The following expression s proposed: ("(t, p xi-a r t (x1-x) + 42 pxn (a. 10 pts) reason out what the value of a must be. a correct answer without proper justification gets no credit. (b. 10 pts) obtain an expression for g if you found a value for a in part (a), use that value, otherwise use the symbol a. - (c. 10pts) what is (d. 10 pts) if 1 m/mol and 3 mmol, calculate the mixture k for x/-0.4

clouds form

solid ice forms on leaves.

water droplets form on grass.

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.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
