Modify the predrawn structure of Tamoxifen to form the amine hydrochloride salt. Be sure to include the counter ion, and nonbonding electron pairs and charges where appropriate.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
