Explains why heating a liquid affects its viscosity? the molecules move faster at higher temperatures and overcome attractions more easily. the molecules move faster at higher temperatures, and the attractions between them increase. the molecules move slower at higher temperatures and overcome attractions more easily. the molecules move slower at higher temperatures, and the attractions between them decrease.

I think the correct answer is option 1. Heating a liquid affects the viscosity of the liquid because molecules move faster at higher temperatures and overcome attractions more easily. Overcoming the attractions in the substance would decrease the viscosity of the liquid.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
