Which of the followin separation methods is used in making coffee at home ? chromatography filtration - i think it’s this one fractional distillation simple distillation

Filtration

Explanation:

Chromatography : It is a type of separation process in which the liquid or gas is separated into components at different rate.

Filtration : It is a type of mechanical separation process in which the solid is separated from the liquid through the filter paper. The beans which are larger in size remain as such and the the coffee passes through the filter.

Fractional distillation is a process by which components in a chemical mixture are separated into different parts called as fractions according to their different boiling points.

Simple Distillation : It is a type of separation process in which the mixture of liquid separated or evaporated at different temperatures.

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.
