Asupposedly silver crown is tested to determine its density. it displaces 10.7 ml of water and has a mass of 112 g. part a could the crown be made of silver?

The volume of water displace by crown is 10.7 mL. This will be equal to the volume of crown. Mass of crown is 112 g.

Density of a substance is defined as mass of substance per unit volume. It is mathematically represented as follows:

Putting the values,

The theoretical value of density of silver is also, 1 mL is equal to thus, density will be 10.5 g/mL.

This is approximately equal to the calculated value thus, the crown is made up of silver.

idk what the question is about

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.
