What the approximate mass of 24cm of silver, if the density is 10.5 g/cm

Alona [7]

Use equation density = mass/volume
Known/Given

d= 10.5g/cm^3
v= 24.0 cm^3

Use that equation i just mentioned...
Solution
Rewrite the formula as the forumla for solving density into mass

Which is... mass = 10.5g/cm^3 × 24.0cm^3 = 252g

So thats the answer
252g

Hope i could help

Briefly compare and contrast the relative resistance to ph change of the seven solutions

JulsSmile [24]

PH stands for "Potential Hydrogen" and the PH scale ranges from 0-14. PH refers to the ability to attract hydrogen ions.

The PH of a solution either indicates acidity of the solution or alkalinity of the solution. A solution which has PH 7 above is a base solution where a solution with PH less than 7 is an acidic solution.

Ppredict the identity of the precipitate in the below reaction:<br><br> BaCl2(aq) + K2SO4(aq) →

Annette [7]

Answer: The precipitate formed is $BaSO_4$

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 or precipitated form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

$K_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2KCl(aq)$
