an irregularly shaped solid is dropped into a graduated cylinder filled with 45.00 mL of water. the water level with the object

in the cylinder Rises to 82.5 ml if the object has a mass of 73.5g what is the density of the object

The density of the object is 1.96 g/cm³.

Mass = 73.5 g

Volume = 82.5 mL – 45.00 mL = 37.5mL = 37.5 cm³

Density = mass/volume = 73.5 g/37.5 cm³ = 1.96 g/cm³

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

write a skeletal equation for the following reaction: An aqueous solution of barium nitrate and an aqueous solution of sodium su
belka [17]

Answer: skeletal equation : Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)

The products are sodium nitrate and barium sulphate.

balanced equation :  Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The skeletal equation is:

Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)

The balanced chemical equation is:

Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)
