<span>Among the choices provided, the answer is letter C, CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s) since Iron(Fe) is higher up on the action graph and is, along these lines, more responsive than Copper(Cu). Because of this, Iron can supplant Copper in that substance equation. </span>

lord [1]

Answer:

Mendeléyev designed his table around the same time as a German chemist named Julius Lothar Meyer, who published it a year later. However, finally Mendeléyev's order was imposed. Do you know what his great success was? Help plis.

Mendeleev predicted the existence and properties of unknown elements that he called eka-aluminum, eka-boron, and eka-silicon, his table is based on atomic weight.

Explanation:

Gallium, scandium, and germanium were later discovered to coincide with his predictions. In addition to the fact that Mendeleev's table was published before Meyers, his work was more extensive, predicting the existence of other elements not known at the time.

3. Move the slider on the burette to the top to add about 25 mL of NaOH to the flask. What
UNO [17]

Answer:

When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue.

Explanation:

After reading your question, we can see that you are carrying out a test to discover the nature of the pH of a solution. This type of test uses litmus paper, which is an indicator of the presence of acids and bases, being able to determine the pH of a solution. This paper is soaked in organic ink and when placed in an acidic solution, it is red in color. However, when placed in a basic solution it has a blue color.

An acidic solution is one that has a high concentration of H+ atoms and has the ability to donate electrons. The basic solution, on the other hand, has a high concentration of OH- and has the capacity to receive electrons.

When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue, that is, the solution has the basic pH.
