Answer:
Explanation:
Hello there!
In this case, since the ionization of benzoic acid is:
Whereas the corresponding equilibrium expression is:
Now, we insert the acidic equilibrium constant and the reaction extent x, to write:
Thus, by solving for x, we obtain:
Which is also:
Best regards!
A conductor is a object that allows an electrical current to pass through it. An insulator does not let electrical currents pass through it but protect other objects from the electrical current. Conductors work to move currents to other spaces and Insulators work to minimize the transfer of heat energy.
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.
Answer:
A compound
Explanation:
Sugar is a compound because it contains the atoms of three different elements in a fixed ratio (C:H:O = 12:22:11).
An <em>element</em> contains only one type of atom.
<em>Mixtures</em> and <em>solutions</em> can have variable compositions.
I do believe the answer would be B. the flashlight represents the sun, the basketball represents the earth and the smaller softball would be the moon.
hope this helps
