Describe two uses of surfactants At least one must be something that was not described in the
passage For each example, explain how the
effects of the surfactant make it useful

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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