Question 5 How does physical dependence differ from psychological dependence? A physical dependence produces a strong drive to want the substance. A psychological dependence causes problems in the person’s life. A physical dependence means that the substance increases release of dopamine. With a physical dependence, quitting leads to withdrawal symptoms. Question 6 What did Solomon Asch measure in his study of conformity?

please I need help with the data sheet
INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...

INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...

54.A nurse is planning a staff education program on substance use in older adults. Which of the following is appropriate for the nurse to include in the presentation? A. Older adults require higher doses of a substance to achieve a desired effect B. Older adults commonly use rationalization to cope with a substance use disorder C. Older adults are at an increased risk for substance use following retirement. D. Older adults develop substance use to mask manifestations of dementia 55.A...

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
