Praxis 5435 Latest Update 100% Correct absorption this occurs when waves pass through objects. The amplitude of a wave decreases as it passes through a medium acceleration the rate at which the velocity of an object changes over time. This will change if speed, direction, or both change. accuracy how close the measured values are to the true or actual value alkanes a type of hydrocarbon in which all carbon-carbon bonds are single bonds alkenes have at least one carbon-carbon dou...

Week 7 Concepts: Biochemistry LIPIDS In this concept, we will discuss one class of biological polymers called lipids or fats. You might be familiar with this class of biopolymers, which are found in butters and oils. We will discuss saturated and unsaturated fats, and what those terms mean for the molecule's structure as well as its properties at room temperature. 1. Which of the following is a source of lipids?  Sugar, fruits, and bread  Water  Steaks  Butter and oils ...

What are hybrid orbitals? - orbitals of equal energy produced by the combination of two or more orbitals on the same atom What are the types of hybrid orbitals - SP- 2 regions of density SP^2- 3 regions of density(3sp^2s) SP^3- 4 regions (4 sp^3s) What are the 4 types of hydrocarbons - alkanes, alkenes, alkynes, and aromatic hydrocarbons Alkane - a hydrocarbon containing only single covalent bonds Alkene - a hydrocarbon that contains one or more double bond between a carbon Alkyne - a hy...

OCR A LEVEL ORGANIC CHEMISTRY YEAR 12 WITH VERIFIED QUESTIONS AND ANSWERS What is the melting and boiling points of alkanes like? - ANSWER--as chain length increases so does the strength of the intermolecular forces as there is greater surface area for contact between molecules and hence stronger london forces and therefore the melting/boiling points are highr for longer chain. What is a structura/chain isomer? - ANSWER--Same molecular formula but a different structural formula Wh...
