The volume of the object=6.71ml

Given:

Mass of the object=36.240g

Density of the object=5.40\frac{g}{m l}

To find:

Volume of the object

<u>Step by Step Explanation:</u>

Solution:

According to the formula, Density of the object is given as

\rho=\frac{m}{v} and from this volume can be derived as

v=\frac{m}{\rho}

Where, m=mass of the cylinder

\rho=density of the cylinder

v=volume of the cylinder

We know the values of m=36.240g and \rho=5.40\frac{g}{m l}

Substitute these values in the above equation we get

v=\frac{m}{\rho}

v=36.240/5.40

=6.71ml

Result:

Thus the volume of the object is 6.71ml

Identify some other substances (besides KCl) that might give a positive test for chloride upon addition of AgNO3. do you think i
nlexa [21]

Answer:

-The other substances that give a positive test with AgNO3 are other chlorides present, iodides and bromide.

-It is reasonable to exclude iodides and bromides but it is not reasonable to exclude other chlorides

Explanation:

In the qualitative determination of halogen ions, silver nitrate solution(AgNO3) is usually used. Now, various halide ions will give various colours of precipitate when mixed with with silver nitrate. For example, chlorides(Cl-) normally yield a white precipitate, bromides(Br-) normally yield a cream precipitate while iodides (I-) normally yield a yellow precipitate. Thus, all these ions or some of them may be present in the system.

With that being said, if other chlorides are present, they will also yield a white precipitate just like KCl leading to a false positive test for KCl. However, since other halogen ions yield precipitates of different colours, they don't lead to a false test for KCl. Thus, we can exclude other halides from the tendency to give us a false positive test for KCl but not other chlorides.
