to define the concentration of a solution is molality, abbreviated m. Molality is defined as the number of moles of solute in 1 kg of solvent. How is this different from molarity? Would you expect a 1 M solution of sucrose to be more or less concentrated than a 1 m solution of sucrose? Explain your answer. What are the advantages of using solutions for quantitative calculations?. Q: The number of moles of solute in 1 kg of solvent is defined as what? Choices: - singularity - pollenation - kilocalorie - molarity A:

Ans:molarity
