Which of the three objects has the greatest density? Why? (GOLD BARS/GOLD COINS/GOLD CHAIN)

They all have the same density

Explanation:

Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.

It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is .

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.
